Daylight savings

As of 2007, Daylight Saving Time begins in the United States on the second Sunday of March and concludes on the first Sunday of November. This is due to the fact that during the warmer months, clocks are advanced so that darkness falls later.

Daylight Saving Time causes changes in the names and acronyms used to identify the current local time in each time zone.

Eastern Standard Time (EST) changes to Eastern Daylight Time (EDT), Mountain Standard Time (MST) becomes Mountain Daylight Time (MDT), and so on.

Exceptions to the US clock change rules

Arizona (except Navajo Indian Reservation), Puerto Rico, Hawaii, the US Virgin Islands, and American Samoa do not observe Daylight Saving Time.
