Adar (אדר, Standard HebrewAdar, Tiberian HebrewʾAḏār: from Akkadianadaru) is the sixth month of the ecclesiastical year and the twelfth month of the civil year on the Hebrew calendar. It is a winter month of 29 days. In leap years, it is preceded by a 30-day month named Adar Alef, Adar Rishon or Adar I and it is then itself called Adar Shenei or Adar II. Occasionally instead of Adar I and Adar II, "Adar" and " Veadar" are used.
