Summer Solstice (夏至)
The Summer Solstice is one of the twenty-four solar terms and the longest day of the year. After it, the daylight slowly grows shorter.
At a glance
What the solar terms mean
Summer Solstice usually falls on 21 June in the Western calendar; in 2026, 2027 and 2028 it also falls on 21 June. On this day the Sun shines directly over the Tropic of Cancer, its northernmost reach, so the Northern Hemisphere enjoys its longest daylight.
'Zhi' (至) means the extreme point. The day is longest, but not yet the hottest; the peak heat waits for Lesser Heat and Greater Heat, the last two solar terms of summer. In traditional thought, yang energy reaches its height now, while yin quietly begins to grow — 'yang at its extreme gives rise to yin' (陽極陰生).
Traditional customs in different places
A folk saying pairs the solstices: 'wontons at the Winter Solstice, noodles at the Summer Solstice' (冬至餛飩夏至麵). The new wheat is gathered around this time, so a bowl of noodles tastes the fresh harvest and marks the season. In northern China, many enjoy noodles cooled after boiling; in the Jiangnan region and in Taiwan, some prefer cold noodles or soup noodles. Many overseas Chinese families keep the habit as well. Each place has its own way, yet the heart is the same: living in tune with the season.
