The calendar method, also known as the rhythm method, involves tracking menstrual cycles to estimate when ovulation occurs. Women with perfectly regular cycles can typically estimate ovulation by subtracting 14 days from their cycle length (e.g. if a woman has a 28-day cycle, ovulation is likely to occur around day 14). In order to use the calendar method effectively as a means of birth control, couples should abstain from intercourse for at least 8 days before and after the estimated date of ovulation. This is because sperm can survive for up to 5 days in the female reproductive tract, and there is some variation in the timing of ovulation from cycle to cycle.
