Having a period (menstration) is the major change that happens to a girl during puberty. Just as becoming able to ejaculate semen is the major change for a boy. Just like puberty in boys puberty is girls is very variable and different girls will have their first period at different ages. The average age at which girls begin puberty is 11 or 12 years of age. Once a girl has started having her periods she usually has one once every 28 days.
