Anonymous bureaucrats tinker with the Ohio clock at the U.S. Capitol in 1918 when daylight savings time was first instituted. |
Wikipedia says: Daylight saving time in the United States is the practice of setting the clock forward by one hour during the warmer part of the year, so that evenings have more daylight and mornings have less. Most areas of the United States observe daylight saving time (DST), the exceptions being Arizona (except for the Navajo, who do observe daylight saving time on tribal lands), Hawaii, and the overseas territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands. The Uniform Time Act of 1966 established by Congress as the system of uniform Daylight Saving Time throughout the US.
In the U.S., daylight saving time starts on the second Sunday in March and ends on the first Sunday in November, with the time changes taking place at 2:00 a.m. local time. With a mnemonic wordplay referring to seasons, clocks "spring forward, fall back"—that is, in springtime, the clocks are moved forward from 2:00 a.m. to 3:00 a.m. and in fall they are moved back from 2:00 a.m. to 1:00 a.m. Daylight saving time lasts for a total of 34 weeks (238 days) every year, about 65% of the entire year.
The following table lists recent past and near future starting and ending dates of daylight saving time in the United States:
The Ohio clock in the U.S. Capitol ticks away, except when the government is shut down and the winders of the clock are furloughed as non-essential government employees. |
