Calendar Systems
Chinese timekeeping is not a single calendar. It is six interlocking systems, each developed for a different purpose, all still in active use today.
二十四节气
Inscribed on UNESCO's Intangible Cultural Heritage list in 2016. Each term marks 15° of the sun's annual journey — a precise agricultural and cultural calendar used for over 2,000 years.
Around January 6 each year
WinterThe coldest period approaches. Traditional farmers completed final winter preparations. Families ate warming foods: lamb hotpot, glutinous rice porridge with dates and nuts.
Around January 20 each year
WinterThe peak of winter cold. In northern China, rivers froze solid. The traditional Laba Festival falls near here — families make Laba porridge (腊八粥) with eight grains to celebrate abundance.
Around February 4 each year
SpringLi Chun is the most important term for Chinese metaphysics. It marks the new solar year in traditional BaZi (八字) calculation — before the Lunar New Year. Families bit spring onions (咬春) and ate spring rolls to "bite into spring."
Around February 19 each year
SpringThe first rains after winter. In Sichuan, sons-in-law traditionally gave their mothers-in-law a bamboo-woven back basket (背篓) as thanks. Rain returns to nourish the waiting earth.
Around March 6 each year
SpringThunder wakes the hibernating animals. In some regions, people symbolically beat villainous figures (打小人) to ward off negative influences for the year. Spring thunder was both feared and welcomed.
Around March 20 each year
SpringDay and night become equal. A famous tradition: standing an egg upright on a flat surface (春分竖蛋). In theory, eggs stand more easily at the equinox — tradition says it brings good luck.
Around April 5 each year
SpringThe most important ancestor-honoring day. Families visit graves, sweep tombs (扫墓), and offer food and paper goods. Spring outings (踏青) celebrate the vibrant new growth.
Around April 20 each year
SpringRain nourishes the grain sprouts. This term gives its name to the finest first-flush tea of the year — tea picked before Grain Rain (雨前茶) is considered exceptionally tender and fragrant.
Around May 6 each year
SummerSummer officially begins. Families weighed children (称人) to check their health after spring. Eating eggs (吃蛋) was believed to strengthen the body for the heat ahead.
Around May 21 each year
SummerGrain ears fill but have not yet ripened — "small fullness." A reminder that abundance requires patience. Bitter herbs were eaten to prepare the body for summer heat.
Around June 6 each year
SummerTime to plant millet and harvest winter wheat — the busiest farming period. A farewell ceremony for flower spirits (饯花神) marked the passing of peak spring beauty.
Around June 21 each year
SummerThe longest day. Ancient emperors performed elaborate rituals facing south to acknowledge the sun's peak. Families ate noodles (冬至饺子夏至面) to celebrate and add a year of longevity.
Around July 7 each year
SummerHeat intensifies. Traditional medicine advised reducing physical exertion and eating cool foods like mung bean soup (绿豆汤). The lotus flowers in full bloom.
Around July 23 each year
SummerThe hottest days of the year. In some regions, families drank herbal teas, burned incense, and "stewed" in the heat intentionally — sweating was thought to purge winter toxins.
Around August 7 each year
AutumnA vital moment. Families weighed themselves against their spring weight (贴秋膘) — tradition said you should eat heartily to "add autumn fat" before winter. The first hint of coolness arrives.
Around August 23 each year
AutumnHeat finally retreats. This is the term happening now or very recently. The Ghost Festival (中元节) falls near here — lanterns are floated on water to guide wandering spirits.
Around September 8 each year
AutumnDew forms on leaves and grass in the morning — a visible sign of cooling. Families collected dew and mixed it with chrysanthemum wine for health. Geese begin their southward migration.
Around September 23 each year
AutumnThe second great balance point. China's national Farmers Harvest Festival (中国农民丰收节) was established on this date. Another day for standing eggs. Mooncakes and reunion.
Around October 8 each year
AutumnDew turns cold — barely above freezing. Chrysanthemum wine (菊花酒) is drunk on the Double Ninth Festival (重阳节). Elders are honored. The mountains begin to show autumn colors.
Around October 23 each year
AutumnThe first frost arrives. Red persimmons (柿子) ripen on bare branches — a symbol of good fortune. Families eat persimmons to "smooth things over" and bring good luck.
Around November 7 each year
WinterWinter officially begins. Families in northern China make dumplings (饺子) together — the folded shape resembles ancient ingots, bringing wealth. Southern families may make glutinous rice (汤圆).
Around November 22 each year
WinterLight snow may fall. Traditional families began making cured meats (腊肉) and preserved vegetables for winter. The first snowfall was considered auspicious.
Around December 7 each year
WinterHeavy snow is expected. A famous saying: 大雪兆丰年 — "heavy snow foretells a prosperous year," because snow insulates crops and kills pests. Warming foods like mutton soup are eaten.
