HEBREW CALENDARS AND LUNAR MONTHS

Moon

A Lunar Month is a period of time equal to the interval between two new moons.

The Hebrew Calendar contains 12 lunar months of alternately 29 and 30 days each. Nisan (Abib), as we are told in the
Bible, is the beginning of months in a year. (Ex. 12:2, Ex. 13:4, Deut. 16:1, Esther 3:7). To keep the holy days in their
appropriate cycle it becomes necessary to insert an extra month into the Hebrew (lunar) year. This "leap month"- called
Adar II, is added seven times in a nineteen-year cycle in order to maintain a balance between the Hebrew (Lunar) year
and the Gregorian (Solar) year.

*Nisan is used after Adar II.

**Abib (The 1st month of the ancient Hebrew calendar corresponding to Nisan) is used after Adar.

***Adar II is added when there is a "leap month" in the Hebrew (lunar) year. It is added to the Hebrew (Lunar) Calendar
when there are 13 New Moons in the Gregorian (Solar) year.

If you notice above September was originally the seventh month, October the eighth, November the ninth, and December
the tenth month. As a rule always remember that December is the 10th month when calculating the 1st month of the year.
