On Earth, there are two equinoxes every year: one around March 21 and another around September 22. Sometimes, the equinoxes are nicknamed the “vernal equinox” (spring equinox) and the “autumnal equinox” (fall equinox), although these have different dates in the Northern and Southern Hemispheres.
Do equinoxes and solstices fall on the same dates each year?
Most years, this happens on either Sept. 22 or 23. However, every once in a while, the autumn equinox can occur on Sept. “Because of leap years, the dates of the equinoxes and solstices can shift by a day or two over time, causing the start dates of the seasons to shift, too,” according to The Old Farmer’s Almanac.
What is Summer Solstice and winter solstice Class 6?
The day that the Earth’s North Pole is tilted closest to the sun is called the summer solstice. It is also the day that the Sun reaches its highest point in the sky. The winter solstice, or the shortest day of the year, happens when the Earth’s North Pole is tilted farthest from the Sun.
How are equinoxes different from solstices?

Why is the first day of spring called the vernal equinox?
In the Northern Hemisphere, the March equinox is called the vernal equinox, because it signals the beginning of spring (vernal means fresh or new like the spring). When the Northern Hemisphere starts to tilt toward the sun in spring, the Southern Hemisphere starts to tilt away from the sun, signaling the start of fall.
When are the solstices and equinoxes each year?
There are two equinoxes and two solstices each year. Equinoxes occur on approximately March 21 and Sept. 22, and are referred to as the vernal and autumnal equinox, respectively. Solstices occur on approximately June 21 and Dec. 21, referred to as the summer and winter solstice, respectively.
Why do the dates of solstices and equinoxes vary?
These seasons are reversed but begin on the same dates in the Southern Hemisphere. Because Earth actually travels around the sun in 365.24 days , an extra day is needed every fourth year, creating what we know as Leap Year. This also causes the exact date of the solstices and equinoxes to vary.

(In the Southern Hemisphere the seasons are reversed.) The equinoxes happen in March (about March 21) and September (about September 23).
