Menstrual Cycle Calendar

Menstruation Calendar: How It Works

The length of a woman's menstrual cycle is calculated by the number of days between one menstrual period and the next. The menstual cycle begins on the first day of bleeding and continues up to, but not including, the first day of the next period.

The average for a woman's cycle is 28 days, but it can range anywhere from 21 to 40 days or more. The length of a woman's menstrual cycle may change from month to month.

Ladytimer's Free Menstrual Cycle Calendar is based on the starting day and the cycle length of the women's period. This information is entered once and only needs to be updated if the menstrual cycle becomes irregular.