Around December 22 each year
WinterOne of the most celebrated terms — as important as Chinese New Year in some families. Northern families eat dumplings (饺子); southern families eat tangyuan (汤圆, sweet rice balls). Ancestors are honored with offerings.
Traditional Festivals
Each festival is a cultural compression: centuries of story, belief, and communal practice packed into a single day on the lunar calendar.
The most important festival in Chinese culture. After a year of separation, families reunite for the New Year Eve dinner (年夜饭) — considered the most important meal of the year. Fireworks drive away the mythical monster Nián (年), who feared loud noise and red color. The tradition began in ancient agricultural communities as a way to mark the end of winter and celebrate survival.
The final night of New Year celebrations. Under the first full moon of the lunar year, families carried lanterns through the streets, solved riddles written on lanterns (猜灯谜), and watched dragon and lion dances. In ancient times, the relaxed social rules allowed young people to meet potential partners under the lanterns — hence its association with romance.
Originally a solar term before becoming a festival. Families visit the graves of ancestors, sweep and clean the tombs, leave food offerings, and burn paper goods for the departed. The tradition merges ancestor reverence with a celebration of spring's arrival — mourning and joy held together.
Commemorates the poet-official Qu Yuan (屈原, 340–278 BCE), who drowned himself in the Miluo River to protest government corruption. Villagers raced boats to rescue him and threw rice dumplings into the river to keep fish from eating his body. Over 2,000 years later, the race continues.
The legend of the Weaver Girl (织女, Vega) and the Cowherd (牛郎, Altair) — two stars separated by the Milky Way, allowed to meet only once a year when magpies form a bridge. Young women would display needlework skills and pray for dexterity and good marriages. The meeting of the two stars is visible in the night sky each year.
The gates of the underworld open, and wandering spirits return to the living world for a month. Families burn paper offerings — money, clothing, houses, electronics — to provide for departed relatives. Floating lanterns guide lost spirits on water. The festival blends Buddhist, Taoist, and folk traditions of ancestor reverence.
Celebrates the harvest and the full moon — the most perfectly round (and thus reunion-symbolizing) moon of the year. The legend of Chang'e (嫦娥) who drank an immortality potion and floated to the moon is told to children. Families sit outside together, eat mooncakes, and admire the moon.
The number 9 (阳数 — yang number) doubled creates maximum yang energy, which traditional belief associated with both power and the risk of bad fortune. Families climbed hills to escape the energy, drank chrysanthemum wine for health, and wore zhuyu (茱萸) herb sachets for protection. Now designated as Seniors' Day.
On the eighth day of the twelfth lunar month, families cook Laba porridge (腊八粥) — a multi-grain porridge with eight or more ingredients: rice, millet, glutinous rice, various beans, peanuts, dates, lotus seeds, and more. The tradition connects to Buddhist harvest offerings and imperial winter rituals. Some families also make Laba garlic — garlic pickled in vinegar that turns green.
The most emotionally significant night of the year. The family reunion dinner (年夜饭) must be complete — no empty seats. Every dish has symbolic meaning. Families stay up until midnight (守岁 — keeping watch over the year), setting off fireworks and lanterns to mark the transition.
Traditional Almanac — 黄历
Every Chinese calendar app shows today's "suitable" (宜) and "avoid" (忌) activities. But where do these come from — and why do different sites disagree?
The most widely used system. Each day is assigned one of twelve officers in a repeating cycle: 建 (Establish), 除 (Remove), 满 (Full), 平 (Balance), 定 (Stable), 执 (Execute), 破 (Break), 危 (Danger), 成 (Success), 收 (Receive), 开 (Open), 闭 (Close). Each officer has traditional associations for what activities are auspicious or inauspicious. The cycle is anchored to the day's Earthly Branch and the current solar term. Today's day branch is 亥Hài.
Source: Traditional Chinese almanac systemThe sky is divided into 28 lunar mansions corresponding to the moon's nightly position. Each mansion has associations with different activities. This system appears in traditional almanacs alongside the Twelve Day Officers and sometimes produces different recommendations for the same day — which is one reason why different calendar websites disagree.
Source: Ancient Chinese astronomical traditionA collection of auspicious and inauspicious "spirit-deity" designations that move through the calendar based on the year's Heavenly Stem and Earthly Branch, the month, and the day. This system adds a third layer of complexity. This year's Heavenly Stem is 丙 (Bǐng (Fire+)), which activates specific spirit configurations. Different almanac editors choose different combinations of these deities, producing different lucky/unlucky results.
Source: Traditional metaphysical systemWhy do different websites disagree? Because there is no single canonical Chinese almanac. Traditional almanac editors select different combinations of the three systems above, weighted differently, resulting in legitimately different outputs. None of these systems are scientifically validated. They are cultural and traditional frameworks developed over centuries to help communities make decisions and mark significant moments. This site presents them transparently, as exactly what they are.
