Shichi-Go-San

is a traditional Japanese rite of passage and festival day for three- and seven-year-old girls, and five-year-old and sometimes three-year-old boys. It is held annually on November 15 and celebrates the growth and well-being of young children. As it is not a national holiday, it is generally observed on the nearest weekend.

The ages 3, 5, and 7 are consistent with East Asian numerology, which holds that odd numbers are lucky. The practice was set to the fifteenth of the month during the Kamakura period.
