Equinox

The date and time when the sun crosses the equator. On that day, the day time and night time are both very close to 12 hours. This happens about March 21 and September 21.

Many religious holy days are synchronised to the equinoxes, including the Jewish Passover and Christian Easter. Wiccans, other Neopagans, Native Americans and followers of many aboriginal religions worldwide celebrate the equinoxes.
