Words nearby equinox
What is an equinox?
An equinox is one of the two times of the year when the amount of daylight and nighttime hours are just about of equal length. The two equinoxes occur around March 20–21 and September 22–23.
The equinoxes occur on these days, but an equinox is not the whole day—it is the moment when the sun is directly above Earth’s equator. The word equinox can also refer to the position of the sun at this moment. This can also be called the equinoctial point.
The equinoxes are traditionally considered to mark the start of spring and fall. In the Northern Hemisphere, the vernal equinox (or spring equinox) occurs in March and the autumnal equinox occurs in September. In the Southern Hemisphere, it’s the reverse.
In contrast, a solstice is one of the two times of the year when the positioning and tilt of Earth relative to the sun results in the most amount of daylight time or the least amount of daylight time in a single day.
There are two solstices during the year: one that occurs around June 20–22 (usually June 20 or 21) and one that occurs around December 20–23 (usually December 21 or 22). In the Northern Hemisphere, the summer solstice occurs in June and the winter solstice occurs in December. In the Southern Hemisphere, it’s the reverse.
Example: Many ancient cultures recognized and observed the equinoxes as times that marked the change of the seasons.
Where does equinox come from?
An equinox is a moment, not an entire day. Since Earth is in motion, the exact positioning considered an equinox only happens for a moment. However, the word is most commonly used to refer to the day on which this happens. On most calendars, these days are used to mark the beginning of spring and fall similar to how the days of the two solstices are used to mark the beginning of summer and winter.
While the day of an equinox has equal amounts of daylight and darkness, the days on which the solstices occur are known for being the longest and shortest days of the year in terms of daylight. During the summer solstice, Earth is tilted toward the sun and receives sunlight for the longest time, resulting in the longest day of the year. During the winter solstice, Earth is tilted away from the sun and receives sunlight for the shortest time, resulting in the shortest day of the year. After the winter solstice, the days start getting longer (receiving more daylight time), reaching an equal amount on the day of the spring equinox. After the summer solstice, the days start getting shorter (receiving less daylight time), reaching an equal amount again on the autumnal equinox.
