The dates of these events are based on the Earth’s position in relation to the Sun and can change from year to year.
This is consistent with the astronomical approach, which suggests that the equinoxes mark the transition from winter to spring and from summer to autumn. In the Southern Hemisphere, spring starts on September 23, 2023, at 06:50 GMT (2:50 a.m. Spring in the Northern Hemisphere begins on March 20, 2023, at 21:25 GMT (4:25 p.m. Here are the spring equinox dates for five years: Note that the dates above are given in the Greenwich Mean Time (GMT), and the equinox date may vary in different time zones. Meanwhile, the next equinox on September 24 will take place only in 2303. In the 21st century, the most common equinox date is September 22 - it occurs on this day 76 times. In the Southern Hemisphere, the dates of the vernal equinox vary between September 21 and 24. The other 20 equinoxes this century occur on March 19. In this century, 78 equinoxes fall on March 20, and only two occur on March 21. In the Northern Hemisphere, the spring equinox dates vary between March 19 and 21.

To avoid confusion between the different hemispheres, astronomers use the terms "March equinox" and "September equinox". That's why there the March equinox symbolizes the beginning of autumn and therefore is called the “autumnal” equinox. In the Southern Hemisphere, however, the seasons are reversed. If you live in the Northern Hemisphere, you probably use the terms "March equinox" and "vernal equinox" interchangeably because, in this region, the March equinox marks the beginning of spring and all the seasonal changes that come with it. What is March equinox & September equinox? If there were no inclination between them, there would be no seasons and solstices, and we would have the equinox all year round.Īs we mentioned, the spring equinox takes place in March or September. They are inclined to each other at 23.5°. The ecliptic is the Sun’s path across the sky the celestial equator is an imaginary line extending from the Earth’s equator into the celestial sphere. After the spring equinox, the relevant hemisphere (northern one in March and southern one in September) tilts closer to the Sun, resulting in more hours of daylight, with earlier sunrises and later sunsets.Īt the moment of the equinox, the ecliptic and the celestial equator intersect. As a result, the Sun is located directly above the equator, and both hemispheres receive an almost equal amount of sunlight. What is the spring equinox?Īs mentioned above, equinoxes occur when the Earth’s hemispheres aren’t tilted towards or away from the Sun. Spring equinox also signals the return of sunshine, warmer temperatures, blooming flowers, and other seasonal effects that are noticeable to everyone. So the beginning of a new season is celebrated worldwide with various spring traditions, holidays, and festivals.
In astronomy, the vernal equinox marks the first day of spring (as the name suggests).
