The Chinese calendar is a lunisolar calendar, akin to the Hebrew calendar & Hindu Calendar, incorporating elements of a lunar calendar with those of a solar calendar. In China today, the Gregorian calendar is used for most day to day activities, but the Chinese calendar is still used for marking traditional Chinese holidays such as Chinese New Year (Spring Festival), 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.
