health.menstrual-cycle Calculator
Tracks menstrual cycle length and predicts the next period date, ovulation window, and fertile days based on a running average of recent cycle lengths. Cycle length varies naturally by 2–7 days — averaging several cycles improves prediction accuracy.
Inputs
Start
Time for one complete cycle (s). Period = 1 / frequency. A 50 Hz signal has a 20 ms period.
Cycle
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Period
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Lut
Reference formula or conversion factor shown for context.
Results
current phase
Electric charge flow rate (A). Governs wire sizing — too much current causes dangerous heating. Fuses protect circuits from overcurrent.
day of cycle
Reference formula or conversion factor shown for context.
days until ovulation
The value at the specified point or condition.
days until next period
Sample size or count used in the calculation.
phase duration
Weighted average time to receive the bond's cash flows (years). Also a price sensitivity measure: duration of 7 means a 1% rise in yields drops the bond price ~7%.
