WASHINGTON—Time marches on, with a bit more skip this weekend.

Daylight saving time officially re-emerges at 2 a.m. local time Sunday for most of the United States, so it’s best to advance one’s clocks by 60 minutes before bed.

We’ll lose an hour’s sleep Saturday night, but gain more evening light in the months ahead, when the weather warms and people want to be outdoors.

No time change is observed in Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.
Standard time returns on Nov. 5.

The Commerce Department’s National Institute of Standards and Technology says daylight saving time covers 238 days, or about 65 percent of the year.
