Today is the Spring Equinox, a.k.a. the Vernal Equinox, in the Northern Hemisphere and the Autumnal Equinox, a.k.a. the Fall Equinox, in the Southern Hemisphere  That means the day time and night time are roughly the same length.

Today is the Spring Equinox in the Northern Hemisphere and the Autumnal Equinox in the Southern Hemisphere. That means the days will start getting progressively longer (or shorter), depending on which side of the Equator you reside.

An equinox usually falls on around 20 March or 22 September. Spring Equinox falls on 20 March in 2019. Autumn Equinox falls on 23 September in 2019.

On an equinox, the length of day time and night time is roughly – but not exactly – the same. The date of an equinox also varies a bit by location. While it falls on 20 March this year in the United States, it falls on 21 March in Japan.

The Spring Equinox is also known as the Vernal Equinox; the Autumnal Equinox, the Fall Equinox. The Spring Equinox marks the first day of spring; the Autumnal Equinox, the first day of fall.

The days get progressively longer after the Spring Equinox until the Summer Solstice, which marks the first day of summer. It is also the longest day of the year.

The days get progressively shorter after the Autumnal Equinox until the Winter Solstice, which marks the first day of winter.

A solstice usually falls on around 21 June and 22 December. It is also the shortest day of the year

As usual, the summer solstice falls on 21 June in 2019. The winter solstice falls on 22 December in 2019.

Many important religious or cultural feasts, festivals, and holidays are celebrated on or near these four dates in various societies around the world.
