Moon Mapping
Moon + Cycle Energy Calculator
See where your menstrual cycle and the lunar cycle meet. Choose any date, past or future, and discover where you may be in your menstrual cycle alongside the lunar cycle. See whether the two rhythms are building together, moving inward together, or creating a completely different kind of energy between them.
Defaults to today. Choose another date to look ahead or back.
Today’s lunar day will appear here.
For the most accurate estimate, enter the first day of your most recent period, or the most accurate cycle date you know for the date you’re checking. The calculator assumes a 29-day menstrual cycle when estimating past and future dates.
Leave blank if you do not have a menstrual cycle.
Your menstrual cycle day will appear here.
This gives you something to compare with the generalized pattern.
When either manual field contains a number, the calculator uses the manual cycle day instead of the date calculation.

This is a reflective planning tool, not a medical prediction. Menstrual-cycle experiences vary widely. Lunar day is calculated from a standard astronomical lunar-month approximation; exact phase timing can shift the boundary of a cycle day.
