Daylight Saving Time (DST) is observed in most states in the United States, with some exceptions, including Arizona (with the exception of the Navajo Nation, which does observe DST), Hawaii, and Puerto Rico. In the United States, DST begins at 2:00 a.m. on the second Sunday of March and ends at 2:00 a.m. on the first Sunday of November. During DST, the clock is set ahead by one hour so that evenings have more daylight and mornings have less.
The Federal District of Columbia, which includes the city of Washington D.C., also observes DST.
