Sunrise and sunset in Oslo in October

On October 1 in Oslo the sun rises at 07:28 and sets at 18:43; on day 31 it rises at 07:43 and sets at 16:18. Over the month the day gets 161 minutes shorter.

In Oslo (59.9° latitude), October 2026 has 31 days whose sun rises at 07:28 and sets at 18:43 on the 1st, and at 07:43 and 16:18 on the 31th. Mid-month the day lasts 9 h 58 min and the sun reaches 20° above the horizon. Even so, the UV index never reaches 3 at any point in the month: at this latitude and time of year, the ozone layer absorbs UVB before enough of it reaches the ground. So in October there is no vitamin D synthesis in Oslo at any hour of the day, however long you stay out.
