Egg of Li Chun

The terms Li Chun egg balancing or egg of Li Chun refers to a Chinese folk belief that it is much easier to balance an egg on a smooth surface during Li Chun (the official first day of spring according to the 24 Chinese solar terms, which usually falls on February 4 or 5), than at any other time of the year. Balancing fresh chicken eggs on their broad end was a traditional Li Chun ritual in China.

This "fact" has come to be widely believed in the United States since 1945, and egg-balancing events are sometimes held on that date. In fact, the balancing of an egg on its broad end is not particularly difficult, at any time of the year.
