The Esther Fast is observed on the day preceding the festival of Purim, specifically on March 2. This minor fast commemorates events from "The Book of Esther," where it is believed that Esther and the Jewish community of Shushan fasted for three days in response to Haman's plans to annihilate the Jews. The fast begins at dawn and ends at sunset, during which food and water are forbidden, although other physical comforts are allowed. The observance serves to memorialize Esther's bravery and the Jewish community's plea for divine favor before they engaged in battle against their enemies. The fast has been a tradition among Jews for centuries, reflecting both a somber remembrance and a preparation for the celebrations of Purim that follow.
