Sunrise and sunset in Brussels in October

On October 1 in Brussels the sun rises at 07:47 and sets at 19:16; on day 31 it rises at 07:38 and sets at 17:15. Over the month the day gets 112 minutes shorter.

In Brussels (50.9° latitude), October 2026 has 31 days whose sun rises at 07:47 and sets at 19:16 on the 1st, and at 07:38 and 17:15 on the 31th. Mid-month the day lasts 10 h 35 min and the sun reaches 30° 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 Brussels at any hour of the day, however long you stay out.
