Major Chinese Festivals All Major & Minor Chinese Festivals are based on the Lunar or Moon Calendar System. The most significant days are always the 1st & 15th lunar days of any month = days of Full Moon. One of the most popular gods in many Chinese homes is the Goddess of Mercy. And offerings often coincide with the above days of Full Moon.  Compiled by Master Cecil Lee, Copyright (C), Geomancy.net, January 2000 Chinese history is over 5,000 years old.
