The sun remains below the horizon during the polar night from about 26 November to 15 January, but due to the mountains, the sun is not visible from 21 November to 21 January. The return of the sun is an occasion for celebration. However, because of the twilight, there is some daylight for a couple of hours even around midwinter, often with bluish light, allowing for normal day/night cycles during the winter. The nights shorten quickly. By 21 February, the sun is above the horizon from 7:45 am to 4:10 pm and, by 1 April, is above the horizon from 5:50 am to 7:50 pm (daylight saving time). However, if one were to include astronomical twilight as "not night", then Tromsø only has 13 hours and 32 minutes of night on the winter solstice.
