Today We Will Live 12 Hours Of Day And 12 Hours Of Night
Equinoxes occur twice a year, the Spring Equinox and the Autumnal Equinox. The Equinox of March 21, which is the equinox of the arrival of spring and the solstice, takes place today. Today, countries in the Northern Hemisphere, including our country, will experience 12 hours of daylight and 12 hours of night.
Equinox (day-day equality, day-night equality) The moment when the circle of illumination passes through the poles as a result of the sun’s rays hitting perpendicular to the Equator. It is when day and night are equal. It occurs twice a year, on March 21, the Spring Equinox and September 23, the Autumnal Equinox.
WHAT IS THE MARCH 21 EQUINOX?
In the Northern and Southern Hemispheres, the sun’s rays fall at an angle of 90° to the Equator at noon. The shadow length is zero at the Equator. The sun’s rays begin to fall perpendicular to the Northern Hemisphere from this date. From this date onwards, nights become longer than days in the Southern Hemisphere.
The opposite happens in the Northern Hemisphere. This date marks the beginning of Autumn in the Southern Hemisphere and Spring in the Northern Hemisphere. The circle of illumination passes tangent to the poles. On this date, the Sun is visible at both poles.
The duration of day and night on Earth becomes equal.
This date marks the beginning of six months of night at the South Pole and six months of day at the North Pole.
