primarily for males, particularly with regard to technical education. For example, prestigious engineering schools, such as École Polytechnique, did not allow women until the 1970s. "Coming of age" customs Many cultures have traditional customs to mark the "coming of age" of a girl or boy, to recognize their transition to adulthood, or to mark other milestones of their journey to maturity as children. Japan has a coming-of-age ritual called Shichi-Go-San (七五三), which literally means "Seven-Five-Three". This is a traditional rite of passage and festival day in Japan for three- and seven-year-old girls and three- and five-year-old boys, held annually on November 15.

Confirmation is a ceremony common to many Christian denominations for both boys and girls, usually taking place when the child is in their teen years. In Roman Catholic communities, Confirmation ceremonies are considered one of seven sacraments that a Catholic may receive during their life. In many countries, it is traditional for Catholics children to undergo another sacrament, First Communion, at the age of 7 years old. The sacrament is usually performed in a church once a year, with children who are of age receive a blessing from a Bishop in a
