The Farmer’s Almanac said: “The autumnal equinox marks the turning point when darkness begins to win out over daylight.
“Essentially, our hours of daylight – the period of time each day between sunrise and sunset – have been growing slightly shorter each day since the summer solstice in June, which is the longest day of the year – at least in terms of daylight.
“Then, for the next three months, our hours of daylight continue to grow shorter.
“At the autumnal equinox, day and night are approximately equal in length.
“The name ‘equinox’ comes from the Latin word aequus, meaning equal, and nox, meaning night.”
