1 Work out the length of your average menstrual cycle. Day one is the first day of the menstrual period and the last day is the day before the next period begins.  Ovulation happens about two weeks before the next expected period. So if your average menstrual cycle is 28 days, you ovulate around day 14.
To convert a time to its decimal value, divide the hours (using the 24-hour clock) by 24 (the number of hours in a full day): 1  12:00:00 PM (Noon) is exactly halfway through the day, so the decimal value is 1 / 2 = 0.5. 2  6:00:00 AM is one-fourth of the day, so the decimal value is 1 / 4 = 0.25.
