🌤️ Solar Terms
48 articles — The complete traditional Chinese agricultural calendar
Beginning of Spring
Among all twenty-four solar terms of the traditional Chinese calendar, none carries quite the weight of anticipation as Lichun. Occurring annually between February 3rd and 5th, this first solar term heralds the end of winter's grip and the stirring of life beneath the frozen earth.
Rain Water
Rain Water (雨水, Yǔshuǐ) arrives as the second solar term in the traditional Chinese calendar, usually falling between February 18th and 20th. Unlike the dramatic storms of summer, Rain Water brings a gentler transformation — the slow thawing of frozen earth, the first tentative drizzle of spring, and the quiet awakening of dormant seeds beneath the soil.
Awakening of Insects
There comes a moment each year, usually around March 5th or 6th, when the sky breaks open. A deep rumble rolls across the land, and with it, the earth seems to exhale.
Spring Equinox
The Spring Equinox (春分, Chūnfēn) represents one of the most poetically balanced moments in the Chinese solar calendar — the day when light and darkness stand as equals, when yang and yin achieve perfect equilibrium. Falling annually between March 20th and 22nd, Chunfen marks the fourth solar term and the true midpoint of spring.
Pure Brightness
Among all twenty-four solar terms, Qingming (清明) occupies a unique position — it is simultaneously an astronomical marker, a traditional festival, and one of China's most emotionally resonant occasions. Falling annually between April 4th and 6th, this fifth solar term arrives when spring is at its most radiant, when the landscape has been washed clean by gentle rains and the world appears fresh, bright, and full of promise.
Grain Rain
Grain Rain (谷雨, Gǔyǔ) arrives as the sixth and final solar term of spring, typically falling between April 19th and 21st. Its name carries a beautiful simplicity: 谷 (gǔ) means grain, and 雨 (yǔ) means rain — together declaring that the spring rains nourish the hundred grains.
Beginning of Summer
The Beginning of Summer (立夏, Lìxià) arrives as the seventh solar term in the Chinese calendar, typically falling between May 5th and 7th. The character 立 (lì) means "to establish" or "to begin," while 夏 (xià) means "summer" — together declaring that the season of heat and vigorous growth has officially arrived.
Grain Full
Grain Full (小满, Xiǎomǎn) occupies a unique place among the twenty-four solar terms — it is the only one whose name contains the character 小 (xiǎo), meaning "small" or "lesser. " Falling between May 20th and 22nd, Xiaoman describes a state of incompleteness that Chinese philosophy regards as the most auspicious condition of all.
Grain in Ear
Grain in Ear (芒种, Mángzhòng) arrives as the ninth solar term in the Chinese calendar, typically falling between June 5th and 7th, and it is universally recognized as the busiest agricultural period of the entire year. The name itself captures the dual urgency of the season: 芒 (máng) refers to the awns — the bristly beard-like appendages — of wheat, barley, and other cereal grains that signal their ripeness, while 种 (zhòng) means "to plant.
Summer Solstice
On the longest day of the year, when the sun climbs to its highest point in the northern sky and daylight stretches far into evening, China observes Xiazhi — the Summer Solstice. Occurring around June 21st or 22nd, this tenth solar term marks the official peak of summer, the moment when yang energy reaches its absolute maximum.
Minor Heat
Minor Heat (小暑, Xiǎoshǔ) arrives as the eleventh solar term in the Chinese calendar, typically falling between July 6th and 8th. Despite its name suggesting "minor" or "lesser" heat, Xiaoshu marks the true beginning of the hottest period of the year — the onset of the infamous 三伏天 (sānfútiān), or "three periods of hiding," when the combination of temperature and humidity reaches levels that the ancient Chinese considered genuinely dangerous.
Major Heat
Major Heat (大暑, Dàshǔ) arrives as the twelfth solar term and the climatic climax of the Chinese year, typically falling between July 22nd and 24th. As the name declares — 大 (dà) meaning "great" or "major," and 暑 (shǔ) meaning "heat" — this is the hottest period of the entire annual cycle, when the sun's energy, accumulated through months of lengthening days, reaches its absolute peak.
Beginning of Autumn
There is a particular moment in the Chinese calendar, usually around August 7th or 8th, when the air changes. It is still hot — sometimes oppressively so — but something has shifted.
End of Heat
Among the twenty-four solar terms, none marks a more welcome transition than Chushu (处暑), the End of Heat. Arriving annually between August 22nd and 24th, this fourteenth solar term signals the moment when the oppressive humidity and scorching temperatures of the summer months finally begin their long retreat.
Autumn Equinox
The Autumn Equinox (秋分, Qiūfēn) arrives as one of the most perfectly balanced moments in the entire annual cycle — the sixteenth solar term, when day and night once again stand as equals, as they did six months earlier at the Spring Equinox. Falling between September 22nd and 24th, Qiufen marks the exact midpoint of autumn, the pivot upon which the season turns from early golden warmth toward the crisp chill of late autumn.
White Dew
There is a morning in early September when you step outside and see the world transformed. Every blade of grass wears a crystalline droplet.
Cold Dew
Cold Dew (寒露, Hánlù) arrives as the seventeenth solar term, marking the moment when autumn's gentle coolness sharpens into genuine cold. Falling around October 8th or 9th, Hanlu is the first solar term to carry the character 寒 (hán) — "cold" — in its name, a linguistic signal that the season has crossed a threshold.
Frost's Descent
When the morning grass crunches underfoot and a crystalline layer coats the autumn chrysanthemums, the Chinese calendar declares Shuangjiang — Frost's Descent. Arriving around October 23rd or 24th, this eighteenth solar term is the last of autumn, the final pause before winter's arrival.
Beginning of Winter
The Beginning of Winter (立冬, Lìdōng) arrives as the nineteenth solar term, the official threshold between autumn's golden decline and winter's stark dominion. Falling annually around November 7th or 8th, Lidong carries profound weight in the Chinese calendar — it is the moment when the year's energy, having spent itself in the exuberant growth of spring and summer and the gathering harvest of autumn, turns definitively inward.
Minor Snow
There is a particular quality to the first snow of winter — a gentleness that the blizzards of deep winter lack. The flakes drift rather than drive, settle rather than smother, and transform the world without violence.
Major Snow
Major Snow (大雪, Dàxuě) arrives as the twenty-first solar term, the moment when winter's grip tightens and the world begins its transformation into a landscape of white. Falling annually between December 6th and 8th, Daxue marks the period when snowfall becomes heavy and sustained, when the ground stays white from one storm to the next, and when the full, silent beauty of deep winter settles over the land.
Winter Solstice
The Winter Solstice (冬至, Dōngzhì) stands as one of the most significant moments in the entire Chinese calendar — the twenty-second solar term, when the northern hemisphere experiences its shortest day and longest night. Falling annually between December 21st and 23rd, Dongzhi represents the extreme of yin energy, the moment when darkness reaches its maximum dominion and the sun appears at its lowest point in the sky.
Minor Cold
Minor Cold (小寒, Xiǎohán) arrives as the twenty-third solar term, and despite its diminutive name, it often brings the most bitter cold of the entire year. Falling annually between January 5th and 7th, Xiaohan marks the period when winter reaches its deepest intensity — when the wind cuts like a knife, when breath crystallizes in the air, and when the frozen earth seems to hold its breath, waiting for the distant promise of spring.
Major Cold
In the depths of winter, when the northern winds cut like blades and the sun seems a distant memory, the Chinese calendar reaches its coldest point: Dahan, the Great Cold. Arriving around January 20th or 21st, this twenty-fourth and final solar term represents winter at its most absolute.
