The Science of the Equinox:
Two days a year, the Northern and Southern hemispheres receive the same amount of sunlight. Not only that, each receives the same amount of light as they do dark — this is because the earth is tilted at a right angle to the sun, and the sun is directly over the equator. In Latin, the word equinox translates to “equal night.” The autumn equinox takes place on or near September 21, and its spring counterpart falls around March 21. If you’re in the Northern hemisphere, the days will begin getting shorter after the autumn equinox and the nights will grow longer — in the Southern hemisphere, the reverse is true.
The idea of a harvest festival is nothing new. In fact, people have celebrated it for millennia, all around the world. In ancient Greece, Oschophoria was a festival held in the fall to celebrate the harvesting of grapes for wine. In the 1700′s, the Bavarians came up with Oktoberfest, which actually begins in the last week of September, and it was a time of great feasting and merriment, still in existence today. China’s Mid-Autumn festival is celebrated on the night of the Harvest Moon, and is a festival of honoring family unity.
