Autumnal Equinox

First Day of Fall Autumnal Equinox is on Monday, 23 September 2019.

Autumnal Equinox means days start getting colder and shorter in Northern Hemisphere until the winter solstice in December. For the southern hemisphere, it means starting of the spring when days start getting warmer.

What is Equinox

The word equinox is formed from the Latin word “aequalis” and “nox,” means equal night hence on this day we have approximately equal daytime and nighttime all over the planet. In Northern Hemisphere, the equinox in March is called the Vernal or Spring Equinox and in September equinox is called the Autumnal or Fall Equinox and it is opposite for southern hemisphere.

What is Autumnal Equinox

Autumnal Equinox marks the beginning of Autumn in Northern Hemisphere. The exact moment when the sun is directly in line with the equator and day and night are roughly equal.

There are two Equinox every year when the sun shines directly on the equator one is Spring Equinox and other is Autumn Equinox. Spring Equinox occurs around 20 March and Autumn Equinox around 23 September in the Northern Hemisphere.

The date actually varies by one or two days as Autumn Equinox ranges from September 21 to September 24. It is the time when day and night are of equal duration and after Autumn Equinox the day will start getting shorter, and the night long.

People like to go Stonehenge in the United Kingdom to view the summer solstice and Autumn Equinox celebrations. This is the third of the four ‘sky points’ in our Wheel of the Year and it is when the sun does a perfect balancing act in the heavens. The full moon nearest to the Autumn Equinox is called the Harvest Moon and farmers would harvest their crops by then, as part of the second harvest celebration.
