Equivalent and related festivals in Asia include the Kodomo no hi in Japan, Dano in Korea, and T?t ?oan Ng? in Vietnam.

The date varies from year to year on the Gregorian calendar. In 2011, this fell on June 6 and in 2012 on June 23. The focus of the celebrations includes eating rice dumplings zongzi, drinking realgar wine xionghuangjiu , and racingdragon boats.
