For a change the equinox is on Septembre 22nd this year (it will be on the 23rd next year) and obviously marks the beginning of autumn. The autumn equinox – also known as the September equinox – occurs when the earth’s equator passes the centre of the sun. This means the north and south poles aren’t tilted towards or away from the sun but are aligned in a straight line. This theoretically allows the same amount of daylight in both of the Earth’s hemispheres. On the date of the equinox, at any location, the lengths of day and night are roughly equal.
Autumn is slowly slipping into winter. This transition allows us to get used to the colder weather that will come.
