What is Equinox?

What is Equinox? The sun’s rays fall perpendicular to the equator on 21 March and 21 September. Days and nights are equal everywhere. This situation is called the equinox. The day means all equality. The equinox, or equinox, is the moment when the circle of enlightenment passes through the poles as a result of the sun’s rays hitting the equator perpendicularly. It is the situation where the day and the night are equal. It is repeated twice a year. It means day and night equality – day and all equality. On March 21, night and day are equal. March 21 is also called the Spring Equinox. In short, it is called the days of day and night equality, that is, March 21st, September 23rd. Equinox is the equality of day and night. Sun angles are the pole’s moment of enlightenment when falling perpendicular to the equator. It is also the beginning of Autumn in the Southern Hemisphere and Spring in the Northern Hemisphere.

On this date, the enlightenment circle passes through the poles as the sun’s rays are perpendicular to the equator. Shadow size is zero at the equator. The sun’s rays fall perpendicular to the Northern Hemisphere on March 21st. In the Northern Hemisphere, the days start to be longer than the nights. In the Southern Hemisphere, the exact opposite is experienced.

While spring is experienced in the Northern Hemisphere, there is autumn in the Southern Hemisphere. It is also the date on which a six-month day begins at the North Pole and a six-month night begins at the South Pole.

Equinox solstice dates;

  • June 21
  • 21 June 21 December

In the Northern Hemisphere it is approximately the Spring Equinox of March 21 to the Autumn Equinox of September 23 .Approximately in the Southern Hemisphere is the 21 March Autumn Equinox – 23 September Spring Equinox .

Four important days occur, depending on the Earth’s rotation around the Sun and its axis tilt. These days are also the beginning of the seasons. The dates of March 21 and September 23 are called equinox (night-day equality) dates.

Equinox Dates

  • March 21 (equinox): Night and day are equal, spring begins in the Northern Hemisphere, where we are, and the Southern Hemisphere enters autumn.
  • June 21 (summer solstice): It is the longest day and shortest night of the year. While summer begins in the Northern Hemisphere, winter begins in the Southern Hemisphere.
  • September 23 (equinox): Night and day become equal. In the Northern Hemisphere, summer ends and autumn begins. In the Southern Hemisphere, there is a transition to spring.
  • December 21 (winter solstice): It is the longest day and shortest night of the year. While winter begins in the Northern Hemisphere, summer begins in the Southern Hemisphere.

  • The sun’s rays fall on the Equator at noon at an angle of 90 °.
  • Shade size is zero at the Equator.
  • Sun rays begin to fall perpendicular to the Southern Hemisphere as of this date.
  • As of this date, the nights in the Northern Hemisphere begin to be longer than the days. The opposite happens in the Southern Hemisphere.

  • The sun rises in the east and sets in the west.
  • At points on the same longitude the sun rises and sets simultaneously only on the equinox days (12 hours apart)
  • The Sun is visible at both poles.
  • The equinox is the beginning of autumn in the southern hemisphere and the beginning of spring in the northern hemisphere.
  • The tidal amplitude is greatest.
