Menarche: Archaisms and More!

menarche (n.)

1896, from German menarche (1895), from Greek men (genitive menos) "month" (see moon (n.)) + arkhe "beginning" (see archon).

 

That is to say, the time of a woman's first menstruation.

Please, let Wikipedia educate you:

1. When a Japanese girl has her first period, the family sometimes celebrates by eating red-colored rice and beans (sekihan). The color of blood and the red of sekihan are not related*. All the rice of ancient times of Japan was red. Since rice was precious in ancient Japan (usually, millet was eaten), it was eaten only during the celebration. Sekihan is the tradition of an ancient custom. The celebration is kept a secret from extended family until the rice is served.
2.  In Australia, the Aborigines treat a girl to "love magic". She is taught the ways of womanhood by the other women in her tribe. Her mother builds her a hut to which she confines herself for the remainder of her menses. The hut is burned and she is submerged in the river at the end of menstruation. When she returns to the village, she is paired with a man who will be her husband.
3. In the United States, public schools have a sex education program that teaches girls about menstruation and what to expect at the onset of menarche (often this takes place during the 4th grade). Historically menstruation has been a social taboo and girls were taught about menarche and menstruation by their mothers or a female role model. Then, and to an extent now, menstruation was a private matter and a girl's menarche was not a community phenomenon.**
4. The Ulithi tribe of Micronesia call a girl's menarche kufar. She goes to a menstrual house, where the women bathe her and recite spells. She will have to return to the menstruation hut every time she menstruates***. Her parents build her a private hut that she will live in until she is married
5. The Nuu-chah-nulth (also known as the Nootka) believe that physical endurance is the most important quality in young women. At menarche the girl is taken out to sea and left there to swim back.****
