What is an equinox?
|
An equinox is a period in the orbit of a plant in which the planet's orbit and position cause the Sun to pass directly over the equator. In addition to being an astronomy event of note, the equinox also marks a shift in the seasons. On Earth, equinoxes appear around 22 September and 20 March every year, although the days can shift slightly, especially since the date is calculated using Coordinated Universal Time (UTC), which means that equinoxes in the Far East can fall a day or more later than equinoxes in Europe and the Americas, because of time differences.
