Daylight savings time once known as 'war time'
Daylight savings time is a seasonal practice that occurs in order to make better use of natural daylight. Each year, it begins on the second Sunday of March and ends on the first Sunday of November.
Daylight savings time was first introduced in the United States on March 19, 1918, under the Standard Time Act. However, it was initially referred to as "war time" — a nickname no longer in use today.
By adding an extra hour of sunlight to the day, this would, in turn, help the country save on energy costs during World War I, according to the U.S. Department of Defense. Yet, the law was only in effect for about a year and a half before it was repealed.

In February 1942, Congress implemented a law instating a national daylight savings time to help conserve fuel and promote national security and defense, hence the nickname "war time," reported the U.S. Department of Defense.
But, the law was once again repealed in 1945. For the next two decades, there were no set rules for daylight savings time, leading to much confusion across the country. It wasn't until 1966 that this changed.
When did daylight savings time start?
Congress officially passed the Uniform Time Act in 1966. This law implemented a uniform time and date for states to observe daylight savings time.
Only two states, Arizona and Hawaii, choose not to observe daylight savings time. Instead, both states stay on standard time year round.
Likewise, U.S. territories Puerto Rico, American Samoa, Guam, the Northern Marianas, and the U.S. Virgin Islands do not observe daylight savings time.
