 Twice a year, day and night, fall into balance, lasting 1 for nearly equal length. Known as equinoxes, Latin for equal night, they occur in March and September and along with solstices mark the changing of seasons as Earth travels around the sun.  


 
 
Astronomers 2 like to describe the equinox within the conceptual celestial 3 sphere. Here the heavens are projected around the Earth, like an enormous planetarium 4. The model is bisected by the celestial equator, a projection 5 of Earth’s own equator. The equinox occurs at the point at which the sun’s path or ecliptic crosses the celestial equator. In spring it is known as the vernal equinox, and in fall the autumnal equinox.
 
 
The other two seasonal 6 points on the sun’s path are the two solstices; in the northern hemisphere, the summer solstice marks the longest day of the year, while the winter solstice marks the shortest. The seasonal aligning 7 of the sun has been more than just a unique celestial event for humankind throughout history. Ancient sites like Stonehenge in England and Machu Picchu in Peru have well documented solar alignments 8 during the solstices.
 
 
Similarly, the equinoxes have been associated with some amazing man-made phenomena 9. In the ancient Maya city of Chichén Itzá, the great pyramid known as El Castillo is oriented along cardinal 10 axis 11. During the equinoxes, shadows cast by the railings create the illusion of a writhing 12 serpent body, descending 13 the northern steps where it joins the carved serpent’s head at the base of the stairway. The cultural significance of the fall equinox and changing of seasons continues today, especially in the northern hemisphere, where the autumnal equinox occurs around harvest season.
 
 
In fact, the full moon nearest the autumnal equinox is commonly referred to as the harvest moon. In China and other Asian countries, this time is celebrated 14 with the mid-autumnal festival; the origins are linked to the birth of the moon goddess and festival traditions revolve 15 around families with reunions and feasts and special moon cakes. In Jewish culture, thanks for the harvest is given during the week-long feast of the tabernacles or Sukkot. Families eat meals in temporary shelters outside, recalling the Israelites' days in the wilderness 16 after the Exodus 17 from Egypt.
