What is Daylight Saving Time?

Daylight saving time (abbreviated DST) is the practice of moving the clock one hour forward during the summer months, so that evening daylight lasts an hour longer.

Typically, countries 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.

Clock shifts are usually scheduled near a weekend midnight to lessen disruption to weekday schedules.
