I have seen the notion passed about, regarding a thirteenth month in scripture. I see many people say things such as “there is no thirteenth month in the scriptures”. So this was where I decided to look for it, if it existed or if it did not.
Now I want to be clear. Even if we do find the thirteenth month in scripture, I do not believe it would have always been this way. The main reasons I say this is because of the time of trouble spoken about in Daniel and Revelation. They speak of “time, times and half a time”, which we see is 360 + 720 + 180 or 1260 days or 42 months. 42 months. That is 1260 days / 42 months = 30 days per month.
So if we see this, why would we even entertain the thought of a thirteenth month right?
Think of what occurs in a divorce. One person in a relationship of two, leaves that relationship because of something which the other person has done which can no longer be tolerated.
Part of what He gave us was His appointed times. His Sabbaths, His new moons, His feasts. These were the times we were able to spend with the Father. But we were unfaithful, and hence they were removed.
A certificate of divorce was given. It is like Yahuwah picked up His home (which is His temple and His appointed times) and moved it such that it could no longer be found.
We see this in Hosea 2
Hosea 2:2,9-11
2 “Bring charges against your mother, bring charges;
For she is not My wife, nor am I her Husband!
Let her put away her harlotries from her sight,
And her adulteries from between her breasts;9 “Therefore I will return and take away
My grain in its time
And My new wine in its season,
And will take back My wool and My linen,
Given to cover her nakedness.
10 Now I will uncover her lewdness in the sight of her lovers,
And no one shall deliver her from My hand.
11 I will also cause all her mirth to cease,
Her feast days,
Her New Moons,
Her Sabbaths—
All her appointed feasts.
Think about how the Father would remove the appointed times from the people. He would have to make it so they could not be found. He would need to modify time the way we know it. And this was done in the days of Hezekiah when the sun moved backward in the sky, the earth slowed. The solar year then became longer which also made the lunar year shorter at the same time. No longer would the people be able to find the appointed times.
So what effect would this have upon our year as we currently know it? The number of days in a solar year moved from 360 to 365.25 and the number of days in a lunar year moved from 360 days to 354.37 days. Together they still add up to 360 days per year (365.25 + 354.37/2 = ~720/2 = 360 days per year)
Before we continue with the prophecy spoken about in Hosea 2, I wanted to pause for a moment and look at what we currently have time wise. We have a solar year 0f 365.25 days and a lunar year of 354.37 days. We have a scriptural year however which changes between 354 and 384 days. Why? To keep the calendar in line with the growing seasons every three to four years an extra month of 30 days needs to be added to the calendar. This keeps the lunar calendar in line with the solar calendar. They both move along together. Is it the way Yahuwah wanted it? No. I do not believe so. It is because we had rejected him and thus He rejected us. Sin cannot live with Yahuwah. The two are not compatible in the same way Light is not compatible with darkness. It is one or the other. Pure or impure.
When we read the book of Ezekiel, specifically chapters 1 – 8, we see something many do not always see. Let’s draw out a timeline by first collecting the dates from scripture.
In Ezekiel 1:1-2 we are told that Ezekiel received a vision from Yahuwah on the 5th day of the 4th month, in the 5th year of king Jehoiachin’s captivity.
Ezekiel 1:1-2
1 Now it came to pass in the thirtieth year, in the fourth month, on the fifth day of the month, as I was among the captives by the River Chebar, thatthe heavens were opened and I saw visions of Elohim.
2 On the fifth day of the month, which was in the fifth year of King Jehoiachin’s captivity.
So we start at the 5th day of the 4th month. Then in Ezekiel 3 we find that Ezekiel dwelt by the river Chebar for 7 days.
Ezekiel 3:15
15 Then I came to the captives at Tel Abib, who dwelt by the River Chebar; and I sat where they sat, and remained there astonished among them seven days.
This brings us to the 12th day of the 4th month. Then in Ezekiel 4:1-11 he is given instructions by Yahuwah to lay on his left side 390 days and when he accomplishes this he is to then lay on his right side 40 days; equaling a total of 430 days (A day was to represent a year for Israel and Judah for their inequity). In Ezekiel 8 we find that upon the 5th day in the 6th month of the 6th year he is sitting.
