lunar cycle
Waxing and waning
A lunar cycle is the period from one new moon to the next—approximately 29.5 days during which the moon passes through all its phases: new, waxing crescent, first quarter, waxing gibbous, full, waning gibbous, last quarter, and waning crescent.
The term applies to any complete sequence of lunar phases.
Her menstrual cycle roughly follows the lunar cycle.
