Ta'anit Esther/The Fast of Esther

5:10 am | Fast begins
6:16 pm | Fast ends
The  fast on erev Purim commemorates Esther's fasting when she prepared to go to King Ahashverosh without having been summoned. The Fast of Esther is the only one of the four minor fasts that is not associated with the destruction of the Temple. Like all the other minor fasts, it is a dawn to dark fast, not a 25-hour fast beginning the evening before.
