The Chinese used to keep time using 2 different lists of characters, known in English as the 10Heavenly Stems and the 12Earthly Branches. The stems were the 10 days of the week under the Shang dynasty, each with its own sun and a special gift to different dead family members of the king. The branches were parts of the almost 12-year path that Jupiter takes around the sun. Each is said to be yin (dark or female) or yang (bright or male), so that when they are put together they make a list of 60 pairs. (The current list began in 1984 and will end in 2043.) Later, each of the stems was also said to match one of the 5 Chinese elements—wood, fire, dirt, metal, or water—and each of the branches was said to be a different animal: Rat, Ox & Cow, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster & Chicken, Dog, and Pig. The Han Chinese list begins with the Year of the "Wood Rat"; the Tibetan list is much the same but begins with the Year of the "Fire Rabbit".
