Spring forward: When does the time change? When does daylight saving time start?

If you’re tired of the dark, dreary afternoons, you only need to hang on a little while longer – the time change is just around the corner.

Daylight saving time officially starts Sunday, March 8 at 2 a.m. Since most people don’t want to get up in the middle of the night to change their clocks, it’s common practice to “spring forward” ahead one hour before going to bed Saturday night (or just let your smart devices change themselves.)

Sunrise and sunset will be about one hour later on March 8, pushing the daylight hours into the afternoon.

We will enjoy the brighter afternoons until Nov. 1 when daylight saving time ends and we “fall back” by moving our clocks back one hour.

Why do we change our clocks?

Daylight saving time originally began as an effort to save fuel used to light and heat homes during war time. It went away shortly after World War I, only to return during World War II. It was used year-round during the war but the practice wasn’t used consistently among the states after the hostilities ended.

It took federal action to standardize the time change.

Congress passed the Uniform Time Act in 1966, establishing a schedule for DST: clocks would be moved ahead one hour on the last Sunday in April and one hour back on the last Sunday in October.

The schedule was altered several times in the following decades, most recently by the Energy Policy Act of 2005, which set the start of DST (springing forward) at the second Sunday in March and the ending of DST (fall back) on the first Sunday in November.
