equinoxien

The term "equinoxien" is not a recognized or established word in common dictionaries or scientific terminology related to astronomy or calendars. It is possible that it is a neologism, a misspelling, or a term specific to a particular context or community that is not widely known.

In astronomy, the term "equinox" refers to the two occasions in the year when the Sun appears to cross the celestial equator. During an equinox, day and night are of approximately equal length all over the Earth. This occurs around March 20th or 21st (vernal equinox in the Northern Hemisphere, autumnal equinox in the Southern Hemisphere) and around September 22nd or 23rd (autumnal equinox in the Northern Hemisphere, vernal equinox in the Southern Hemisphere).

If "equinoxien" was intended to relate to this astronomical event, it might be a non-standard adjective derived from "equinox," perhaps meaning "relating to an equinox" or "occurring during an equinox." However, without further context or a clear definition, its meaning remains speculative. The standard English adjective is "equinoctial."

It is advisable to verify the source of the term "equinoxien" or to seek clarification on its intended meaning. If it is encountered in a specific text or conversation, understanding that surrounding information would be crucial to deciphering its purpose and definition.
