The Great Sabbath (Shabbat ha-Gadol) on Nisan 10

By Shabbat ha-Gadol (Hebrew translated 'the Great Sabbath') the Israelites refer to the Sabbath preceding the Passover, which begins from the preparation day on Nisan 14 (the day of the killing of the lamb). But the actual Feast of Unleavened Bread always begins from the 15th of Nisan, the first feast day (High Sabbath) of the year. Here, then, a precise distinction must be made between the weekly Great Sabbath (Shabbat ha-Gadol) on Nisan 10 and the first annual Great Sabbath (feast day) on Nisan 15. However, since, according to God's astronomical calendar, the 10th of Nisan falls on a Sabbath only about every third year, but otherwise on other days of the week, the Sabbath before Passover is also called Shabbat ha-Gadol in those years, even though it does not fall on the 10th of Nisan. Thus, each year the Jews commemorate the separation of the Lamb on the Sabbath, the 10th of Nisan in the year of the Exodus from Egypt. This teaching is also confirmed in the Talmud, which dates the 15th of Nisan (and thus the Exodus) on a Thursday, which means that the 10th of Nisan must have fallen on a Sabbath: 

„As to Nissan in which the Israelites departed from Egypt, on the 14th they killed their Passover sacrifices, on the 15th they went forth, and in the evening the firstborn were smitten... and that day was a Thursday.“ (Shabbath 87b).

Why is this significant not only for the Israelites, but also for Christians? The answer will be very shocking to many Christians: Hebrews assumes that the very first Passover lamb was set apart in Egypt on the Sabbath, the 10th of Nisan. This means that the 14th of Nisan in the year of the Exodus must have fallen on a Wednesday and the 15th of Nisan (feast day) on a Thursday! Since the New Testament (NT) describes exactly the same sequence of days in the year of Jesus' crucifixion, this means that Jesus fulfilled the symbolism of the Passover lamb in a perfect way. Not only did He die on the same day, Nisan 14 according to God's calendar, but even on the same day of the week (Wednesday) and at the exact same time (3 p.m.) that the first Passover lamb died, whose blood saved the nation of Israel from destruction. There is no mention of an alleged separation of the Lamb on a "Palm Sunday" and an alleged exodus on a Sabbath/Saturday, which many Sunday worshippers desire (to justify the theory of Jesus' alleged Sunday resurrection), either in the NT or in all Hebrew literature. The following sequence of days is confirmed not only in the Bible, but also in the main Israeli sources from several centuries, namely: 

Nisan 10, Sabbath: separation of the lamb. Shabbat ha-Gadol.

Nisan 14, Wednesday: slaughter of the lamb at 3 p.m. (between the two evenings).

Nisan 15, Thursday: Exodus from Egypt, which already began in the night phase of the High Sabbath. Feast day.

The many Jewish sources and data confirm 100% the events mentioned in the resurrection chapter of the NT, namely:

Nisan 10, Sabbath: Separation of the Lamb: Jesus enters Jerusalem: Palm Sabbath. Shabbat ha-Gadol.

Nisan 14, Wednesday: slaughter of the lamb at 3 p.m. (between the two evenings). Jesus dies.

Nisan 15, Thursday: Exodus from the death penalty, because through Jesus we were freed, therefore a great feast.

Nisan 16, Friday: preparation day for the Sabbath, women prepare the ointments on the day between the two Sabbaths. 

Nisan 17, First Sabbath (Mark 16:9): resurrection of Jesus after "3 days and 3 nights" as He said.

In the year of Jesus' crucifixion there was no „Palm Sunday,“ but rather a „Palm Sabbath“.

So the information with the chronological order of the Passover events in the New Testament (NT) coincides exactly with the tradition of the Hebrews. Jesus must therefore have entered Jerusalem on the great Sabbath (10th of Nisan, the day of the separation of the lambs). So the alleged Palm Sunday was actually a Palm Sabbath, as many Christians have reported for centuries (see Palm Sabbath on 10th Nisan). Jesus was then crucified after 4 days on Nisan 14, i.e. on a Wednesday, and died exactly at the time when the Passover lambs had to be slaughtered, i.e. at 3 pm. See the detailed documentation on the events of 14th of Nisan. After that, starting at sunset, the 15th of Nisan (the High Passover Feast Day of the Deliverance and Exodus) began, and Jesus would thus have been resurrected after "3 days and 3 nights" on a Sabbath, as all evangelists unanimously report in the basic Greek text and in many translations (Mt 28:1;  Mk 16:2;  Lk 24:1;  Jn 20:1;  Jn 20:19).

