Autumn will begin at 2:04 am on the 23rd of September, when the Sun will once again cross the plane of the Earth's equator.
From this moment on, the Sun will be seen below the equator, hence, in the northern hemisphere, this event is designated as the autumnal equinox.
Despite this name, it is only three days later that the duration of the night will be the same as that of the day, because, due to atmospheric refraction, the Sun is always seen slightly above its real position, advancing each dawn and delaying each dusk.
Autumn 2022 will last until 21:48 pm on December 21st, when the winter season will begin.
The seasons of the year happen due to the tilt of the Earth and its movement around the Sun, the translation that lasts for 1 year.
The beginning of the seasons is marked by the solstices and equinoxes. Each of them takes place twice a year. There are the summer and winter solstices, as well as the spring and autumn equinoxes.
On the 30th of October, at 2:00 am, the clocks will be changed to 1:00 am, starting winter time.
