Daylight-saving time returns at 2 a.m. Sun., March 8 and will remain in effect until Sun., Nov. 1.

The extra hour of daylight in the evening provides more opportunities for leisure time activities. Others say it also saves energy.

Clocks "spring forward" in March and "fall back" in autumn.

Many people find it easier to just turn their clocks and watches forward before going to bed on Saturday night.

Some electronic devices are preprogrammed for the time change but still use the old formula. Clocks previously changed the first Sunday in April and the last Sunday in October.
