Puberty in Hinduism
https://en.wikipedia.org/wiki/Ritu_Kala_Samskaram
Although somewhat archaic, some Hindu communities still celebrate a girl’s first period with a celebration to announce her fertility and coming of age. Many young girls were deemed ready for marriage and wifely duties at this time (which I find rather horrifying). Depending on the community, determined what ritual events took place, from isolation to large lavish parties.
