just a reminder: we’re two periods away from 2014.
you couldn’t just say months you had to measure time with your menstrual cycle
fUN FACT. the earliest form of a calender that’s ever been found was to keep track of an ancient person’s menstrual cycle. ppl with vaginas invented time. there is a reason that months are about the same length as the time between periods. that is all.
THIS IS SO WRONG.
The earliest form of a calendar was NOT an ancient person’s menstrual cycle. First of all, ancient people DO NOT MENSTRUATE. Menopause happens. They used the cycle of moon phases, being a lunar month between 29 and 30 days.
