Why Are Day & Night Equal on 23rd September?

Introduction: 23 September has special significance. This day is full of happiness for the devotees of Dera Sacha Sauda, ​​while this day is also special for the whole world. On September 23, the time of day and night is the same which means 12 hours day and full 12 hours night. And this is the special day when Revered Supreme Father Shah Satnam Singh Ji Maharaj, performed the Holy Spiritual Coronation by appointing Revered Present Spiritual Guide Saint Dr. Gurmeet Ram Rahim Singh Ji Insan as His successor.

Scientifically, on this day the Earth is tilted 23.5 degrees from its axis, when its equator lies directly in front of the Sun, then half of the Earth receives maximum light, due to which day and night are equal. This situation occurs on 23 September and 21 March every year.

The Earth is Tilted 23.5 Degrees From its Axis:

According to the information received from Saket Singh Kaurav, Curator of Regional Science Center Bhopal., the earth is tilted 23.5 degrees from its axis. Twice a year it passes in front of the equator. Because of which the situation of equal day and night is created. The Earth encounters different things as it revolves around the Sun. On September 23, the Earth passes through a region when the Sun illuminates half of the Earth.

At the same time, on June 21, such a situation is created when most of the sunlight falls on the Earth, and it becomes the longest day. Similarly, December 22 is the longest night. In 12 months, the Earth completes its orbit around the Sun. All these incidents happen because the Earth is tilted by 23.5 degrees. The tilt of the Earth was calculated from the North Pole and the South Pole. Astronomy is centuries old, even when there was no modern science, people have been counting the moon and stars.

Autumnal Equinox or Equinox:

September 23 is also called Equinox in the language of science. Equinox is derived from Latin. Equinox is made up of the words aqui and nox. Aqui means equal and Nox means night. On this day the Sun passes just above the Earth’s equator. Therefore on this day both night and day are of 12 hours each. This day is of special importance for astronomers. September 23 is also called the Autumnal Equinox. After this day, winters start coming and the days become shorter and the nights become longer.

On the contrary, the equinox occurring on March 21 is called vernal. After this summer season starts. With the onset of the summer the days become longer and the nights shorter.

When the Sun Enters the Southern Hemisphere:

The seasons on Earth change automatically, do you know why this happens? The reason behind these events is the rotation of the Sun and the Earth in the solar system. On September 23, the Sun enters the Southern Hemisphere, due to which the Sun’s rays start falling obliquely. Due to this reason, cold starts being felt after 23rd September.

Equinox is Special in Japan:

Equinox is special in Japan compared to other countries on the Earth, because September 23 is declared a public holiday in Japan. This holiday has been declared since 1948.
