Daylight saving time 2027
Eastern Time springs forward on Sunday, March 14, 2027 at 2:00 AM EST and falls back on Sunday, November 7, 2027 at 2:00 AM EDT – the latest dates the rule allows.

When does daylight saving time start in 2027?
At 2:00 AM EST on Sunday, March 14, 2027, clocks across the Eastern zone jump to 3:00 AM EDT and the offset changes from UTC−5 to UTC−4. The instant is 07:00 UTC – Sun, Mar 14, 7:00 AM UTC in your own time zone. There is no 2:00–2:59 AM that night, so March 14 has 23 hours.
Central Time follows at 08:00 UTC, Mountain at 09:00 and Pacific at 10:00. For those three hours New York is four hours ahead of Los Angeles instead of three – harmless for people, but worth knowing if overnight systems on both coasts exchange data.
When does daylight saving time end in 2027?
At 2:00 AM EDT on Sunday, November 7, 2027, clocks fall back to 1:00 AM EST. The instant is 06:00 UTC – Sun, Nov 7, 6:00 AM UTC for you. The hour from 1:00 to 1:59 AM happens twice, the day lasts 25 hours, and from 06:00 to 09:00 UTC New York is only two hours ahead of Los Angeles. After that the zone stays on EST until March 12, 2028.
Both dates are the latest possible: the second Sunday in March can fall no later than the 14th and the first Sunday in November no later than the 7th. That gives 2027 a long late-winter stretch of standard time, while EDT still lasts its usual 238 days. The 2026 record shows the opposite case, with the earliest possible dates.

| Eastern Time (US & Canada) | Spring forward | Sun Mar 14, 2:00 → 3:00 AM | Mar 14 07:00 |
| UK and EU | Summer time starts | Sun Mar 28: London 1:00 → 2:00 AM, Paris 2:00 → 3:00 AM | Mar 28 01:00 |

| Chile (Santiago) | Daylight time ends | Sat Apr 3, midnight → 11:00 PM | Apr 4 03:00 |
| Chile (Santiago) | Daylight time starts | Sun Sep 5, midnight → 1:00 AM | Sep 5 04:00 |