Ezekiel 8:1
1 And it came to pass in the sixth year, in the sixth month, on the fifth day of the month, as I sat in my house with the elders of Judah sitting before me, that the hand of Yahuwah Elohim fell upon me there.
So let us look at this 430 day count when we use a calendar with 12 months in it only. We are going to assume 30 days in the calendar as well, even though today we have 29, and 30 day months in the Gregorian calendar.
Month # = day count
4 – (from day 12) = 18
5 = 30
6 = 30
7 = 30
8 = 30
9 = 30
10 = 30
11 = 30
12 = 30
1 = 30
2 = 30
3 = 30
4 = 30
5 = 30
6 = (to the 5th day) 5
Total = 413 days
The problem here is that we still have another 17 days to go until we meet the 430 days. It is hard to imagine that Ezekiel would have disobeyed Yahuwah. So what is the solution? Let’s look at the calendar when we use a lunar month which changes between 29 and 30 days as we have today, and when a 13th month is added. The thing I find interesting is that this calendar represents a people living in sin as well. It is not pure.
Month # = day count
4 – (from day 12) = 18
5 = 29
6 = 30
7 = 29
8 = 30
9 = 29
10 = 30
11 = 29
12 = 30
13 = 29
1 = 30
2 = 29
3 = 30
4 = 29
5 = 30
6 = (to the 5th day) 5
Total = ~ 435 – 436 days (depending upon whether you start your count with 29 or 30 days in the first month).
This count of 430 days is only possible when one adds in a thirteenth month into the calendar. A purely solar only calendar does not work. So yes. We do find a 13th month in scripture, but it appears when Israel is in Sin.
In the rest of Hosea 2 the prophecy continues:
Hosea 2:14-23
14 “Therefore, behold, I will allure her,
Will bring her into the wilderness,
And speak comfort to her.15 I will give her her vineyards from there,
And the Valley of Achor as a door of hope;
She shall sing there,
As in the days of her youth,
As in the day when she came up from the land of Egypt.
16 “And it shall be, in that day,”
Says Yahuwah,
“That you will call Me ‘My Husband,’
And no longer call Me ‘My Lord,’
17 For I will take from her mouth the names of the Baals,
And they shall be remembered by their name no more.
18 In that day I will make a covenant for them
With the beasts of the field,
With the birds of the air,
And with the creeping things of the ground.
Bow and sword of battle I will shatter from the earth,
To make them lie down safely.
19 “I will betroth you to Me forever;
Yes, I will betroth you to Me
In righteousness and justice,
In lovingkindness and mercy;
20 I will betroth you to Me in faithfulness,
And you shall know Yahuwah.
21 “It shall come to pass in that day
That I will answer,” says Yahuwah;
“I will answer the heavens,
And they shall answer the earth.
22 The earth shall answer
With grain,
With new wine,
And with oil;
They shall answer Jezreel.
23 Then I will sow her for Myself in the earth,
And I will have mercy on her who had not obtained mercy;
Then I will say to those who were not My people,
‘You are My people!’
And they shall say, ‘You are my Elohim!’ ”
So we see a people no longer using a pagan calendar with other gods whom they walk after. Rather we see that time is restored as the days are shortened. We again have a calendar following His appointed times and scripture says that this is done for the sake of the elect, His 144,000 – the ones who follow His commandments.
Matthew 24:22
22 And if those days had not been cut short, no human being would be saved. But for the sake of the elect those days will be cut short.Mark 13:20
20 And unless Yahuwah had shortened those days, no flesh would be saved; but for the elect’s sake, whom He chose, He shortened the days.
Yahuwah Bless.
The Calendar of Scripture 
This is interesting.. if the days of the earth are shortened, as prophecy says, there will be more days in a solar year. So a solar year will be somewhat longer than 365 days. This is not the direction we need to go in to get back to a 360 day year.. so there needs to be another change somehow, like changing the orbit of the earth so it would circle the sun in less days.
