Adar
12th month of the Hebrew calendar
Adar (Hebrew: אֲדָר, ʾĂdār; from Akkadian adaru) 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.
In the Talmud, Adar is considered an especially joyous month, owing to Purim, which is situated in the middle of the month. This sentiment is expressed in the Talmudic declaration:
When the month of Adar begins, one increases rejoicing.
The Talmud also associates Adar with good luck and suggests scheduling court cases during this month.
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 ('Month of Adar').
In leap years, it is preceded by a 30-day intercalary month named Adar Aleph (Hebrew: אדר א׳, aleph being the first letter of the Hebrew alphabet), also known as "Adar Rishon" (First Adar) or "Adar I", and it is then itself called Adar Bet (Hebrew: אדר ב׳, bet being the second letter of the Hebrew alphabet), also known as "Adar Sheni" (Second Adar) or "Adar II". Occasionally instead of Adar I and Adar II, "Adar" and "Ve'Adar" are used (Ve means 'and' thus: And-Adar). Adar I and II occur during February–March on the Gregorian calendar.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Adar”, the useful work is to connect “12th month of the Hebrew calendar” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q212779. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
