Spring Forward/Fall Back— Sunday, March 14

One purpose of Daylight Saving Time (called "Summer Time" in many places in the world) is to make better use of daylight. Clocks are changed during the summer months to move an hour of daylight from the morning to the evening. Most of the U.S. begins Daylight Saving Time at 2 a.m. on the second Sunday, March 14.
