Daylight saving time (abbreviated DST), sometimes referred to as daylight savings time in U.S., Canadian, and Australian speech, and known as British Summer Time (BST) in the UK and just summer time in some countries, is the practice of advancing clocks during summer months so that evening daylight lasts longer, while sacrificing normal sunrise times. Typically, regions that use daylight saving time adjust clocks forward one hour close to the start of spring and adjust them backward in the autumn to standard time.
