Lunar Coins - The Chinese animal signs are a 12-year cycle used for dating the years. They represent a cyclical concept of time, rather than the Western linear concept of time. The Chinese Lunar Calendar is based on the cycles of the moon, and is constructed in a different fashion than the Western solar calendar. In the Chinese calendar, the beginning of the year falls somewhere between late January and early February. The Chinese have adopted the Western calendar since 1911, but the lunar calendar is still used for festive occasions such as the Chinese New Year. Many Chinese calendars will print both the solar dates and the Chinese lunar dates.
