As what is mentioned in the Mid-Autumn Festival story of Version one, the ancient emperors had the tradition of worshiping the moon, the day was originally on the day of Autumn Equinox, not on the Mid-Autumn day. However, the Autumn Equinox is not a fixed day and the moon may not be full moon. Therefore, the day for worshipping the moon was accepted as a convention when the moon is fullest.
