The Equinox Center is for all astronomers and lovers of time and space!
An Equinox is the exact moment in time when the plane of the Earth’s equator passes through the center of the suns disk.
This happens twice per year.
Usually on the 20th of March or thereabouts and again on the 23rd of September.
Amazingly on Equinox days the duration of day and night is the same all around the world!
So be sure to mark those dates in you calendar!
