In September or October the full moon "closest to autumnal equinox" is referred to as Harvest Moon. (And the next full moon is referred to as the Hunter's Moon). The Harvest Moon was first referenced in 1706. Many tales and stories have been told centering on this time of the year - when the full moon is most beautiful. This is the time when the moon is completely illuminated as seen from the earth. It occurs when the moon is in direct opposition with the sun - on opposite side of the earth from the sun. This is a signal that "it's time to harvest the fields".Subscribe to Read!
