Daylight Saving Time will be celebrating its 101st birthday this year as it was first enacted by the federal government on March 19, 1918, during World War I, as a way to conserve coal. Although it was halted nationally later that year, it has persisted in some form at local and state levels for decades before being recognized nationally in 1966 by the Uniform Time Act.
Hawaii and most of Arizona don’t take part in Daylight Saving Time. .Other non-observers are American Samoa, Guam, Puerto Rico, the Virgin Islands and the Northern Marianas Islands. Indiana introduced Daylight Savings Time in 2006.
Daylight Saving Time now accounts for about 65 percent of the year. DST will officially end at 2 a.m. on Sunday, November 3.