Mark makes it even much clearer, naming the resurrection Sabbath as the "first Sabbath" (Mk 16:9). What is the first Sabbath? If the Christians had studied the Old Testament (OT), which was the spiritual foundation of Jesus and the first Christian church (because there was no NT yet), they would have known that this "first Sabbath" exists only once a year. All the Jews knew which Sabbath was meant. It is as if today someone would say on the "first Advent Sunday", so everyone would know which Sunday in the year is meant. So also the "first Sabbath" is unique, it is the first Sabbath of a series of exactly 7 weekly Sabbaths that must be counted each year between Passover (Nisan 15) and Pentecost (the 50th day after the first High Sabbath) (see Omer Counting). This counting of the 7 Sabbaths exists only once a year, just as the counting of the 4 Sundays of Advent also exists only once a year.

Without knowing it, the Jews (and the Talmud) confirm the statements in the resurrection chapter of the New Testament, for they state in their own sources that the first Passover lamb was set apart on a Sabbath, the 10th of Nisan, whose blood shed on the 14th of Nisan (Wednesday) spared, saved and delivered the Israelites on the night of the Exodus (on the 15th of Nisan, Thursday). What is said here is by no means a new teaching, even Wikipedia (translated) reports: 

„The term "Great Shabbat" dates back to Rashi in the 11th century. There are different views on the origin of the expression: On the one hand, there is a reference to the miracles associated with the Exodus from Egypt. In this regard, the German Jewish Encyclopedia, published in 1927, notes that the Shabbat immediately preceding Passover is called Shabbat ha-Gadol because "the 10th of Nissan, on which the Passover sacrifice was once provided before the night of liberation in Egypt (Exodus 12:3), is said to have fallen on the Sabbath (s. b. Sabb. 87b)." Moreover, the haftarah read on this day, namely Malachi 3:4-24, mentions the Messianic redemption. The choice of this specific haftarah as an additional divine service reading alongside the weekly Torah portion expresses the popular belief that the Messianic redemption of Israel would occur in the same month as the Exodus from Egypt.“

Note: The haftarah is a series of selections from the books of Nevi'im ("Prophets") of the Hebrew Bible (Tanakh) that is publicly read in synagogue as part of Jewish religious practice.

The English-language Wikipedia page also notes under the heading Special Shabbat, Shabbat HaGadol: 

„Shabbat HaGadol ("Great Shabbat" שבת הגדול) is the Shabbat immediately before Passover. The first Shabbat HaGadol took place in Egypt on 10 Nisan five days before the Israelite Exodus. On that day, the Israelites were given their first commandment which applied only to that Shabbat, "On the 10th day of this month (Nisan)... each man should take a lamb for the household, a lamb for each home (Exodus 12:3). There is a special Haftarah reading on this Shabbat of the book of Malachi. Traditionally a lengthy and expansive sermon is given to the general community in the afternoon.

Various reasons are given for the name of this Shabbat:

1. The Midrash Rabbah states: “When they (the Jewish people) set aside their paschal lamb on that Shabbat, the first-born gentiles gathered near the Israelites and asked them why they were doing this. The following was their response: “This is a Pesach offering to God who will kill the firstborn Egyptians.” They (the firstborn) went to their fathers and to Pharaoh to request that they grant permission to send the Jewish people free – but they refused. The first-born then waged a war against them and many of them (the Egyptians) were killed. This is the meaning of the verse (Psalms 136:10): “Who struck Egypt through its first born; for His kindness is eternal”.