Shortening the days would in fact make the lunar cycle have more earth days. So this would be in the right direction to increase a lunar month from 29.54 days to the required 30 days, and for a year of 360 days to contain exactly 12 lunar periods. What do you think Yah will change to make the year have 360 days again?

Hi Scott,
I appreciate your perspective, but I must disagree with your conclusion that Scripture only supports a 12-month calendar. Your claim that canonical Scripture, Enoch, Jubilees, and the Dead Sea Scrolls only recognize 12 solar months is not entirely accurate.
1. The Necessity of a 13th Month in a Lunar Calendar
The Hebrew calendar has always been based on lunar cycles. A lunar year consists of approximately 354 days, while a solar year is about 365.25 days. Without intercalation (the addition of an extra month), the seasons would drift, causing feasts like Passover (which must be in the spring) to shift into winter over time. The ancient Hebrews used observational methods (such as the barley harvest) to determine whether a 13th month was necessary to keep the calendar in alignment.
The Dead Sea Scrolls, particularly the Temple Scroll, show that the Qumran community favored a solar calendar, but this does not mean the biblical calendar was strictly solar. If the biblical calendar had been purely solar, then the lunisolar intercalation practice of ancient Israel makes no sense.
2. Evidence of a 13th Month in Scripture
The Torah itself doesn’t explicitly spell out the mechanics of intercalation, but it gives strong hints:
Ezekiel’s 430-Day Prophecy (Ezekiel 4:4-6 & 8:1)
When counting the days in Ezekiel’s prophecy, as shown in the post above, a 13th month is mathematically required to complete the prophecy correctly. A purely solar-based 12-month calendar does not allow for the full count of days needed.
1 Kings 12:32-33 – King Jeroboam instituted a feast “in the eighth month, on the fifteenth day of the month, like the feast that was in Judah.” If there were no adjustments to the calendar, why does Scripture explicitly point out that this was a different timing than the standard festival cycle? It suggests a flexible calendar system.
Esther 3:7 – The reference to “the twelfth month, which is the month of Adar” suggests that there was an expectation of potential variations, as Jewish tradition identifies Adar II (a 13th month) in intercalary years.
3. First Enoch and Jubilees are Not Universally Accepted
While you mention 1 Enoch and Jubilees, these texts were not considered canonical by the majority of Jewish or Christian traditions. Even so, while the Book of Enoch promotes a 364-day solar year, this does not reflect the actual practice of ancient Israel, as it contradicts the lunar-based New Moon observances mandated in Torah (Numbers 10:10, Psalm 81:3). Additionally, the Dead Sea Scrolls show competing calendar views, meaning there was no single, universally accepted system.
4. Matthew 24:22 and Mark 13:20 – Days Will Be Shortened
Yahushua (Jesus) Himself mentioned that the days would be shortened for the sake of the elect. This suggests a divine adjustment to time, aligning with the idea that the perfect 360-day year was altered post-flood and after Hezekiah’s sign (2 Kings 20:8-11), leading to the need for intercalation in the current calendar.
Conclusion
The biblical calendar is clearly lunisolar. The Torah mandates observational methods for determining months, which means intercalation was required to keep feasts in their proper seasons. Ezekiel’s prophecy mathematically requires a 13th month to be accurate, proving that such adjustments did occur.
Rather than dismissing these points as “hogwash nonsense,” I encourage you to take a closer look at the textual and historical evidence that suggests otherwise.
Blessings,
Robert

the Geneva Bible shows 13 months at 28 days which equals 364 days. Also the earth is immovable and the sun and moon are in the firmament and they move, not the earth as it is written.
LikeLike
The word you see as immovable in English comes from the Hebrew word mot. The old Testament was written in Hebrew not English and the words were translated into the closest word in English, however this does not always give a true sense of the meaning. The meaning of mot is to totter, shake, slip
(Qal) to totter, shake, slip
(Niphal) to be shaken, be moved, be overthrown
(Hiphil) to dislodge, let fall, drop
(Hithpael) to be greatly shaken
The words before this says that the world is established. It is securly determined.
This does not mean the world does not move. But it is fixed in it path that has been ordained by Yahuwah and it shall not deviate out of that path. You need to be careful in what you read and understand as Hebrew is not as literal as English. The meaning of each word is greater than just the parts unlike English where the parts have no meaning but the word itself does.
