Daylight saving time

<p>Daylight saving time (DST), also referred to as daylight savings time, daylight time (<a href="/facts/Daylight_saving_time_in_the_United_States/BPWrSIYG">United States</a> and <a href="/facts/Daylight_saving_time_in_Canada/m76SuxnJ">Canada</a>), or summer time (<a href="/facts/British_Summer_Time/aQGVonvg">United Kingdom</a>, <a href="/facts/Summer_time_in_Europe/YKCjFHn4">European Union</a>, and others), is the practice of advancing clocks to make better use of the longer daylight available during <a href="/facts/Summer/v3DY22Uq">summer</a> so that darkness falls at a later clock time. The standard implementation of DST is to set clocks forward by one hour in <a href="/facts/Spring_(season)/3UWDpVmx">spring</a> or late winter, and to set clocks back by one hour to <a href="/facts/Standard_time/3dKMYnjM">standard time</a> in the <a href="/facts/Autumn/Rk9KKsS2">autumn</a> (or <i>fall</i> in North American English, hence the <a href="/facts/Mnemonic/6HfDn0ks">mnemonic</a>: "spring forward and fall back").
