It’s time to “spring forward,” even though it’s still winter, as Daylight Saving Time begins in most of the United States.
At 2 a.m. on Sunday, the nation’s official timekeeper, the U.S. Naval Observatory, will set clocks forward to 3 a.m.
Of course, the actual time measured by the observatory’s master clocks, a collection of cesium atomic clocks and hydrogen maser clocks in Washington with backups in Colorado, won’t change.
All of the country observes Daylight Saving Time except Hawaii, Arizona and number of territories near the equator, including Puerto Rico, America Samoa, Guam and the U.S. Virgin Islands.
If you’re confused about what time it is, the current time across the country’s six time zones is available online from the observatory.
The next major event in timekeeping is on June 30, when a “leap second” will be added to compensate for the earth’s gradually slowing rotation. Only computers should notice this change.
