Daylight Saving Time in the United States

In the United States Daylight Saving Time begins at 2:00 a.m. local time on the second Sunday in March. On the first Sunday in November areas on Daylight Saving Time return to Standard Time at 2:00 a.m. When Daylight Saving Time begins in the United States turn your clocks ahead one hour. At the end of Daylight Saving Time turn your clocks back one hour.

NEWS: On March 10, 2021 a bipartisan bill, the Sunshine Protection Act, was reintroduced in the US Senate that would keep the United States on daylight saving time year round. If approved when daylight saving time ends on November 7, 2021 residents in the United States would not turn their clocks back one hour to observe standard time. States and locations that do not currently observe daylight saving time, American Samoa, most of Arizona, Guam, Hawaii, Northern Mariana Islands, Puerto Rico and the Virgin Islands would not be required to make any changes.

Many states have previously introduced and passed similar legislation; however, any such change in daylight saving time observance requires approval of the federal government. Many states have seen growing support to end the practice of changing clocks twice a year to observe daylight saving time. A summary of the Sunshine Protection Act is available to read on the Senate website.

The names in each time zone change along with Daylight Saving Time. Eastern Standard Time (EST) becomes Eastern Daylight Time (EDT), and so forth. Arizona, Puerto Rico, Hawaii, U.S. Virgin Islands and American Samoa do not observe Daylight Saving Time.

In the United States, Under the Uniform Time Act, the Department of Transportation is in charge of time zones in the United States and ensuring that jurisdictions observing Daylight Saving Time begin and end on the same date.

On Monday August 8, 2005 President Bush signed into law a broad energy bill that extended Daylight Saving Time by four weeks beginning in 2007. As a result of the provisions in the bill Daylight Saving Time now begins three weeks earlier on the second Sunday in March and ends on the first Sunday in November. The United States had previously observed Daylight Saving Time from the first Sunday in April through the last Sunday in October.
