Definition of Equinox

Term from the English language that is translated into Spanish as “equinoccio“. This noun specifically refers to two times of the year when day and night are the same length.

Astronomical word that refers to the moment in which the sun, being on the line of the equator, makes the day and night last the same time.


The word equinox, or equinoccio, comes from the Latin aequinoctium and is the union of two roots of the same language, namely, aequus, which means “equal” and nocte, which means “night”. Ultimately, its literal meaning would be “equal night”.

The equinox, is a word in astronomy that designates the moment when the sun, being on the line of the equator, makes the day and night last the same time. This happens in the month of March, between the 20 and 21, and September, on the days between the 22 and 23 of the month.


Equinox is the name given to a Nordic series released, in its first season, on December 20, 2020. The series, created by Tea Lindeburg, is set in Denmark and its development is almost completely rural.

There is an anime called Onyx Equinox created by Sofia Alexander and distributed by the Crunchyroll company. This series was released on November 21, 2020 and is based on different mythological aspects of Mesoamerica.

For the Greeks the equinox was the special time to worship the gods Dionysus and Apollo . Dionysus was considered the god of wine and fertility, and Apollo was known to be the god of the arts.

In Germanic cultures the equinox was the time to worship Ostara , the goddess of spring. This goddess represented renewal, inner rebirth, and fertility. It is from these beliefs that the celebration of Easter is born.

The equinox was of great importance for Mesoamerican cultures, since there are different temples, such as in Chichén Itzá el Kukulkán, in which sun worship was done and special events “occurred” on the equinox.
