When does daylight saving time start in 2027?
On Sunday, March 14, 2027, at 2:00 a.m. Federal law sets daylight saving time from 2:00 a.m. on the second Sunday of March to 2:00 a.m. on the first Sunday of November (15 U.S.C. § 260a). You lose an hour of sleep that night. Phones and computers change on their own; wall clocks, ovens and car clocks need to be set forward by hand.
Daylight saving time dates through 2030
With the federal rule, the second Sunday of March and the first Sunday of November:
| Year | Starts (spring forward) | Ends (fall back) |
|---|---|---|
| 2027 | March 14 | November 7 |
| 2028 | March 12 | November 5 |
| 2029 | March 11 | November 4 |
| 2030 | March 10 | November 3 |

Does every state change the clock?
No. The same law lets a state that lies entirely within one time zone opt out and stay on standard time all year. Hawaii and most of Arizona don’t change their clocks, and neither do Puerto Rico, Guam and the other territories that keep standard time.
Does the time change affect my pay?
If you work an overnight shift the night clocks change, the clock shows one hour more or less than you actually work. Your employer pays for the hours you really worked, and under the Fair Labor Standards Act any hours over 40 in the week are overtime at time and a half (29 U.S.C. § 207). Add up a shift that crosses the change with the hours worked calculator.
