How the date is worked out
The Chinese calendar begins each month at the new moon, as seen in China’s time zone. The Dragon Boat Festival, Duanwu, is the fifth day of the fifth month, early in the summer.
How it’s celebrated
Teams race long boats with dragon heads to the beat of a drum, and families eat zongzi, sticky rice wrapped in bamboo leaves. The festival is told to remember the poet Qu Yuan, who drowned himself in the Miluo River.