2. The Tur states: The lamb was the Egyptian deity. Many Jews, after 210 years of immersion within Egyptian civilization, had also adopted this animal as their god. When God commanded that a lamb be set aside and tied to the bed for four days in anticipation of sacrifice, the Jewish people abandoned their idolatrous practice and courageously fulfilled this mitzvah in the eyes of the Egyptian people, thereby demonstrating their complete trust and faith in God. Nothing could have been more abominable to the Egyptians, for their god was to be slaughtered. Nevertheless, miraculously the Egyptians were unable to utter a word or lift a hand. They watched helplessly as their god was being prepared for slaughter. This miracle was a great miracle (nes gadol) and gives this Shabbat its name...

4. The Hatam Sofer writes: On this day [Sabbath, Nisan 10] the Jewish people fully ‘returned’ (Teshuvah) to their commitment and faith in God (as explained in reason #1). God is called gadol. Therefore, the Jewish People who embraced and subjugated themselves to God earned the title gadol as well...“

And the French Wikipedia page also says it outright:

„Shabbat HaGadol (Great Shabbat, Hebrew: שבת הגדול) is the name given to the Shabbat before the holiday of Pesach on the 14th of the month of Nisan. The first Shabbat HaGadol is celebrated in Egypt, before the Exodus from Egypt. On the 10th of Nisan, the Hebrews receive the commandment exclusive to this week: to take the Passover lamb. (see, Exodus 12:3). One of the reasons for the name Shabbat HaGadol is related to the Haftarah read on this Shabbat, from Malachi 3:235: Now I will send you Elijah the prophet before the day of the Lord comes, a great and dreadful day.“ 
[Original French: „Le Shabbat HaGadol (Grand Shabbat, en hébreu: שבת הגדול) est le nom donné au Shabbat qui précède la fête de Pessa'h, le 14 du mois de Nissan. Le premier Shabbat HaGadol est célébré en Egypte, avant l'Exode hors d'Égypte. Le 10 du Nissan, les Hébreux reçoivent le commandement exclusif à cette semaine: prendre l'agneau pascal. (voir, Exode 12:3). Une des raisons de l'appellation de Shabbat HaGadol est liée à la Haftarah lue en ce Shabbat, tirée de Malachie 3:23: Or, je vous enverrai Elie, le prophète, avant qu'arrive le jour de l'Eternel, jour grand et redoutable.“]

This is also the opinion of the JewishEncyclopedia:

„SHABBAT HA-GADOL ("The Great Sabbath"): The Sabbath preceding Passover. The designation "great" for this Sabbath is mentioned by Rashi (11th cent.), and is due to the great miracle of the Sabbath that preceded the Exodus, as related in the Midrash..., the 10th of Nisan in question was a Sabbath (Seder 'Olam R. V.; Mek. p. 46b; Pesiḳ. R., ed. Friedmann, p. 78a).“

The Israeli website AISH, which focuses on Jewish wisdom, names the Sabbath (10th of Nisan) as the day of separation and Thursday (15th of Nisan) as the day the people went out. Under the title "THE EXODUS TIMETABLE" it reads:

„The Talmud teaches that the day the Jews left Egypt -- the 15th of the month of Nissan -- was a Thursday, and the 10th of the month was the previous Shabbat.“

In 2020, the inaccurate Jewish calendar (originated in the 4th century AD) and God's exact astronomical calendar fell on the same days. Thus, every Christian can find this great weekly Sabbath (Shabbat ha-Gadol) on the 10th of Nisan and the 14th of Nisan (day of the slaughter of the lambs) on a Wednesday. The "first Sabbath" mentioned by Mark (Mk 16:9; the day of Jesus' resurrection) then always falls on the 17th of Nisan. Incidentally, this sequence of days is very common in the Jewish calendar and occurs about every third year. Rabbi Lazer (Eliezer Rafael) Brody mentions this Shabbat ha-Gadol in 2020 with the following words:

„Shabbat HaGadol: The main requirement for our redemption from slavery in Egypt was to overcome our fear of fulfilling Hashem's commandment... Shabbat Hagadol, the "Great Shabbat", commemorates the Shabbat before our people left the land of Egypt. That year, Shabbat fell on the 10th of Nisan, 4 days before the Passover sacrifice was to be slaughtered on the afternoon of the 14th of Nissan. Every Jewish family was commanded to tie ram lamb to their bedpost 4 days before the first Passover and make sure the sacrificial animal was in perfect condition.“  Source  

Note: HaShem (Hebrew translated 'the name') is a common name for God in Judaism because they were afraid to speak out God's name.

