Spring Equinox: What is it and When is It?

The spring equinox is he time of year when the length of day and night equalize as a consequence of the position of the Earth’s axis with respect to the Sun, which allows the sun’s rays to fall equally on both hemispheres. As such, it is an astronomical event that marks the entrance of spring.

During the spring equinox, the Sun, in its journey through the firmament, crosses the celestial Equator. Also, during this event, we can appreciate the Sun in a perpendicular position with respect to us.

The spring equinox takes place between the days March 20 and 21 in the northern hemisphereand the days September 22 and 23 in the southern hemisphere. As such, the vernal equinox only occurs once a year in each hemisphere. Parallel to it, in the opposite hemisphere the autumn equinox.

The spring equinox also has other consequences for life on Earth. The days, for example, begin to have more and more minutes of sunlight; the sun rises earlier in the morning and sets later each day. This produces the need to change the time at the end of March to enjoy sunlight for longer. This trend continues until the Summer Solsticein which we experience the longest day of the year.

On the other hand, the spring equinox says goodbye to winter, which means that from then on the days will gradually become warmer. During this season, nature begins to turn green and reaches its fullness. Hence, spring has been associated since ancient times with rebirth. It is at this time that the Eastera festival whose elements, eggs and rabbits, symbolize fertility.
