The Jewish holiday that commemorates the deliverance described in the Book of Esther is Purim.
Purim is celebrated on 14 Adar in most locations and on 15 Adar in walled cities traditionally associated with the time of Joshua, most famously Jerusalem. Its central public ritual is the reading of the Megillah, the Hebrew name for the Scroll of Esther. Listeners traditionally make noise when Haman’s name is read.
The holiday also includes gifts of food to friends, donations to people in need, and a festive meal. Costumes and dramatic performances are widespread customs, especially among children. Purim is distinct from Hanukkah: Purim recalls a threatened Jewish community in the Persian Empire, while Hanukkah commemorates the rededication of the Jerusalem Temple after the Maccabean revolt. The Book of Esther does not mention God explicitly, a feature often noted in discussions of its literary style.
