What Is Vernal Equinox – Events And Dates 

The vernal equinox, also popularly known as the spring equinox, takes place when the Sun is just above the earth’s equator, on its way from South towards the North! During this time, the Sun is just above the celestial equator, thus, during this time of the year, around the globe, the sun rises in the east and sets in the west! 

The March equinox marks the unfolding of the spring season, the season of colors and new beginnings in the Northern Hemisphere. On the contrary, it brings with itself the fall season or Autumn in the Southern Hemisphere.

After the equinox, the Northern Hemisphere experiences more daylight and hot weather, whereas the Southern Hemisphere gets to experience more night hours and colder temperatures! In 2022, the equinox falls on 20th March, 11: 33 am EDT. But, as people around the world live in varying time zones, they will experience the event on different dates ranging from 19th March to 21st March!

Do We Really Experience Equal Days And Nights? 

Although it is popularly believed by the masses that on the day of the vernal equinox, the day and night have equal time periods, it is not entirely, but partially true. The time period is nearly equal between the days and nights. But it is not exactly 12 hours of the day and 12 hours of the night! There are generally more daylight hours than nighttime, because the sun is a disk, and the day is not completely over until the sun entirely sinks down West! 

Additionally, the earth’s atmosphere refracts or bends sunlight! Being a denser medium relative to the space or vacuum, it changes the path of the sunlight. Thus, we can see sunlight several minutes after the setting of the Sun, making the days and nights unequal! 

The Controversy Around The Meteorological And The Astronomical Calendar

Meteorologists divide seasons on the basis of the temperature differences and not on the relative position of the Sun in respect to the Earth. Thus, according to meteorologists, the equinox falls on 1st March.
