cycle binary package in Ubuntu Bionic amd64

 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. It allows the user to write notes and
 helps to supervise the administration of hormonal contraceptive tablets.

   - Calculate days of menstruation, based on the length of the cycle or

 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.
