Dano, also called Surit-nal, is a Korean traditional holiday that falls on the 5th day of the fifth month of the lunar Korean calendar. It is an official holiday in North Korea and one of the major traditional holidays in South Korea.

In the Mahan confederacy of ancient Korea, this was a day of spiritual rites, and enjoyment with song, dance, and wine. Traditionally, women washed their hair in water boiled with Sweet Flag (changpo), believed to make one's hair shiny. People wore blue and red clothes and dyed hairpins red with the iris roots. Men wore iris roots around their waist to ward off evil spirits. Herbs wet with dew on this morning were said to heal stomachaches and wounds. Traditional foods include surichitteok, ssuktteok, and other herb rice cakes.

The persisting folk games of Dano are the swing and ssireum. The swing was a game played by women, while ssireum was a wrestling match among men. In addition, mask dance used to be popular among peasants due to its penchant for satirical lyrics flouting local aristocrats.
