Cycle is a calendar for women. Given a cycle length or statistics for several periods, it can calculate the days until menstruation, the days of "safe" sex, the fertile period, and the days to ovulations, and define the d.o.b. of a child.

NOTE: This program is not a reliable contraceptive method. It does neither help to prevent sexual transmission diseases like AIDS. It is just an electronic means of keeping track of some of your medical data and extract some statistical conclusions from them. You cannot consider this program as a substitute for your gynecologist in any way.
