Midnight sun and polar night: dates in Tromsø and Reykjavik

North of the polar circle there are whole days with no sunrise or no sunset, and the exact dates depend on latitude. The tool calculates each day and says, instead of inventing a time, when the Sun simply does not cross the horizon.

When the Sun does not cross the horizon

The Arctic Circle sits at 66.56 degrees north latitude, the complement of the Earth's axial tilt. There, at the June solstice, the Sun stays above the horizon for 24 hours. Farther south the length only approaches that: Reykjavik, at 64.1 degrees, is outside the circle and on June 21, 2026 still gets 21h09 of daylight, with sunrise at 02:55 and sunset at 00:04 the next day. The Sun gets only 2.4 degrees below the horizon at its lowest and never truly gets dark. At the December solstice the same place has 4h07 of daylight, from 11:22 to 15:29.
Tromsø, in Norway, at 69.65 degrees north, shows the whole phenomenon. In 2026 the last sunset of spring is at 00:27 on May 18 and the first of summer only at 00:36 on July 26; between them the Sun does not set. May 18 and July 25 are transition days: the Sun rises, or sets, but does not do both. On June 21 its altitude goes from 3.1 degrees at midnight to 43.8 at noon. In winter, from November 28, 2026 to January 14, 2027, the Sun does not rise, and at noon on December 21 it sits 3.1 degrees below the horizon, never showing.
The end of polar night is gradual. On January 15, 2026 the Sun rises at 11:29 and sets at 12:19 in Tromsø, a day of only 50 minutes, and the day grows from there. For a traveler, the sky does not go black on those days: civil, nautical and astronomical twilight happen around midday, and bands of blue and golden light exist even without a sunrise. The tool shows those bands in the day table, tagging times from another day with +1 or -1 when the event crosses midnight.

Full tool FAQ

How do I find out when the sun rises and sets in my city?

Pick the city and date above. The time comes from the Sun's position calculated for the city's coordinates, in the city's time zone, with daylight saving time where it applies. In São Paulo on December 21, 2026 the Sun rises at 05:17 and sets at 18:52; on June 21, 2026, at 06:48 and 17:29.

What is golden hour and when does it happen?

What is blue hour?

What is the difference between civil, nautical and astronomical twilight?

Why does sunset time change so much through the year?

Is the longest day also the day the Sun rises earliest?

Why do some times show +1 day?

Are there midnight sun and polar night? What does the tool show?

Why does the time differ by a minute or two from my phone app?

Does it work offline and does it handle daylight saving time?

Frequently asked questions

When is the midnight sun in Tromsø?

In 2026 the Sun does not set from May 18 (after the 00:27 sunset) until July 26 (the 00:36 sunset). May 18 and July 25 are transition days, with only one of the two events.

What does the tool show when the Sun does not rise?

A polar night notice, a day length of zero, the Sun's altitude at solar noon and whichever twilights exist. No sunrise time is invented.

Is there midnight sun in the southern hemisphere?

Yes, inside the Antarctic Circle around the December solstice, with mirrored dates. Just type a city or station south of 66.56 degrees; the tool uses the same sunrise and sunset rule.
