Laws of Purim
TIMES
- Purim is preceded by the Fast of Esther, which begins at dawn on the 13th of Adar and continues until nightfall. When the 13th is on Shabbat, the Fast of Esther is observed on the preceding Thursday. It is forbidden to eat and drink on this day (one may, however, wash, and wear leather shoes).
- In unwalled cities, Purim is celebrated on the 14th of Adar, from night to night.
- In cities with walls dating from the days of Joshua, Purim is celebrated on the 15th of Adar, as it was in Shushan, the capital of Persia; hence the name, Shushan Purim. Jerusalem is a walled city and most of its suburbs are also considered part of Jerusalem regarding this law.
