Daylight Saving Time begins for most of the United States at 2 a.m. on the first Sunday of April, which is April 7 in 2002. Time reverts to standard time at 2 a.m. on the last Sunday of October, October 27 in 2002.

The Uniform Time Act of 1966 was signed into Public Law on April 13, 1966, by President Lyndon Johnson. It created Daylight Saving Time to begin on the last Sunday of April. The law was amended in 1986 to begin Daylight Saving Time on the first Sunday in April.

Daylight Saving Time is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, the Eastern Time Zone portion of the State of Indiana, and the state of Arizona, although the Navajo Nation does participate in Daylight Saving Time.
