Adar


Adar is the sixth month of the civil year and the twelfth month of the religious year on the Hebrew calendar, roughly corresponding to the month of March in the Gregorian calendar. It is a month of 29 days.

Names and leap years

The month's name, like all the others from the Hebrew calendar, was adopted during the Babylonian captivity. In the Babylonian calendar the name was Araḫ Addaru or Adār.
In leap years, it is preceded by a 30-day intercalary month named Adar Aleph, also known as "Adar Rishon" or "Adar I", and it is then itself called Adar Bet, also known as "Adar Sheni" or "Adar II". Occasionally instead of Adar I and Adar II, "Adar" and "Ve'Adar" are used. Adar I and II occur during February–March on the Gregorian calendar.
Sources disagree as to which of the two Adar months is the "real" Adar, and which is the added leap month.

Customs

During the Second Temple period, there was a Jewish custom to make a public proclamation on the first day of the lunar month Adar, reminding the people that they are to prepare their annual monetary offering to the Temple treasury, known as the half-Shekel.
