The September Equinox is a holiday dedicated to when the length of day and night are approximately equal. In 2022, this event falls on September 23rd. However, scientists note that the September equinox can occur on any day between September 21 and 24. This is because the calendar and tropical years are different. Another name for the holiday is the southern equinox, as the sun moves from north to south and crosses the equator.
