If we all knew that March 21st is the vernal equinox, since day and night are equal, the astronomical spring in the northern hemisphere actually started yesterday, March 20th. As is well known, spring in the Northern Hemisphere is also known as the March equinox, while the autumnal equinox occurs in the Southern Hemisphere.
The equinox of Mars marks the moment when the Sun crosses the celestial equator. Practically, it means that at that moment the Sun, from the southern celestial hemisphere passes to the northern celestial hemisphere. This phenomenon occurs every year on March 19, 20 or 21. The arrival of spring is determined by following the center of the Sun according to the ecliptic.
The date of the equinoxes and the solstice is not fixed due to the elliptical orbit of the Earth sun. The Earth's axis always tilts at an angle of about 23.5 ° with respect to the ecliptic - the imaginary line created by the Earth's orbit around the Sun. On any other day of the year or in the Northern or Southern Hemisphere the Earth's axis is tilted slightly toward the Sun, but at both equinoxes, the Earth's axis is perpendicular to the Sun's rays. The equinox occurs simultaneously worldwide.
At the appointed time the center of the Sun will be exactly at the intersection of the ecliptic and the celestial equator. This practically means that at that moment the Sun, from the Southern Celestial Hemisphere passes to the Celestial Northern Hemisphere.
On March 20, the day lasts 12 hours and seven minutes. Usually, the first day of spring is named as equal day, which means that the length of day and night is the same, from the moment of sunrise to the moment of sunset, 12 hours have passed.
But how is it celebrated?
The equinox and the spring solstice are celebrated in different ways in different places. Many cultures during this day (March 20 - 21) celebrate the arrival of spring with various festivals and outdoor events.
Also, Easter, the Christian holiday is associated with the movements of the Sun, so it is celebrated on different dates.
