There are only two moments each year when neither pole points toward the Sun, and the Sun lies directly above Earth’s equator. These moments are the equinoxes. The March equinox happens sometime between March 19 and 21. The September equinoxoccurs sometime between September 21 and 24. In the Northern Hemisphere, the March equinox is also known as t...
The farthest points from the equator where the Sun can appear directly overhead are referred to as the tropics. The tropics are lines of latitudethat circle the Earth above and below the equator, at about 23.4 degrees north and south. This angle is set by Earth’s axial tilt. There are two moments each year when one of Earth’s poles is tilted the mo...
Every planet in the solar system, apart from Mercury, is tilted on its axis of rotation. This means each planet has its own equinoxes and solstices. Venus and Jupiter have small axial tilts of 2.6* and 3.1 degrees, respectively. Venus orbits the Sun more quickly than Earth—in Earth time, an equinox or solstice happens on Venus every couple of month...
Vernal equinox (about March 21): day and night of equal length, marking the start of spring. Summer solstice (June 20 or 21): longest day of the year, marking the start of summer. Autumnal equinox (about September 23): day and night of equal length, marking the start of autumn.

Diagram of the Earth's seasons as seen from the south. Far left: June solstice. The equinoxes are the only times when the solar terminator (the "edge" between night and day) is perpendicular to the equator. As a result, the northern and southern hemispheres are equally illuminated.
Dec 21, 2023 · What is the difference between an equinox and a solstice? When the equinox occurs, as the equi-prefix might suggest, day and night are of equal length, and it marks the onset of spring (vernal equinox) and autumn (autumnal equinox).
The Equinox in the Northern Hemisphere occurs twice a year around 20 March (the spring equinox) and around 22 September (the autumn equinox). They occur between the summer and winter solstices...
The equinoxes are when the Sun is right over the Equator, in between the two Tropics. They occur around March 21st and September 23rd and mark the beginning of spring or autumn. We call the beginning of spring the vernal equinox, while the beginning of autumn is, conveniently, the autumnal equinox.
