Qumran / Jerusalem Calendar Disputes


As many of you know, for the past three decades, I’ve been faithfully observing the rabbinically approved sighted moon (lunar) calendar.

Because of all the stuff going on in the world, I began to look closely at the story of Noach in Genesis 7, the prophetic End-Times chronology of Daniel chapters 9-12, and the prophetic numbers in the book of Yochanan’s Revelation, chapters 6-12.

In September of 2021, it was briefly brought to my attention, from the research of Dr. Michael Heiser, that the prophetic numbers found in the three biblical sources mentioned above; all are linked to a precise solar calendar of 12 months x 30 days each. Plus, there are four additional days added to the four seasons of change mentioned in Genesis 6 called חודשים (chodeshim) or to say loosely, “Headers,” leading us into each of the four biblical seasons - Summer (hot), Winter (cold), Seedtime (Spring), and Harvest (Fall).

While doing my research, I was shocked to find the same precise prophetic pattern of calculated time not only in Genesis 7 and in Daniel 9-12, but also in the End-Times chronology of Yochanan’s Book of Revelation chapter 12. So, I began digging even deeper to find out why all the prophetic chronology of time matches all across the Hebrew and Greek texts of the Bible from Genesis to Revelation, but ONLY when using a 364-day solar high-priestly Tzadok calendar. The sighted moon 354-384 day rabbinic lunar calendar NEVER produced the same consistent results with the solar calendar.

After some meticulous personal study and, I believe, Spirit-led convictions, I made a tough decision with my wife in September of 2021 to step into and practice the Tzadok high-priestly calendar of 364 days. Of course, one might ask the question, Why study the solar calendar by DOING IT? My answer: Because to judge the merits of the 364-day solar calendar accurately, I felt that I needed to do it from the inside and NOT merely talk about it from the outside. I'll have more to say about all of this in a future post.

I now want to share with you a small piece of my research to understand WHY I have made the switch.

If you have ever gone beyond doing a general surface read of the chronology of Yeshua’s death and resurrection Passover week, in the gospel narratives, you probably noticed what appears to be a lot of chronological inconsistencies. Significantly, this is very evident when comparing the Synoptic narratives (Matt, Mark, Luke) with the Gospel of John. Collectively, I have noticed over many years in reading the chronological gospel narratives that the Passover Week chronology from all four accounts doesn't add up; none of it makes any logical sense. The whole chronology comes across as very messy and confusing. BUT...

I recently detailed every statement from Yeshua’s Passover Week chronology in the gospel narratives. Then, I began to categorize each report according to the known calendar disputes in the middle to late Jerusalem Second Temple period from about 175 B.C.E. to about 90 C.E.

After some dedicated lengthy hours processing through all of the known calendar disputes referenced in the Dead Sea Scrolls, including 4Q324d, 4QMMT, the Book of Yovelim (Jubilees), amazingly, Yeshua’s Passover week chronology comes into full synchronization! I was truly surprised to see that all the gospel chronology problems just melted away!

For me, this was a clear sign that Yeshua and his disciples were on a totally different calendar! They were apparently DOING the Qumran Tzadok high-priestly solar calendar. In contrast, the Jerusalem Temple Sadducees, Pharisees, High Priests, and Scribes did the typical rabinically approved 354-384 day sighted lunations calendar.

Well, this discovery of the synchronized chronology of Yeshua’s Passover Week totally clinched it for me. Indeed, threading the gospel narratives into the Dead Sea Scrolls Tzadok Qumran Community solar calendar made all the chronological inconsistencies disappear totally!

Shortly, I'll be posting a series of PDF docs of my detailed research so that, if you are interested, you can go over my work and check it out for accuracy because I do firmly believe in accountability, one to another. Be looking for it soon.

Health and blessings to each of you in the coming months.

Yes, you are correct. The issue that still needs to be resolved is that of the “preparation day” narratives and the two back to back Sabbath's. I'm working on charting the chronology. Be patient. Thx!

“‘Also on the fifteenth day of the seventh month, when you have gathered in the fruit of the land, you shall keep the feast of the Lord for seven days; on the first day there shall be a sabbath-rest, and on the eighth day a sabbath-rest.” ‭‭Leviticus‬ ‭23:39‬ ‭NKJV‬‬ The feast of Sukkot specifically says there shall be a “Sabbath-rest” on the first and eighth days the Torah does not say this for the first and last day of unleavened bread.


I think one area of confusion is the night Yahshua had his Seder meal with His disciples was exactly when Lev 23:5 said that יהוה would have His meal as compared to when He would actually Passover His people. One is used as a noun the second a verb. Yahshua would have His meal a full 24 hrs prior to when His people would eat it. “On the fourteenth day of the first month at twilight is the Lord’s Passover.” ‭‭Leviticus‬ ‭23:5‬ ‭NKJV‬‬ The word for twilight is erev which is evening


Hi Avi May your adventure into the solar calendar bring you new insights in the Bible. Glad it’s you and not me. We had noticed there are conflicting dates but we haven’t the expertise to research. You often mentioned ( in the midst) so you are keeping with your teaching.

Thoughts lately. I think Jewish believers need to find their roots just as much as gentile believers need to find theirs. As in marriage two different people come together to produce life so Jews and Gentiles need to come together in a Godly harmony to produce life. Messianic groups we have fellowshiped with seem very influenced by the Western church and the messianic gentile church seem to be bent on…

At this stage for gentiles we need to get back to that 3rd and 4th century time frame and do a bit unpicking and I suppose it all started in the first as well. No wonder God has to give us a big kick. Still wondering how two “married men” can produce life or likewise woman We’re still trying to tell people that Yom doesn’t start at midnight Crumbs we have a long way to go.


The original Hebrews at Mt Sinai we’re expected to keep to keep the moedims with what was given in the Torah wouldn’t the information be contained there otherwise a just God cannot hold them accountable to keep them
