What does DST stand for? DST is an abbreviation for daylight-saving time, 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. 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 DST.