Now if the 10th Nisan was a Sabbath at the time of the Exodus, it is clear that the 14th Nisan had to be a Wednesday. There is nothing extraordinary about that; it happens very often in the Jewish calendar, about every third year. And the Jewish calendar was never designed so that a 14th Nisan could not fall on a Sabbath, because the lambs had to be slaughtered on a 14th of Nisan even if it fell on a Sabbath. See the chapter: Passover Lamb on the Sabbath, the 14th of Nisan.

The Hebrew4Christians website, like many other sources, says that the 10th of Nisan at the time of the Exodus was a Sabbath and the day of the Exodus (15th of Nisan) was a Thursday:

„According to the Talmud, the Exodus from Egypt occurred on Thursday, Nisan 15th, thus making the 10th of that month a Shabbat. It was on this great Shabbat that the LORD commanded the families of Israel to obtain a lamb for sacrifice and to bring it to their homes. This was to be Korban Pesach – the Passover lamb – to be sacrificed on Nisan 14th.“

Ari Z. Zivotofsky (JewishWorldReview) is even more explicit in his words. He writes on Friday, March 26, 1999 (Nisan 9, 5759), that is, in 1999, when the 10th of Nisan was again on a Sabbath:

„THE SABBATH IMMEDIATELY PRECEDING PASSOVER (March 27th, this year) is a distinguished one. It bears an impressive title and a unique set of liturgical and ritual practices. Known as Shabbat Hagadol -- The "Great" or "Big" Sabbath --- it can precede the holiday by as much as seven days.The year the Jews left Egypt, Passover, the 15th of the month of Nissan, occurred, according to tradition, on a Thursday. Thus, the 10th of Nissan was on a Shabbat. It was on that day that each Jewish family selected the Paschal Lamb that would be used at the seder. Since the Egyptians worshipped sheep this was a daring and risky action. A Great miracle occurred and the Egyptians remained passive. Thus, in commemoration of this Great miracle that occurred on the Sabbath before Passover , we observe the Sabbath before Passover as the Great Sabbath... The Chizkuni and others commentaries have suggested that the day was Great since, for the first time in our history, the Jews carried out a Divine commandment - the taking of the Paschal lamb - as a nation. Similarly, when a Jew matures and becomes obligated in the fulfilling commandments as a bar or bat mitzvah s/he is referred to as a Gadol - as in Shabbat hagadol.“

The well-known Jewish source Chabad (Eliyahu Kitov) also reports exactly the same fact:

„What is Shabbat Hagadol. The Shabbat which precedes Passover is called Shabbat haGadol, the Great Sabbath, for many and varied reasons, as we shall explain below. There are also many special customs associated with this Shabbat. It was in Egypt that Israel celebrated the very first Shabbat Ha-Gadol on the 10th of Nissan, five days before their redemption. On that day, the Children of Israel were given their first commandment which applied only to that Shabbat, but not to future generations: On the 10th day of this month [Nissan]... each man should take a lamb for the household, a lamb for each home (Exodus 12:3)... This mitzvah of preparing a lamb for the Passover offering four days before it was to be brought, applied only to that first Passover in Egypt, and the Torah does not tell us that we must continue to do so before every future Passover. Nevertheless, the people continued to do this to make sure that their lambs had no blemishes which would preclude their being sacrificed. Many miracles were performed for the Children of Israel on this first Shabbat haGadol. The Torah commanded them to take their lambs and tie them to the bedpost. When they did so, their Egyptian neighbors saw this and asked: "What is the lamb for?" The Children of Israel answered: "It is to be slaughtered as a Passover sacrifice as G‑d has commanded us." The Egyptians, for whom the lamb was a deity, gnashed their teeth in anger but could not utter a sound in protest. Many other miracles as well were performed in connection with the Passover offering, we therefore refer to this day as Shabbat haGadol.

