Concept in Definition ABC

Equinox is the denomination who receives a popular astronomical event that takes place at that time of the year in which the sun is over the Equator and is characterized by nights and days are identical all over the planet, without exceptions, this is from March 20 to 21 and from September 22 to 23 of each year.

It is worth noting that at the time when the equinox occurs, opposite seasonal changes also occur, for example, in the northern hemisphere from March 20 to 21, the spring and in the southern hemisphere the fall, while from September 22 to 23, spring begins in the southern hemisphere and autumn begins in the north.

It is precisely called that way because the word that designates it comes from the Latin aequinoctium, which refers to the same night, which, as we made explicit, is already the distinctive sign of this event.

At the equinox then, the sun achieves what it is call on astronomyzenith, which implies reaching the highest point in the sky and if we look at it from our point on earth we will verify that it is located

just above our head at a 90 ° angle. This particular location is what generates that the light emanating from the sun is projected in the same way in both hemispheres, north and south.

Meanwhile, in what corresponds to the sunrise during the exactly moment of the equinox, it will come out in the East and will be in its counterpart, the West, in all the places of our planet without there being variations as we have already indicated.
These movements only occur on the equinox because on any other day in the Northern Hemisphere the sun falls to the south and moves as do the needles of our clock, while in the southern hemisphere this is specified in the north and with a sense opposite to the sense of our clocks.
