What Is Daylight Saving Time?

Daylight Saving Time (“DST”) is the practice of moving the clocks forward one hour from Standard Time during the summer months and changing them back again in the fall. The general idea is that this allows us all to use natural daylight better: moving the clocks forward one hour in the spring grants us more daylight during summer evenings, while moving clocks back one hour in the fall grants us more daylight during winter mornings. However, DST has many detractors—and rightfully so!
Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November. 
To remember which way to set their clocks, folks often use the expression, “spring forward, fall back.”
• Daylight Saving Time begins on Sunday, March 10, 2024, at 2:00 A.M. On Saturday night, clocks are set forward 1 hour (i.e., losing one hour) to “spring forward.” Sunrise and sunset will be about 1 hour later on March 10, 2024, than the day before. There will be more light in the evening.
• Daylight Saving Time ends on Sunday, November 3, 2024, at 2:00 A.M. On Saturday night, clocks are set back 1 hour (i.e., gaining one hour) to “fall back.” Sunrise and sunset will be about 1 hour earlier on November 3, 2024, than the day before. There will be more light in the morning.
Note: Since the time changes at 2:00 A.M., we generally change our clocks before bed on Saturday.