Why We Celebrate Shabbat Hagadol instead of the 10th of Nissan [i.e., when in the Jewish calendar the 10th of Nisan falls not on the Sabbath but on another day of the week]: Why do we commemorate the miracle on the Shabbat before Passover rather than on the 10th of Nissan, the date on which it actually took place? We see that the Torah itself mentions only the date rather than the day of the week. It is because the miracle is closely connected to Shabbat. The Egyptians were aware that the Children of Israel observed Shabbat and did not busy themselves tending animals on that day, so when the Egyptians saw them taking lambs and binding them to their bedposts on Shabbat, they were surprised and decided to investigate what was happening. The Children of Israel were in great danger when they were confronted and were saved only by virtue of a miracle. We therefore commemorate this miracle on Shabbat rather than on the 10th of the month of Nissan. Moreover, had it not been Shabbat, the Children of Israel would not have needed a miracle to save them. They would have been able to deceive the Egyptians by diverting their attention or making up some kind of explanation. On Shabbat, however, they would not do so, for, as our Sages said, "Even an ignorant man will not tell lies on Shabbat." Thus, we see that they were endangered because of their observance of Shabbat, and they needed a miracle to save them.“

And on to the 10th of Nisan (Chabad, Eliyahu Kitov):

„Other events which took place on the 10th of Nissan are forever associated with this date. On the 10th of Nissan, after thirty nine years in the desert the virtuous Miriam died. Her passing deprived Israel of one of the three benefactors who sustained them in the desert: Moses, Aaron, and Miriam... When Miriam passed away, the waters in the well ceased:"And Miriam died there and was buried there. And there was no water for the congregation... (Numbers, 20:1,2)". The day of Miriam's passing became a fast day for all generations, in memory of this righteous woman. A year later, the day was again marked by a significant event but this time by a joyous one. On the 10th of Nissan, the Jordan River was divided for Israel and its waters rose up as if they were a wall and as our ancestors emerged from the Jordan to take possession of the Chosen Land, they trod for the first time on the holy soil. Among them were many who had come out of Egypt to whom the decree: "In this wilderness they shall perish (Numbers, 14:35)" did not apply: the entire tribe of Levi, those of all the tribes who were either children or elderly at the time of the decree, and many of the women.“

The Jewish website Misrachi Austria also knows the date of the separation of the very first lamb:

„The Sabbath before Passover is called Shabbat Hagadol - the Great Shabbat. On this Shabbat - that year on the 10th of Nissan - each head of family of the people of Israel, still enslaved in Egypt, chose a lamb to offer as the first Passover sacrifice on the 14th of Nissan. This posed an immanent danger to the Israelites, since the lamb was worshipped as a god in Egypt. Nevertheless, no harm was done to the children of Israel; G'dt prevented the Egyptians from intervening for a full four days, during which the lamb was first set aside and chosen for sacrifice.“

The FirstFruitsofZion website has the same content. Using the latest scholarly findings, ancient Jewish sources and extra-biblical literature, it presents a Messianic Jewish reading of the Bible and early Jewish Christianity. Here, too, the redemption and liberation of the people began as early as the 10th of Nisan:

„The Shabbat that comes before Passover is called Shabbat HaGadol. The Hebrew word gadol means “big” or “great.” So Shabbat HaGadol means, “the great Sabbath” or “the Sabbath of the great.”... The code of Jewish law gives a different explanation for the reading. The reason it gives is “because Shabbat HaGadol was the beginning of the redemption and the miracles.” This means that the reading is not just for practice. It’s more like a brief seder itself! We are reading because the miracles of Passover began on that day... Jewish tradition holds that in the year of the exodus from Egypt, the 10th day of the month of Nisan fell on Shabbat. The Israelites were aware that the Egyptians would be incensed by their lamb sacrifice and that they might be taking their lives into their hands, just as Moses said. Yet each of the Israelites took a lamb and tied it to the bedpost, in accordance with the command. This was the miracle that marked the beginning of redemption: When the Egyptians saw the Israelites taking their lambs, they asked them why they were doing this. The Israelites bluntly answered, “To slaughter as a Passover offering as HaShem has commanded us.” The Egyptians were grinding their teeth in anguish, but they were unable to do or say anything to stop the Israelites. This was the miracle that marked the beginning of redemption.“

There are still a great many sources from several centuries that repeatedly confirm the same days for the Exodus, namely Palm Sabbath (10th of Nisan), Wednesday (14th of Nisan, Preparation Day) and Thursday (15th of Nisan, High Sabbath).

