My menstrual calculator

My menstrual calculator is simple and pleasant to use.
The calculator only estimates the monthly menstruation cycle, but does it well.

Contrary to others calendars, you only need your cycle start date and the cycle time (average 28 days) to configure it.
And the calendar will show you your futures menstruals periods and ovulation.

Couples who are expecting a child can find the good periods. It is also especially useful for those who want to plan a weekend getaway or a weekend of sports. Finally, it will be useful to men who want to offer an evening to his wife, mistress, concubine or other.
