Question

define equinox and its importance

Answer 1

An equinox is commonly regarded as the moment in which the plane of Earth,'s equator passes through the center of the sun's disk,which occurs twice each year, around 20 March and 23 September. This simplified, but incorrect, understanding of Earth's orbital motion can lead to errors of up to 69 seconds from the actual time of equinox.
