On March 20, Pakistan and much of the world will experience the Spring Equinox, when the Sun crosses directly over the Equator.
This rare astronomical event results in almost 12 hours of daylight and 12 hours of night, signaling the start of spring in the northern hemisphere and autumn in the southern hemisphere.
Equinoxes are astronomical phenomena that occur twice a year. First in March and then in September, the Sun’s rays strike the Equator directly. As a result, day and night are nearly equal everywhere (though there are some regional exceptions).
The Spring Equinox usually occurs on March 19, 20, or 21, while the Autumn Equinox happens sometime between September 21 and 24 each year.
According to Pakistani time, the Spring Equinox (known as I‘tidal-e-Rabee‘i) will begin at 7:46 PM on March 20.
This is the moment when the Sun crosses directly over the Equator while moving northward, resulting in approximately 12 hours of day and 12 hours of night in Pakistan and most other parts of the world.
It should be noted that fhe Equator is an imaginary line drawn at the midpoint of the Earth, dividing it into equal northern and southern hemispheres.
During the Spring Equinox, since the Sun is directly above the Equator, sunlight reaches almost every part of the world in equal amounts.
On this day, the Sun rises exactly in the east and sets exactly in the west, making it an important astronomical event.
A similar event occurs in September, known as the Autumn Equinox (September Equinox), when the Sun moves from the northern to the southern hemisphere, again crossing the Equator.
