Ta’anit Esther, or the Fast of Esther, falls in the spring on the thirteenth day of the Jewish month of Adar. This public fast commemorates Esther’s bravery and communal leadership in approaching King Ahashveros. This heroic act saved the Jewish people from Haman’s plot to kill all the Jews of Shushan. If Ta’anit Esther falls on a Friday or Saturday, the fast is moved to the preceding Thursday.
