The Chinese year 4715 begins on January 28, 2017. According to the Chinese zodiac it will be the Year of the Rooster (雞年 - "rooster year"; pinyin: jīnián).
The Chinese calendar is lunisolar (not purely lunar). Months begin with the new moon (when it is darkest.) New Year's Day usually falls on the second new moon after the winter solstice. The year 1 on the Chinese calendar corresponds to the first reign year of the legendary Yellow Emperor (黃帝; pinyin: Huángdì), who is said to have invented the calendar during the 61st year of his reign.
The most familiar aspect of the Chinese zodiac is the cycle of twelve animals - one per year - that begins with the rat. A lesser known cycle is that of the five phases (五行; pinyin: wǔ-xíng): wood (木; pinyin: mù), fire (火; pinyin: huǒ), earth (土; pinyin: tǔ), metal (金; pinyin: jīn) and water (水; pinyin: shuǐ). The combination of phases and animals produces a 60-year cycle, so that a 60th birthday is special cause for celebration. 2017 is a year of the Fire Rooster. Persons born in a Fire Rooster year are thought to be more flamboyant and less tactful than those born in other rooster years.
Behind the phases and animals is a system of timekeeping involving the ten "heavenly stems" (天干; pinyin: tiāngān) and twelve "earthly branches" (地支; pinyin: dìzhī). The heavenly stems (甲乙丙丁戊己庚辛壬癸) correlate to the five phases (two per phase, in the order wood, wood, fire, fire, earth, earth, metal, metal, water, water). The twelve earthly branches (子丑寅卯辰巳午未申酉戌亥) correlate to the twelve zodiac animals (in order: rat, ox, tiger, rabbit, dragon, snake, horse, ram, monkey, rooster, dog, pig). This year's stem and branch are 丁 (pinyin: dīng) and 酉 (pinyin: yǒu), respectively.
Another lesser known aspect of Chinese astrology is that the years alternate between yin (陰; pinyin: yīn) and yang (陽; pinyin: yáng). Because there are an even number of zodiac animals, each animal is considered either yin or yang. The rooster is an yin animal.
To Chinese, this most important celebration of the year is known as "Spring Festival" (春節; pinyin: Chūnjié.) It is a time of family reunion. Family members gather at each other's homes for visits and shared meals, most significantly a feast (年夜飯; pinyin: niányèfàn) on New Year's Eve (除夕; pinyin: Chúxī). In Chinese societies, people may take weeks off from work to prepare for and celebrate this holiday. With about 3 billion passenger trips over the 40-day travel season, it is described as the world's largest annual human migration.
During early periods of Chinese immigration to the United States, many Chinese arrived without their families and found a sense of community through neighborhood associations instead. Today, many Chinese-American neighborhoods and associations host New Year's banquets and other events.
At Chinese New Year celebrations people commonly wear red clothes, decorate with spring festival couplets (春聯; pinyin: chūnlián) on red paper, and give gifts of "lucky money" in red envelopes (紅包; pinyin: hóngbāo). They also set off fireworks. Both the color red and loud noises were originally thought to scare off a horrible beast that was believed to leave its lair each year at this time to eat villagers. The Chinese word for "year" (年; pinyin: nián) originates from the name of this beast.
In some areas of China, it's a popular custom to give oranges because the word used to say "orange" in those areas (橘; pinyin: jú) sounds similar to another word which means "good luck" (吉; pinyin: jí). People present oranges to their friends and relatives to express their respects and good wishes for the coming year. Two additional foods whose names are associated with auspicious words are fish (魚; pinyin: yú), which is pronounced the same as "surplus" (餘), and New Year's cake (年糕; pinyin: niángāo), which is homophonous with "venerable" (年高). Chinese dumplings (餃子; pinyin: jiǎozi) also carry special symbolism because they are shaped to resemble ingots of gold or silver (the appropriate color resulting from pan frying or boiling, respectively).
Typical Chinese greetings during the "Spring Festival" include 恭喜! ("Congratulations" - as if to say 'you made it through another winter!', pinyin: Gōngxǐ!), 恭喜發財! (same as "恭喜!" but with the added wish to "Get rich!", pinyin: Gōngxǐ Fācái!), 新年好! ("Good New Year!", pinyin: Xīnnián hǎo!); 新年快樂! ("Happy New Year!", pinyin: Xīnnián kuàilè!) and 春節快樂! ("Happy Spring Festival!", pinyin: Chūnjié kuàilè!).
The festivities of Chinese New Year traditionally end with the Lantern Festival (元宵節; pinyin: Yuánxiāojié) on the fifteenth day (first full moon) of the new year. On this day, people eat yuanxiao (元宵, sweetened dumplings made with glutinous rice flour), hang glowing lanterns in temples, and carry lanterns to evening parades under the light of the full moon. Some lanterns are true works of art, depicting birds, animals, flowers, zodiac signs, and scenes from legend and history. The Lantern Festival celebrations often culminate with a dragon dance and fireworks.
Anyone born during one of the following Chinese calendar years will have been born under the sign of the rooster: Jan 22, 1909 - Feb 9, 1910; Feb 8, 1921 - Jan 27, 1922; Jan 26, 1933 - Feb 13, 1934; Feb 13, 1945 - Feb 1, 1946; Jan 31, 1957 - Feb 17, 1958; Feb 17, 1969 - Feb 5, 1970; Feb 5, 1981 - Jan 24, 1982; Jan 23, 1993 - Feb 9, 1994; Feb 9, 2005 - Jan 28, 2006 and Jan 28, 2017 - Feb 15, 2018. Considered to share rooster traits, these individuals are thought to be flamboyant, outspoken, confident, proud and strong-willed. Other Rooster characteristics include courage, honesty, loyalty, reliability and resilience.
Persons born in Rooster years are reckoned to be compatible with persons born under the signs of the Ox or Snake, and incompatible with persons born in a Rabbit year.
Famous persons born in Rooster years include Eric Clapton, Dolly Parton and Katharine Hepburn.