Regarding the Geneva Bible. Please provide scripture.

question: where and how did you immediately jump to sin and divorce as the solution. You described your view well but if he never changes and we observe the feasts etc why would we adjust here?
Also historically wise could it not also be safe to assume that at this point in time already of Hosea and Ezekiel that they’re using a Rabbinical calendar? Hence why Ezekiel’s timeline may line up with that? Especially if his prophecy was to those current day people?

You need to understand the context with which this was written. It is asking WHY we have 13 months in some lunar years when the calendar which God uses has only 12. And that is where the divorce comes in.
We are speaking of time. How do you change the time such that your appointed times are no longer being abused by the people? For that is what was occurring. Hosea 2:2,9-11 highlights this very link between marriage and time.
Hosea 2:2,9-11
2 “Bring charges against your mother, bring charges;
For she is not My wife, nor am I her Husband!
Let her put away her harlotries from her sight,
And her adulteries from between her breasts;
9 “Therefore I will return and take away
My grain in its time
And My new wine in its season,
And will take back My wool and My linen,
Given to cover her nakedness.
10 Now I will uncover her lewdness in the sight of her lovers,
And no one shall deliver her from My hand.
11 I will also cause all her mirth to cease,
Her feast days,
Her New Moons,
Her Sabbaths—
All her appointed feasts.
So He never changes. Correct. But he changed OUR day length so OUR time would no longer be a marriage with HIS time. That is the point the article makes.

Wow! You say all that and still fall to a wrong conclusions. You never pointed to scripture where God tells them they have 30 day months for 12 months and they do that for 6 years in a row and on the seventh year they have add a (13th) thirteenth month and they where to rest their land. Wasn’t that a point when God punished them after forgiving them 7×70 times.
What language do you speak? Is it English, Greek, or Hebrew maybe all three?
Who is Yahweh?
Who is Yahushua?
There both Jesus right? I’m not asking a question here. When I was a kid I never heard preachers saying these names. It’s like a fad and people blindly follow. God gives us our language and mine is English, so I speak, pray, and think in English. Most English speaking Christians don’t know Hebrew or Greek and they take your world for what these names mean. Most all names in the Bible refers to the Lord God Almighty. The Father and the Holy Ghost rarely speak the Holy Ghost more then the Father and the Father only spoke to or at mankind never a two way conversation.

Hi David,
I appreciate you taking the time to read through the article and share your thoughts. You’ve raised some good questions — particularly about the thirteenth month and whether Scripture supports it.
You’re right that the Torah doesn’t contain a direct verse saying “there shall be twelve months of thirty days each”. Instead, the pattern is revealed through observation of Yahuwah’s creation — the luminaries He set in place to govern appointed times (Genesis 1:14).
When I spoke of the 30-day prophetic months in Daniel and Revelation, that referred to the restored, perfect calendar that existed before the fall of time itself — when the year was 360 days (Genesis 7:11 and 8:3–4 show the 150 days between the 17th day of the 2nd month and the 17th of the 7th month — five exact 30-day months). The thirteenth month arises only after the alteration of time — after sin fractured the harmony between sun and moon.
As for the use of the names Yahuwah and Yahushua, they are simply closer renderings of the Hebrew originals — not meant to create division or trend, but to honour their meaning: “Yahuwah is Salvation.” Whether someone says Jesus or Yahushua, the heart of worship matters most — but it is also valuable to return to the names that carry His covenant identity and purpose.
The original language is so different to English. In English each letter contain no meaning. It is just a sound. Together these letters contain meaning. But the original language is not like that. Each letter contains meaning and it is these letters that provide the overall meaning. So Yahushua in English is just a name, but in Hebrew it translates into God Saves. You just don’t get that in English. In fact its not just His name, but the entire bible.. each word has a meaning made of of the letters the word consists of.
Thank you again for engaging thoughtfully. My hope isn’t to argue, but to help all of us see how deeply Scripture ties time, worship, and obedience together.
Blessings,
Robert-Aaron
