Chinese calendar combines lunar, solar and color-animal (Stem-Branch) counting systems. The lunar counting system mainly is to count the lunar month. The solar counting system is to count the year and solar month for agriculture activities. The color animal is to count the every single solar day. At the beginning color animal counts only for the day. Later, Five Element scholars applied color animals on Year and Month cycles.
There are 12 animals, which are Rat, Cow, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Chicken, Dog, Pig, in the counting system. The Chinese calendar needs to assign a unique animal name for each day inside the lunar month. sometimes, Chinese Lunar Calendar needs to add an extra lunar month (Leap Lunar Month) in the cycle to match the speed of the solar cycle. For example, Year 2006, Chinese calendar has two 7th lunar months. A lunar month contains 29 or 30 days. Therefore, Chinese calendar needs 60 different animal names to make every single day unique for the case of leap lunar month.
