The winter season will enter Azerbaijan on December 21 at 19:03:01, marking the beginning of winter in the Northern Hemisphere and summer in the Southern Hemisphere, the Department of Astrophysics at the Faculty of Physics of Baku State University told APA.

On that day, the shortest daytime (day length of 9 hours 17 minutes 22 seconds) and the longest night (night length of 14 hours 42 minutes 38 seconds) will occur.

The duration of the winter season will be 88 days 23 hours 42 minutes 52 seconds.
