In 2014, Chinese New Year falls on 31 January. The lunisolar Chinese calendar(旧暦)determines the date of Chinese New Year. The calendar is also used in countries that have adopted or have been influenced by many eastern Asian countries such as Korea, Japan and Vietnam. In the Gregorian calendar, Chinese New Year falls on different dates each year, a date between January 21 and February 20. In the Chinese calendar, winter solstice(冬至)must occur in the 11th month, which means that Chinese New Year usually falls on the second new moon after the winter solstice (rarely the third if an intercalary month(閏月)intervenes). In traditional Chinese Culture, lichun(立春)is a solar term marking the start of spring, which occurs about February 4.
