The Chinese calenar is a lunisolar calendar, incorporating elements of a lunar calendar with those of a solar calendar. This measure of time is not exclusive to China, but followed by many other Asian cultures. However, it is often referred to by the Western cultures as the Chinese calendar. In most of Asia today, the Gregorian calendar is used for day to day activities, but the Chinese calendar is still used for marking traditional East Asian holidays such as the Lunar New Year (Spring Festival), and in China the Duan Wu festival, and the Mid-Autumn Festival, and in astrology, such as choosing the most auspicious date for a wedding or the opening of a building. Because each month follows one cycle of the moon, it is also used to determine the phases of the moon.
