13th month     I’m still trying to find in the Bible where it mentions 13 months. Where do you find proof for this?

13th month     The Bible never provides an exact number of months for the biblical year. What it does provide is the method to begin the year and count each subsequent month. The Bible confirms that the first month of the biblical year is called “Abib.” Deuteronomy 16:1 states, “Observe the month of Abib, and keep the passover unto Yahweh thy Elohim: for in the month of Abib Yahweh thy Elohim brought thee forth out of Egypt by night.”

The word “observe” comes from the Hebrew shamar and means to guard. It also conveys the idea of watching. The word “month” derives from the Hebrew chodesh. Strong’s defines this word as, new moon and by extension, a month. Lastly, the word “Abib” is Hebrew and means, young ears of grain. Exodus 9:31 verifies that the grain spoken of is barley. It states that the barley was in the “ear” or Abib near the Passover observance (occurring on the 14th day of the first month, Lev. 23:5). Agriculturally, the wheat harvest begins in the third month, approximately two months after the beginning of the barley harvest.

These facts help in determining how to begin the biblical year. Deuteronomy 16:1 is literally commanding that we look for the new moon within the month of green ears. Agriculturally, Abib refers to when the barley enters the late dough stage, i.e., when the grain can be parched or roasted.

Therefore, Abib begins at the new moon crescent when there is barley in the dough stage or later. This occurs between March and April. Each subsequent month then begins with the sighting of the new moon crescent. Since there is an 11-day difference between the solar and lunar year, every 2-3 years a 13th month must be added to keep the seasons aligned. The Jews call this month Adar II. The Bible does not mention a 13th month.

The New Unger’s Bible Dictionary confirms this method, “The months began with the new moon, but the first month was fixed (after the Exodus and by the necessities of the Passover) by the ripening of the earliest grain, namely, barley.”

Additional evidence is found from the International Standard Bible Encyclopaedia, “…Abib is not properly a name of a month, but part of a descriptive phrase, ‘the month of young ears of grain.’ This may indicate the Israelitish way of determining the new year (Ex 12:2), the year beginning with the new moon nearest or next preceding this stage of the growth of the barley.”

Since Exodus 9:31 and 12:2 shows that the barley was in Abib before the new moon crescent, this is the pattern YRM uses to fix the month of Abib.

It’s important to note that in the 4th century, Hillel II changed the biblical calendar and transitioned from a calendar based on observation to calculation, including using the conjunction to begin the month and the autumnal equinox to begin the year. Since the autumnal equinox occurs in the fall, corresponding to the 7th Jewish month, the Jews count backwards to mark the first biblical month. Along the way, they also add their postponements, ensuring that days like Yom Kippur does not occur alongside of a weekly Sabbath. To ensure the alignment of the seasons, they also employ a 19-year cycle, adding a 13th month at intervals of 2-3 years.

Of course when Deu 16:1 was given there was no barley planted in the wilderness, it simply meant the greening of spring. They pretty much read Deu 16:1 as to observe the month of the spring. Before the Hillel II calendar was instituted the Sanhedrin calculated the Spring equinox, then calculated when the following new crescent moon would be seen and had the eye witnesses to confirm it. From there they declared the first month of the year. This is the method used 2000 years ago and apparently Yeshua or his talmidim had no issues with it. This year the… Read more »

No body in all the centuries that I have researched seems to have done the math about the calendars. If they would have, they would have discovered that the modern jewish calendar is off. It was never used in it’s current form in Biblical times. Since I’ve done the math, I’ve rediscovered that accurate Jewish calendar.

The calendar has been wrong from the first time man thought to change it. Adding postponements, changing it during the Babylonian captivity, then to make Rome feel better later on – it’s all wrong. The mere fact that you stated Hillel II changed it from observations (the way God intended it to be) to calculations is proof that the Jews have never learned that their ego will get them in trouble. Chosen? Yes. Disobedient? From beginning to end.
