Purim is celebrated annually according to the Hebrew calendar on the 14th day of the Hebrew month of Adar (and on Adar II in Hebrew leap years that take place every 3 to 4 years), the day following the victory of the Jews over their enemies. In cities that were protected by a surrounding wall at the time of the Biblical Joshua, Purim is instead celebrated on the 15th of the month of Adar on what is known as Shushan Purim, since fighting in the walled city of Shushan continued through the 14th day of Adar. Today, only Jerusalem celebrates Purim on the 15th of Adar.
Purim begins at sundown and continues through the following day until nighfall.
