Random Acts of Kindness Day is the name of an unofficial holiday increasingly celebrated around the world by localities or organizations, or nationwide, in order to encourage acts of kindness. The original founder of Random Acts of Kindness Day is unknown.^{[citation needed]}.

The holiday is celebrated annually in the United States on February 17 and in New Zealand on September 1.^[1] In New Zealand, RAK day began at a national level in 2005^[2] by Josh de Jong, Marshall Gray, Megan Singleton and Reuben Gwyn. It is not a holiday, rather a national day where the entire country is challenged to do something kind to a friend or stranger for no reason at all.

The Ghost Festival, also known as the Hungry Ghost Festival, or Yu Lan is a traditional Chinese festival and holiday celebrated by Chinese in many countries. In the Chinese calendar (a lunisolar calendar), the Ghost Festival is on the 15th night of the seventh lunar month (14th in southern China).

In Chinese tradition, the fifteenth day of the seventh month in the lunar calendar is called Ghost Day and the seventh month in general is regarded as the Ghost Month (鬼月), in which ghosts and spirits, including those of the deceased ancestors, come out from the lower realm. Distinct from both the Qingming Festival (in Spring) and Chung Yeung Festival (in Autumn) in which living descendants pay homage to their deceased ancestors, on Ghost Day, the deceased are believed to visit the living.
