An equinox occurs twice a year, when the tilt of the Earth’s axis is inclined neither away from nor towards the Sun. The Sun is vertically above a point on the Equator.
The 2009 vernal (spring) equinox occurred in Paradelle at 7:44 AM EST (11:44 UTC).
The word equinox is derived from the Latin aequus (equal) and nox (night), because the night and day are approximately equal in length.
An equinox actually occurs at two specific moments in time, though commonly people refer to the two days as an equinox. Those moments when the Sun can be observed to be vertically above the Earth’s Equator happen around March 20/21 and September 22/23 each year.
