Reykjavik does not observe daylight saving time in 2026 — and its offset of UTC+00:00 never changes. This page explains why, what that means for residents and for scheduling with places that do change their clocks, and how Reykjavik compares with cities that observe daylight saving.

Why Reykjavik does not observe daylight saving

Iceland stays on UTC+0 all year — effectively permanent summer time for its longitude. The country tried daylight saving in the 20th century and dropped it; its high latitude makes the clock change less useful because summer days are already extremely long.

What never changing means

For residents, nothing changes: the clocks are never moved, the Sun rises and sets at roughly the same clock time all year (with the natural seasonal drift), and there is no lost hour of sleep in spring and no repeated hour in autumn. For scheduling, the time in Reykjavik is the easiest kind to work with — it is a fixed number, and the only thing that moves is the time in the place you are dealing with.

That does not mean the time difference never changes. The difference between Reykjavik and New York is 5 hours ahead in January and 4 hours ahead in July, because New York changes its clocks and Reykjavik does not. The difference with London is the same time in January and 1 hour behind in July. So if you schedule with a place that observes daylight saving, you still have to watch the change dates — they are the other side's dates, not Reykjavik's.

Reykjavik compared with other cities

How 2026 daylight saving compares in three major cities:

City 2026 clocks forward 2026 clocks back Standard offset Daylight offset
Reykjavik — does not observe — UTC+00:00 —
London 29 March 2026 25 October 2026 UTC+00:00 UTC+01:00
New York 8 March 2026 1 November 2026 UTC−05:00 UTC−04:00

The comparison shows the two things that matter: whether the city observes daylight saving at all, and — if it does — whether it changes on the same dates as Reykjavik. Cities that change on different dates have a shifting difference for a few weeks a year; cities that do not observe it at all have a difference that moves when Reykjavik changes. The daylight saving time 2026 dates guide lists every zone's 2026 dates in one table.

Scheduling around the change

The rule for Reykjavik is simple: your clocks never change, so your side of any meeting is fixed — but check the other side's change dates. If you meet weekly with New York, the meeting will move by an hour relative to New York on the second Sunday of March and the first Sunday of November. If you meet with London, it will move on the last Sunday of March and the last Sunday of October. Put the UTC time in the invitation and the problem goes away: a UTC event moves correctly when the other side's clocks change. The meeting planner shows the overlap for any two cities on any date.

Reykjavik and the clock changes elsewhere

The time difference between Reykjavik and another city is only constant if both cities change their clocks on the same dates — or if neither changes them at all. The table shows the difference in hours between Reykjavik and New York and London in four months of 2026. A change between two columns means one of the two cities changed its clocks in between.

Difference with January April July October
New York +5h +4h +4h +4h
London 0h -1h -1h -1h

The classic trap is the three weeks in March: the United States changes its clocks on the second Sunday of March, and Europe does not change until the last Sunday of March, so for those three weeks the New York–London difference is 4 hours instead of 5, and every standing meeting between the two shifts by an hour. Reykjavik is affected in the same way whenever its own change dates differ from the other side's. The time difference calculator works out the difference for any two cities on any date, and the meeting planner shows the overlap — use them for the weeks around the changes rather than trusting a remembered difference.

Daylight saving in Europe

In Europe, daylight saving is harmonised: almost every country changes on the last Sunday of March and the last Sunday of October, under the European Union's rules. The exceptions are Iceland, which stays on UTC+0 all year, and Russia, Belarus and Türkiye, which have abolished the change and stay on permanent time. The European Parliament voted in 2019 to end the twice-yearly change, but member states have not agreed on whether to stay permanently on summer or winter time, so the change continues for now. Reykjavik follows the European dates where they apply — and where it does not, the difference with its neighbours shifts for a few weeks a year.

Frequently asked questions

Does Reykjavik observe daylight saving in 2026?

No. Reykjavik does not observe daylight saving, so there is no clock change in 2026 and the offset stays at UTC+00:00 all year.

Why does Reykjavik not observe daylight saving?

Iceland stays on UTC+0 all year — effectively permanent summer time for its longitude. The country tried daylight saving in the 20th century and dropped it; its high latitude makes the clock change less useful because summer days are already extremely long.

What is Reykjavik's UTC offset?

Reykjavik is on UTC+00:00 in standard time, all year. Its IANA time zone is Atlantic/Reykjavik.

When does daylight saving start in Reykjavik in 2027?

Reykjavik does not observe daylight saving, so there is no clock change in 2027 either.

What time zone is Reykjavik in?

Reykjavik is in the IANA time zone Atlantic/Reykjavik, in Iceland. See the time in Reykjavik page for the full explanation.

What happens if I schedule a meeting for 02:30 on the day the clocks change in Reykjavik?

Nothing unusual happens in Reykjavik, because its clocks never change — but check the other side: if the other city observes daylight saving, its 02:30 on its change day may not exist or may happen twice.
