When Does Daylight Saving Time Start 2027?Countdown date
Scroll to release dateWhen do clocks spring forward in 2027? Sunday, March 14 at 2:00 a.m. local — the latest the "second Sunday in March" rule can land; most of the US and Canada lose an hour.
Current target date: Sunday, March 14, 2027 (DST starts (spring forward)). Calendar anchors follow public observance — your school district or country may use a different day.
Daylight saving time begins Sunday, March 14, 2027, in most US states and Canadian provinces. Clocks jump from 2:00 a.m. straight to 3:00 a.m. — the 2 a.m. hour is skipped, not repeated. March 14 is the latest date the second-Sunday-in-March rule can ever land; the EU and UK don't move until two weeks later, March 28.
DST starts (spring forward)
Sunday, March 14, 2027
March 14, 2027 is the latest the “second Sunday in March” rule can land
Under the US schedule set by the Energy Policy Act of 2005, daylight saving time begins on the second Sunday of March. In 2027 that Sunday is the 14th — as late as the rule can ever push it, since a second Sunday can never fall after the 14th of the month.
Canada mirrors the same Sunday for provinces that observe DST. Clocks move from 2:00 a.m. straight to 3:00 a.m. — the 2 a.m. hour is skipped entirely, not doubled the way November's is.
Spring forward costs an hour of sleep — that's a different risk profile than fall back
This is the change researchers usually mean when they cite spikes in car accidents, workplace injuries, and even heart-attack admissions the Monday after — losing an hour hits differently than gaining one in November. If you only remember one clock-change health warning, it's about this direction.
- 2:00 a.m. → 3:00 a.m.: the 2 a.m. hour does not occur that night.
- Most-cited effects: sleep debt, Monday-morning accident upticks.
- Contrast: November's fall-back repeats an hour instead of skipping one.
- Earliest possible date under current rule: March 8 (used in 2026).
What to do the Saturday night before
- Manual clocks (cars, ovens, coffee makers) — still need a hand forward.
- Sleep schedule — shifting bedtime 15–20 minutes earlier for a few nights softens the Monday hit.
- Early meetings/flights that Sunday — double-check any invite created before the change propagated.
- Smoke/CO detector batteries — the classic "change your clocks, change your batteries" reminder applies to both DST dates, not just fall.
The US and Europe are two full weeks apart in 2027 — not the usual one-week gap
Most years the US/Canada spring-forward Sunday and the EU/UK's last-Sunday-of-March date sit one to two weeks apart. In 2027 the gap is a full two weeks: US March 14, EU/UK March 28. For roughly a fortnight, a “what time is it there?” calculation that assumes both sides already changed will be off by an extra hour.
That window matters more for scheduling international calls and flights than for anything domestic — mark both dates if your calendar spans the Atlantic.
Frequently asked questions
Quick answers about this release date.
1What time do clocks change when DST starts in 2027?
In US and Canadian regions that observe it, local time springs forward from 2:00 a.m. to 3:00 a.m. on Sunday, March 14, 2027. That hour — 2:00 to 2:59 a.m. — does not happen at all that night.
2Is March 14 always the date?
No. The rule is the second Sunday in March, which can land anywhere from March 8 to March 14 depending on the year. 2027's March 14 is the latest possible date the second-Sunday rule allows — 2026's was March 8, the earliest possible.
3Do I gain or lose an hour in March?
You lose an hour of clock time (and typically sleep) in spring — the opposite of the November “fall back,” when the hour repeats. Studies on sleep loss, workplace accidents, and even heart-attack rates cluster around this spring change specifically, not the autumn one.
4Does Europe spring forward on the same day?
No. The EU and UK move clocks forward on the last Sunday of March — March 28, 2027, two weeks after the US/Canada date. Arizona (mostly) and Hawaii don't move at all in either direction.
