Reading your clock…
Reykjavik never changes its clocks
Reykjavik stays on UTC+00:00 all year round. This is worth being careful about rather than relaxed about: the gap between Reykjavik and a city that does observe daylight saving still moves twice a year, because the other end moved. A recurring call can drift by an hour without anything changing here at all.
Time difference from Reykjavik
Where a range is shown, the gap genuinely changes during the year. That is not rounding or hedging — it is two governments moving their clocks on different weekends.
| City | Difference now | Across the year |
|---|---|---|
| London | 1 hour ahead | 0 / +1h |
| New York | 4 hours behind | −5h / −4h |
| Los Angeles | 7 hours behind | −8h / −7h |
| Chicago | 5 hours behind | −6h / −5h |
| Toronto | 4 hours behind | −5h / −4h |
| Paris | 2 hours ahead | +1h / +2h |
| Berlin | 2 hours ahead | +1h / +2h |
| Dubai | 4 hours ahead | constant |
| Mumbai | 5 hours 30 minutes ahead | constant |
| Singapore | 8 hours ahead | constant |
| Hong Kong | 8 hours ahead | constant |
| Tokyo | 9 hours ahead | constant |
| Sydney | 10 hours ahead | +10h / +11h |
| Auckland | 12 hours ahead | +12h / +13h |
| São Paulo | 3 hours behind | constant |
| UTC | the same time | constant |
Daylight in Reykjavik through the year
From about 4.1 hours in December to 21.2 hours in June. This is the part a plain clock leaves out: 17:00 is a bright evening in one month and long dark in another.
| Month | Sunrise | Sunset | Daylight |

| January | 09:15 | 15:08 | 5h 53m |
| February | 07:40 | 16:50 | 9h 10m |
| March | 06:02 | 18:16 | 12h 14m |
| April | 04:12 | 19:49 | 15h 37m |

| June | 01:27 | 22:37 | 21h 10m |
| July | 02:28 | 21:43 | 19h 15m |
| August | 04:06 | 20:00 | 15h 54m |
| September | 05:37 | 18:09 | 12h 32m |
| October | 07:05 | 16:24 | 9h 19m |
| November | 08:46 | 14:47 | 6h 1m |
| December | 09:54 | 14:02 | 4h 8m |
Daylight length is accurate. The clock times of sunrise and sunset assume each city sits at the centre of its time zone, which can put them up to about an hour and a quarter out for places near a zone's edge — Madrid being the standard example. Day length is unaffected.
Questions
About time in Reykjavik
What time zone is Reykjavik in?
Reykjavik uses the IANA time zone Atlantic/Reykjavik, a fixed UTC+00:00 with no daylight saving.
Does Reykjavik observe daylight saving time?
No. Reykjavik stays on UTC+00:00 all year. That does not mean the gap between Reykjavik and other cities is fixed, though: when a city that does observe daylight saving changes its clocks, the difference between you and them moves even though nothing changed here.
Why does the time difference to Reykjavik keep changing?
Because the two places do not change their clocks on the same weekend, and in opposite hemispheres they change in opposite directions. London is a clear example: it sits the same time, then 1 hour ahead across the year rather than one fixed distance.
How much daylight does Reykjavik get?
Around 21.2 hours at the longest, in June, and about 4.1 hours at the shortest, in December. The table on this page lists sunrise and sunset through the year. Times are calculated from Reykjavik's latitude of 64.15° and are approximate to within about an hour for cities that sit well away from the centre of their time zone.
