The Fast of Esther is considered a minor fast day. This is reflected in the way it is observed–during daylight hours–as well as the permission to work and bathe. Other minor fast days include the 17th of Tammuz, which begins the three-week period of mourning for the destruction of the Temple that concludes with the ninth of Av, and the fast of Gedaliah, observed the day after Rosh Hashanah.
