The term "menstruation" comes from the Latin word mensis (month), which in turn relates to the Greek word mene (moon).
The English words month and moon also come from the Latin mensis, reflecting the fact that the moon’s period of revolution around the earth, 27days, is similar to that of the human menstrual cycle.
The term “ritual” is derived from the Sanskrit word "R’tu", which means “menstrual”.
The word “taboo” comes from the ancient Plynesian word "tapua," meaning both menstruation and sacred.
It is said that when Australian Woman’s Weekly went to a monthly format in 1982, Kerry Packer vetoed a name change to Australian Women’s Monthly for obvious reasons. It remains published under its weekly name.
