The Scriptural Lunisolar Calendar

This Scriptural Calendar study shows how the lunisolar calendar works, and reveals the glory of its design.

Let’s start this study by remembering that Satan does not want you to know the truth about the Biblical calendar, and he has worked hard to provide different explanations, which serve to confuse people.

Many people teach that the Biblical calendar starts when the Jews site the crescent moon in Israel.

Some people teach that the new month starts with the full moon.

Many people teach that the lunisolar calendar dictates the months and Feast Days, but not the weekly Sabbaths.

But the truth is revealed in the many examples of Scripture which prove that the year and months begin with the dark conjunction of the moon, and that the Sabbaths fall on the 8th, 15th, 22nd, 29th of the Biblical month.

Note: We are not saying that the Sabbaths fall on the 8th, 15th, 22nd and 29th of the modern Gregorian calendar.

Some people object to the lunisolar sabbaths because they cannot keep them because of work obligations.

But that doesn’t not prove anything.  In fact, it points to the enemy who created the modern calendar, which has most people working during the week, so that they can’t observe the Sabbath days.

I believe that just as Messiah took the concepts of the law and made them more stringent; such as saying that hating someone is the same as being guilty of murder; or lusting after someone is the same as being guilty of adultery…

Messiah took the concept of the Sabbath to the next level.  He called us to be set-apart for Him every day.

The most important thing about the lunisolar Biblical calendar is being able to determine the Holy Feast Days.

The goal of this study is to give you a basic understanding of the calendar in a concise manner.  Links are provided at the bottom that have more detailed explanations.

To discern the truth, we have to follow the commands of Scripture; then see where those days fall on the Gregorian calendar.

Scripture declares that there are three types of days, not two; which invalidates the concept of a continuously-repeating 6 work day / 1 Sabbath day cycle.

Ezekiel 46:1 tells us that there are working days, Sabbath days and New Moon days.

Thus says the Lord GOD: “The gateway of the inner court that faces toward the east shall be shut the six working days; but on the Sabbath it shall be opened, and on the day of the New Moon it shall be opened.

1 Samuel 20 proves that the first day of the month is the New Moon Day.

David was not present at meal time on the New Moon Day and the second day of the month, and Saul asked why he was absent both yesterday and today.

And David said to Jonathan, “See, tomorrow is the New Moon, and I ought to sit with the sovereign to eat. But let me go, and I shall hide in the field until the third day at evening. 1 Samuel 20:5

And it came to be the next day, the second day of the month, that David’s place was empty. And Saul said to Jonathan his son, “Why has the son of Jesse not come to eat, either yesterday or today?” 1 Samuel 20:27

Numbers 29:1-6 describes the sacrifices that were commanded on the first day of the seventh month, on the New Moon Day.

And in the seventh month, on the first day of the month, you have a set-apart gathering, you do no servile work, it is a day of blowing the trumpets for you. And you shall prepare a burnt offering as a sweet fragrance to Yahuah: one young bull, one ram, seven lambs a year old, perfect ones, and their grain offering: fine flour mixed with oil, three-tenths of an ĕphah for the bull, two-tenths for the ram, and one-tenth for each of the seven lambs, and one male goat as a sin offering, to make atonement for you, besides the burnt offering with its grain offering for the New Moon, the continual burnt offering with its grain offering, and their drink offerings, according to their right-ruling, as a sweet fragrance, an offering made by fire to Yahuah.

More verses are provided that prove that the New Moon day is a third type of day on the A Repeating 6/1 Day Cycle Is InvalidLINK study.

The New Moon day is not a work day or a Sabbath day. It is the first day of the month, which interrupts the 6 work day / 1 Sabbath day cycle.

Looking back to Ezekiel 46:1, the east gateway would be open on the 1st day of the Biblical month, the New Moon day; and on the four Sabbath days of the month, which would fall on the 8th, 15th, 22nd and 29th of the month.  The gate would be closed on all of the work days.

Lunisolar Sabbath Ezekiel 46:1, the east gateway

The explanation of why the month starts after the the dark conjunction phase of the moon is explained in the When does a Biblical month start? studyLINK, but for now let’s just look at how the calendar is laid out.

  • The dark conjunction of the moon determines the new month.
  • The next day after the dark conjunction is the New Moon Day, the 1st day.
  • Then the seven day week begins, and the 8th day of the month is the Sabbath
  • The 15th day (the next Sabbath) is the full moon.
  • The 22nd is another Sabbath.
  • The last Sabbath of the month is on the 29th.
  • The next month begins with the next new moon, and the count of days begins again.

Once the New Moon Day is determined, we know the start of the month, and we know when the Sabbaths fall on the Gregorian calendar.

For example, as you can see below, if the New Moon Day (the 1st day of the Biblical Month) lands on a Thursday of the Gregorian calendar, then applying the every 7th day principle, the Sabbaths are going to fall on Thursday of that Biblical month.