| Sydney, Melbourne | Daylight time starts | Sun Oct 3, 2:00 → 3:00 AM | Oct 2 16:00 |
| UK and EU | Summer time ends | Sun Oct 31: London 2:00 → 1:00 AM, Paris 3:00 → 2:00 AM | Oct 31 01:00 |
| Cuba (Havana) | Daylight time ends (planned) | Sun Nov 7, 1:00 AM → midnight | Nov 7 05:00 |
| Eastern Time (US & Canada) | Fall back | Sun Nov 7, 2:00 → 1:00 AM | Nov 7 06:00 |
Chile's Aysén and Magallanes regions stay on UTC−3 all year; Brisbane and the rest of Queensland do not change. Cuba skipped its November 2026 fall-back, so Havana has no March 2027 change.
When are the 2027 mismatch weeks with Europe?
Europe changes on March 28 and October 31, so North America is out of step for two weeks in spring and one in autumn. In those weeks New York is 4 hours behind London and 5 hours behind Paris, Berlin and Rome instead of 5 and 6. The affected business days are March 15–19, March 22–26 and November 1–5.
A 10:00 AM ET meeting therefore reaches London at 2:00 PM instead of 3:00 PM and Paris at 3:00 PM instead of 4:00 PM. Sydney adds its own shifts on April 4 and October 3, and Santiago's gap to New York runs from 2 hours in January to zero in the southern winter. The EST to GMT and EST to CET pages have full hour-by-hour tables for both cases.
| Period (2027) | London | Paris · Berlin | Sydney | Santiago |
|---|---|---|---|---|
| Jan 1 – Mar 13 | 5 h | 6 h | 16 h | 2 h |
| Mar 14 – Mar 27 | 4 h | 5 h | 15 h | 1 h |
| Mar 28 – Apr 3 | 5 h | 6 h | 15 h | 1 h |
| Apr 4 – Sep 4 | 5 h | 6 h | 14 h | 0 h |
| Sep 5 – Oct 2 | 5 h | 6 h | 14 h | 1 h |
| Oct 3 – Oct 30 | 5 h | 6 h | 15 h | 1 h |
| Oct 31 – Nov 6 | 4 h | 5 h | 15 h | 1 h |
| Nov 7 – Dec 31 | 5 h | 6 h | 16 h | 2 h |
How should businesses and IT teams prepare for the 2027 changes?
- Audit anything scheduled between 1:00 and 3:00 AM local time. On March 14 a job set for 2:30 AM has no matching time; on November 7 a 1:30 AM job has two. Cronie, a common Linux cron daemon, runs skipped jobs right after the jump and avoids repeating them in autumn, but other schedulers, appliances and hand-written loops may skip or double-run. The safe fix is to schedule in UTC or outside that window.
- Log and store timestamps in UTC or with an explicit offset.
2027-11-07T01:30-04:00and2027-11-07T01:30-05:00are an hour apart; "1:30 AM ET" is not enough. - Update time zone data before March. The IANA database had six releases in 2026 (2026a–2026f) as British Columbia, Alberta, the Northwest Territories, Manitoba, Morocco and Cuba changed their rules. Servers, phones, language runtimes and embedded devices still on older data will show wrong times for those places.
- Decide which zone owns each recurring meeting. A series anchored to New York moves an hour earlier for Europe on March 15–26 and November 1–5; one anchored to London moves an hour later for New York. Tell attendees before the weeks begin.
- Check payroll and rosters for overnight shifts. A shift spanning the night of March 13–14 is an hour shorter than scheduled; one spanning November 6–7 is an hour longer. Pay should follow hours actually worked.
- List devices that never update themselves – building access systems, older cameras and recorders, phone systems, vehicle and appliance clocks – and assign someone to fix them on Monday morning.
Could the 2027 dates still change?
In the United States only Congress can move them. The Sunshine Protection Act (H.R. 139), which would make daylight time permanent with a state opt-out, passed the House on July 14, 2026 by 308 votes to 117, but as of late 2026 it sits with the Senate Commerce Committee without a vote. The March 14, 2027 change is therefore still law; the daylight saving time guide tracks the federal and state proposals.
Two neighbors are worth re-checking before March. Quebec announced on October 28, 2026 that it will table a bill to end clock changes but has not chosen which time to keep: if it settled on standard time, Montreal would stay on EST while Toronto and New York move to EDT. And Cuba plans to fall back on November 7, 2027, an hour before the Eastern zone. The live Eastern Time clock always reflects the rule in force.
Frequently asked questions
Do Toronto and New York change at the same moment in 2027?
Yes. Both are on Eastern Time and both change at 2:00 AM local time, so the switch happens at 07:00 UTC on March 14 and 06:00 UTC on November 7 in both cities.
Will Europe and North America ever change on the same day?
Not under the current rules. The second Sunday in March (8–14) can never be the last Sunday in March (25–31), and the first Sunday in November is always exactly one week after the last Sunday in October, so every year has a spring gap of two or three weeks and an autumn gap of one week.
How far ahead of New York is Tokyo after March 14, 2027?
13 hours, because Japan has no daylight saving time and only New York moves. A 9:00 AM EDT call is 10:00 PM in Tokyo. From November 7, 2027 the gap returns to 14 hours.
Which places will not change their clocks in 2027?
Arizona (outside the Navajo Nation), Hawaii and the US territories; in Canada, Saskatchewan, Yukon and, after their 2026 decisions, British Columbia, Alberta, the Northwest Territories, Manitoba and northwestern Ontario west of 90°W. Mexico outside its border towns does not change either.
When is daylight saving time in 2028?
Sunday, March 12, 2028 (07:00 UTC) and Sunday, November 5, 2028 (06:00 UTC), both at 2:00 AM local time in Eastern Time.
