More About Daylight Saving Time
What is daylight-saving time?
Daylight-saving time is the period during which the time is adjusted in order to gain an extra hour of daylight in the evening during part of the year.
Daylight-saving time begins in the spring, when clocks are set one hour ahead. They are then set one hour back in the fall. Daylight-saving time is also commonly called daylight-savings time. It’s abbreviated DST.
The term daylight saving (or daylight savings) refers to the practice of adjusting the time in this way. Both of these terms can be used as short forms of daylight-saving time. All of these terms can also refer to the specific mode of time that’s being used during a particular period, as opposed to standard time.
People often use the simple mnemonic spring forward, fall back to remember to set clocks forward one hour (e.g., from 2 a.m. to 3 a.m.) in the spring and backward one hour (e.g., from 2 a.m. to 1 a.m.) in the fall. This is often seen as resulting in one less hour of sleep time on the day that the clocks are adjusted in the spring and one more hour when they’re changed in the fall.
Daylight-saving time is widespread, but it is not observed everywhere or in the same way in all locations. In the U.S., for example, daylight-saving time is not observed by the states of Arizona or Hawaii.
Example: Don’t forget to set your clocks ahead for daylight-saving time.

More information and context on daylight-saving time
The first records of the term daylight-saving time come from the early 1900s. The practice is thought to have been first proposed by U.S. statesman and scientist Benjamin Franklin in the 1700s. The idea gained traction in the late 1800s and was first officially adopted by Germany in 1916, followed soon after by several other countries, including the U.S. in 1918. Daylight-saving time was enacted during this time in part as a way to save energy costs during World War I, and the same thing was done during World War II. An annual period of daylight-saving time was permanently enacted for much of the U.S. in 1973.
Today, the need for daylight-saving time is debated, with critics noting that it no longer serves the practical purposes that it was once intended to.