There the Sunday worshippers have another big problem, because not only the NT, but also almost all Jewish literature states that the very first Passover lamb was set apart on a Sabbath (10th Nisan), slaughtered on a Wednesday (14th Nisan) and that the Exodus took place on a Thursday (15th Nisan). Everything coincides perfectly with the NT. We do not need these Jewish details, because the NT is clear enough, but this gives even more certainty.

Now, if there should be some Christians who still want to defend their beautiful unbiblical Good Friday and Easter Sunday and now say, "Wait a minute, but my translation talks about Resurrection Sunday," for them there is a detailed explanation with many literal translations from the Greek: see Resurrection on the Sabbath.

The Passion Week must be seen in its overall context between the 10th of Nisan (setting apart of the lamb) and the 21st of Nisan (end of the Passover feast): As with the first Passover lamb, redemption again took place at the full moon, exactly in the middle of this period:

In 2023, God's biblical calendar and the Jewish calendar fell on the same days, but this is usually not the case. The table below only shows the dates according to the Jewish calendar and is only intended to show that the 14th of Nisan very often falls on a Wednesday. The 10th of Nisan is then always on a Sabbath. 

Malachi 3-4 provides the perfect textual setting for the great weekly Sabbath (Shabbat ha-Gadol). It is a preparation for great events that will take place and a reference to the twofold appearance of the Messiah:

Mal 3:1-24: „Behold, I send my messenger, and he will prepare the way before me. And the Lord whom you seek will suddenly come to his temple; and the messenger of the covenant in whom you delight, behold, he is coming, says the Lord of hosts. 2 But who can endure the day of his coming, and who can stand when he appears? For he is like a refiner's fire and like fullers' soap. 3 He will sit as a refiner and purifier of silver, and he will purify the sons of Levi and refine them like gold and silver, and they will bring offerings in righteousness to the Lord. 4 Then the offering of Judah and Jerusalem will be pleasing to the Lord as in the days of old and as in former years. 

5 “Then I will draw near to you for judgment. I will be a swift witness against the sorcerers, against the adulterers, against those who swear falsely, against those who oppress the hired worker in his wages, the widow and the fatherless, against those who thrust aside the sojourner, and do not fear me, says the Lord of hosts.

Robbing God

6 “For I the Lord do not change; therefore you, O children of Jacob, are not consumed. 7 From the days of your fathers you have turned aside from my statutes and have not kept them. Return to me, and I will return to you, says the Lord of hosts. But you say, ‘How shall we return?’ 8 Will man rob God? Yet you are robbing me. But you say, ‘How have we robbed you?’ In your tithes and contributions. 9 You are cursed with a curse, for you are robbing me, the whole nation of you. 10 Bring the full tithe into the storehouse, that there may be food in my house. And thereby put me to the test, says the Lord of hosts, if I will not open the windows of heaven for you and pour down for you a blessing until there is no more need. 11 I will rebuke the devourer for you, so that it will not destroy the fruits of your soil, and your vine in the field shall not fail to bear, says the Lord of hosts. 12 Then all nations will call you blessed, for you will be a land of delight, says the Lord of hosts.

13 “Your words have been hard against me, says the Lord. But you say, ‘How have we spoken against you?’ 14 You have said, ‘It is vain to serve God. What is the profit of our keeping his charge or of walking as in mourning before the Lord of hosts? 15 And now we call the arrogant blessed. Evildoers not only prosper but they put God to the test and they escape.’”

The Book of Remembrance

16 Then those who feared the Lord spoke with one another. The Lord paid attention and heard them, and a book of remembrance was written before him of those who feared the Lord and esteemed his name. 17 “They shall be mine, says the Lord of hosts, in the day when I make up my treasured possession, and I will spare them as a man spares his son who serves him. 18 Then once more you shall see the distinction between the righteous and the wicked, between one who serves God and one who does not serve him.

The Great Day of the Lord

4:1-5: „For behold, the day is coming, burning like an oven, when all the arrogant and all evildoers will be stubble. The day that is coming shall set them ablaze, says the Lord of hosts, so that it will leave them neither root nor branch. 2 But for you who fear my name, the sun of righteousness shall rise with healing in its wings. You shall go out leaping like calves from the stall. 3 And you shall tread down the wicked, for they will be ashes under the soles of your feet, on the day when I act, says the Lord of hosts.

