Chinese New Year, known in modern Chinese as the “Spring Festival” (simplified Chinese 春节; traditional Chinese 春節; Pinyin: Chūn Jié), is an important Chinese festival celebrated at the turn of the traditional lunisolar Chinese calendar. Celebrations traditionally run from the evening preceding the first day, to the Lantern Festival on the 15th day of the first calendar month. The first day of the New Year falls on the new moon between 21 January and 20 February. In 2017, the first day of the Chinese New Year is on Saturday, 28 January, initiating another year of the rooster. The New Year festival is centuries old and gains significance because of several myths and traditions. Traditionally, the festival was a time to honor deities as well as ancestors. Chinese New Year is celebrated in countries and territories with significant Chinese populations, including Mainland China, Hong Kong, Macau, Taiwan, Singapore, Thailand, Cambodia, Indonesia, Malaysia, Viet Nam, Mauritius, and the Philippines. Chinese New Year is considered a major holiday for the Chinese and has had influence on the lunar new year celebrations of its geographic neighbours. Within China, regional customs and traditions concerning the celebration of the Chinese New Year vary widely. Often, the evening preceding Chinese New Year’s Day is an occasion for Chinese families to gather for the annual reunion dinner. It is also traditional for every family to thoroughly cleanse the house, in order to sweep away any ill-fortune and to make way for good incoming luck. Windows and doors will be decorated with red color paper-cuts and couplets with popular themes of “good fortune” or “happiness”, “wealth”, and “longevity”. Other activities include lighting firecrackers and giving money in red paper envelopes. Although the Chinese calendar traditionally does not use continuously numbered years, outside China its years are sometimes numbered from the purported reign of the mythical Yellow Emperor in the 3rd millennium BCE. But at least three different years numbered 1 are now used by various scholars, making the year beginning CE 2015 the “Chinese year” 4713, 4712, or 4652. The lunisolar Chinese calendar determines the date of Chinese New Year. The calendar is also used in countries that have been influenced by, or have relations with, China – such as Korea, Japan and Vietnam. In the Gregorian calendar, Chinese Lunar New Year begins at the new moon that falls between 21 January and 20 February. In the Chinese calendar, winter solstice 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 intervenes). In traditional Chinese Culture, lichun is a solar term marking the start of spring, which occurs about 4 or 5 February, which is the median date of Chinese New Year’s Day. To determine whether a year has an intercalary month, one only needs to check whether Chinese New Year is within the month of January. The Gregorian Calendar dates for Chinese New Year from 1912 to 2101 are below, along with the year’s presiding animal zodiac and its Stem-branch. The traditional Chinese calendar follows a Metonic cycle (like the modern Jewish Calendar), and returns to the same date in Gregorian calendar roughly. The names of the Earthly Branches have no English counterparts and are not the Chinese translations of the animals. Alongside the 12-year cycle of the animal zodiac there is a 10-year cycle of heavenly stems. Each of the ten heavenly stems is associated with one of the five elements of Chinese astrology, namely: Wood, Fire, Earth, Metal, and Water. The elements are rotated every two years while a yin and yang association alternates every year. The elements are thus distinguished: Yang Wood, Yin Wood, Yang Fire, Yin Fire, etc. These produce a combined cycle that repeats every 60 years. For example, the year of the Yang Fire Rat occurred in 1936 and in 1996, 60 years apart. Many people inaccurately calculate their Chinese birth-year by converting it from their Gregorian birth-year. As the Chinese New Year starts in late January to mid-February, the previous Chinese year dates through 1 January until that day in the new Gregorian year, remaining unchanged from the previous Gregorian year. For example, the 1989 year of the Snake began on 6 February 1989. The year 1990 is generally aligned with the year of the Horse. However, the 1989 year of the Snake officially ended on 8 February 1990. This means that anyone born from 1 January to 7 February 1990 was actually born in the year of the Snake rather than the year of the Horse. Many online Chinese Sign calculators do not account for the non-alignment of the two calendars, using Gregorian-calendar years rather than official Chinese New Year dates.
