AUTUMN 2020 is really over

#HERFST2020 : The meteorological winter 2020 started December 1.
On December 21, the winter officially begins, at least according to #astronomische calendar.
For the #meteorologen and #klimatologen winter has already started on 1 December and the season lasts exactly three calendar months. The climatic seasonal classification where the seasons always start on the first of the month allows meteorologists to compare the seasons. According to the astronomical calendar, the #winter usually on December 21, but sometimes the 20th or 22nd is the start date.
On the first day of the winter season, the sun is perpendicular to the Capricorn. The differences in times and sometimes dates are due to the odd number of days of the tropical year (on which the calendar is based) and the introduction of the leap day.