4 “Remember the law of my servant Moses, the statutes and rules that I commanded him at Horeb for all Israel.

5 “Behold, I will send you Elijah the prophet before the great and awesome day of the Lord comes. 6 And he will turn the hearts of fathers to their children and the hearts of children to their fathers, lest I come and strike the land with a decree of utter destruction.”“

Most Christians only know Palm Sunday, which is rare, but they do not know Palm Sabbath, which can often be observed in the Jewish calendar, for example in the years: 2020, 2023, 2026, 2027 and 2030. Here is a current example from the Jewish calendar and God's calendar (e.g. TorahCalendar):

Since most Christians do not want to have anything to do with the biblical feast days of God, they have turned this great Sabbath of the 10th of Nisan (Shabbat ha-Gadol) into a Lazarus Saturday, namely the day before the Catholic Palm Sunday, which is then followed by Easter Sunday and finally Pentecost Sunday. The Sabbath was made into Sunday again and again, what God thinks about it, that interests the fewest Christians. They prefer to follow old traditions, most of which originated in a pagan environment and were absorbed into Christianity over time. Therefore, in modern Bible translations, the biblical Sabbath had to be transformed into an unbiblical Sunday (see the chapter Old Bibles and the Resurrection Sabbath). 

Wikipedia writes about this:

"Lazarus Saturday" in the Orthodox churches is the Saturday before Palm Sunday. In the Gospel of John, the raising of Lazarus by Jesus is understood as a foreshadowing of his own resurrection and, at the same time, as the main reason for his crucifixion (John 11:45-53). Therefore, starting from the Holy Land, there was a Lazarus commemoration on Palm Sunday, the beginning of the Holy Week, or on the Saturday before. On Saturday a Lazarus procession from Jerusalem to Bethany takes place since the 4th century. This pre-Easter Lazarus commemoration has been preserved in the Orthodox churches as Lazarus Saturday.“

Since the Catholic (Gregorian) calendar calculates its feast days quite differently than God's calendar, so in the vast majority of years not even the correct Saturday before the biblical Passover is celebrated, but a false Saturday, which now has nothing to do with the 10th of Nisan.  

Even worse than the Orthodox churches are the Seventh-day Adventists. They believe the dead Ellen White (who adopted the Catholic teachings of Good Friday and Easter Sunday) more than the living Jesus who speaks of the Sabbath. Adventists also do not know what the "first Sabbath" (Mark 16:9) is, they only know the Pope's first Sunday of Advent. They do keep the Sabbath, but make Jesus a liar who supposedly would not have fulfilled the sign of the Messiah ("3 days and 3 nights"). What good is the Sabbath if they pervert the Word of God? Will the Sabbath save them or Jesus, whom they do not believe? So it is not surprising that Adventists call the false Sabbath the "great Sabbath," namely the Sabbath between Good Friday and Easter Sunday. They call it Easter Sabbath or Holy Saturday, openly admitting that they do not follow God's biblical calendar but the Pope's non-biblical calendar (Gregorian calendar) with its own feast days. These usually have a pagan origin and were only subsequently given Christian elements.

For Adventists, it is the Sabbath of Disappointment because the Lord died and was buried (supposedly on Friday) and was not resurrected until the day after (their Easter Sunday). FALSE, the biblical Passover feast already began with the separation of the Passover lamb on the 10th of Nisan and only this day of the announcement of the deliverance and miracles is the great Sabbath, the Shabbat ha-Gadol. On the other hand, the 17th of Nisan (again a Sabbath after 7 days) was the day of Jesus' resurrection, only this is written in the basic Greek text (Interlinear Bible) and in many correct Bible translations worldwide. The Jews, however, would never call this Sabbath a Great Sabbath or the Resurrection Sabbath because they rejected Jesus and even mocked him as a supposed "failed Messiah" who was not supposed to have been resurrected at all. But soon, in the Tribulation, they will realize their mistake, just like the Adventists too, who twist the Word of God (the most precious thing we humans have here on earth) just to be able to run after a woman (Ellen White).
