The Dragon Boat Festival (Duanwu Festival, Double Fifth, and Tuen Ng Jit) is a traditional holiday that commemorates the life and death of the famous Chinese scholar Qu Yuan (Chu Yuan). The festival occurs on the fifth day of the fifth month on the Chinese lunar calendar.

Falling on the 5th day of the 5th month according to Chinese lunar calendar, the Dragon Boat Festival is one of great significance. It has been held annually for more than 2,000 years and is notable for its educational influence. The festival commemorates the patriotic poet Qu Yuan (340-278 BC), and also acts as a chance for Chinese people to build their bodies and dispel diseases. Many legends circulate around the festival but the most popular is the legend of Qu Yuan.

The festival was long marked as a cultural holiday in China. However, it wasn’t until 2008 that the Dragon Boat Festival was recognized as a traditional and statutory public holiday in the People's Republic of China.

The sun is considered to be at its strongest around the time of summer solstice ("mid-summer" in traditional East Asia, but "beginning" of summer elsewhere) when the daylight in the northern hemisphere is the longest. The sun, like the Chinese dragon, traditionally represents masculine energy, whereas the moon, like the phoenix, traditionally represents feminine energy. The summer solstice is considered the peak annual moment of male energy.
