What Time Do I Change My Clocks for Daylight Saving Time?

Officially, the law requires businesses and timekeeping institutions to change clocks at 2:00 a.m. when Daylight Saving Time (DST) changes occur. But you can change your clocks at a more convenient time (i.e. at bedtime the night before, or when you wake the following morning.) Just remember that when you wake up, businesses and schools will have changed their clocks and you will need to adjust your schedule accordingly.

Although most places in the United States observe daylight saving time, Hawaii and most of Arizona do not. The most recent state to begin using daylight saving time changes is Indiana (Indiana began using DST in 2006.)

When Daylight Saving Time Begins: Reset your clocks one hour ahead of time on the second Sunday in March. For example, at 2:00 a.m. you reset your clocks to 3:00 a.m. (You lose an hour of sleep.)

When Daylight Saving Time Ends: On the first Sunday in November, set your clock back one hour (you gain an extra hour of sleep.) For example, at 2:00 a.m., reset your clocks to 1:00 a.m.