Lunisolar calendar Sabbaths with Gregorian days listed

The six work days / 1 Sabbath day pattern is still kept on this calendar, but the New Moon Day proves that the six work days / 1 Sabbath day pattern is not a continuously-repeating cycleLINK, as most Saturday Sabbath people believe.

On this calendar, the Sabbaths are always in the same place, on the 8th, 15th, 22nd, and 29th of the Biblical month.

Some months have 29 days, others have 30 days; as the lunar cycle is 29.5 days. You simply look to see when the dark conjunction occurs to start the next month, to know if a 30th day will fall in the current month.

Some people say that this invalidates the lunisolar calendar, because the cycle always has to be a continuously-repeating 6 work day / 1 Sabbath Day cycle.

But there is no Scripture that declares that it has continuously repeated throughout history. There is no Jew who can prove that such a cycle exists and that it amazingly aligns with the 7th day on the pagan Roman Gregorian calendar.

And as we saw in the Ezekiel verse, Scripture defines a New Moon Day, which invalidate the continuous 6/1 day cycle.

Elohim setup the moon to keep His people in sync with the Sabbaths.

And Elohim said, “Let lights come to be in the expanse of the heavens to separate the day from the night, and let them be for signs and appointed times, and for days and years. Genesis 1:14

No matter where you are at on earth, you can observe the moon and know where you are at on the calendar. That is the brilliance and simplicity of Elohim’s design!

The first quarter 1/2 moon falls near the 1st Sabbath on the 8th day; the full moon falls near the Sabbath on the 15th day; and the last quarter 1/2 moon falls near the 3rd Sabbath on the 22nd day.

Lunar phases which dictate the Biblical calendar and sabbaths

Here is a link to an online tool which gives you a Biblical calendar, with the Sabbath Days and Feast Days, based on where you live:

Here is a PDF of the World Last Chance calendar until 2024 (based on Colorado time zone).  You can create your own on the WLC calendar by printing 99 months.  The only real difference for people in North America is the dawn and dust times of the Sabbaths and Feast days, which you can adjust from MST.

You can print 99 months worth of the WLC calendar, or if you have Adobe Acrobat you can save it as a PDF file.

Or you can access the lunar cycle calendar for your area at, and look up charts for each year for the next 20 years. You might want to print them out so they you have a hard copy, in case you can’t access the Internet in the days ahead.

Historical Witnesses:

Some people believe that the book of Enoch provides insight, others dismiss it.  Here are some passages from the book that affirm the dark conjunction New Moon:

And when the moon rises, one fourteenth part appears in heaven and on the fourteenth day the moon’s light becomes full. Enoch 78:6

And fifteen parts of light are transferred to her until the fifteenth day when her light is full. Enoch 78:7

And on the first day she is called the new moon, for on that day the light rises on her. Enoch 78:12

The knowledge of the calendar has resurfaced after being ignored for over 1500 years. Careful reading of the Scriptures, together with detailed study of history reveal that the the calendar used over 2000 years ago is not the same as today. The historical research reveals that Rome was responsible for enforcing the change.


Jews wrongly proclaim that the New Year starts when they sight the crescent moon in Jerusalem.

The modern Hebrew word for “New Moon” is chodesh (H2320), which is also translated as “month.” Chodesh appears in Scripture more than 270 times, yet it is not used even once to denote seeing something (i.e. the visible moon, the crescent, etc.). Rather, the Hebrew word signifying the physical, observable moon is yerach (H3391, H3393, & H3394). Yerach is translated 28 times as “moon” and 13 times as “month,” but is never used to signify the New Moon/month.

There is a Hebrew word for “crescent” – śaharōnîm (H7720). However, it is used exclusively in connection to heathen idolatry (Judges 8:21 & 26; Isaiah 3:18), and is never associated with the “New Moon” or even the “month.”

chodesh based on chadash; a primitive root; to be new; causatively, to rebuild:—renew, repair.

Day ends, new day begins. 11:59:59 – 12:00:00.

You can’t see the sliver until it’s 3-4% illuminated. The previous day doesn’t end at 2-3%. It ends at 0%. The leaves us with a gap.

If the Jewish notion is correct of a sliver moon marking the first day, which is at 3-4% illumination, the last day of the previous month end at 1-2% illumination. That is absurd.



The brilliance of the lunar-based monthly calendar is that no matter where you are on Earth, you can determine the start of the new month, and the weekly Sabbaths, based on the lunar cycle.

Using man’s creation of the International Date Line just adds confusion to this.

It can be Friday for a person on one side of the date line and Saturday for a person on the other side; yet they may only be a few miles apart, and are looking up at the moon or sun, rising and setting, at the same time.

So for one person it would be Friday and the other it would be the Saturday Sabbath.
