Ovulation means a time when the woman is fertile enough to get pregnant. That is the common definition known by people.One of the most common method used to predict ovulation is calendar based method, the method that is based on a record of the length of previous menstrual cycles, as originally developed by John Smulders in 1930.
This yearly ovulation calendar is a simple calendar which will map the method in one full year. This calendar will work best for women who have regular menstruation.

How to use:
- This is a one worksheet calendar. Fill the setup information on top of this worksheet to reveal your ovulation dates,
- Type the starting date of your last menstrual cycle in cell H4,
- Type the length of your menstrual cycle period in cell H5,
- Type your luteal phase period in cell H6. Luteal phase also referred to as ‘days past ovulation’ or ‘DPO’, is the part of the cycle that starts at ovulation and ends the day before your next period. It usually lasts about 14 days and does not vary by more than a day in each person,
- Type the year you want to see your ovulation dates in cell O4. You can only see the next 30 ovulation dates in the calendar. I recommend you to fill the year with the same year of your last menstrual cycle year,
- Filling the start day cell at O5 is optional. You can adjust the calendar to start its week with Monday or Sunday by selecting those days in that cell,
- Check your calendar. Because this calendar is based on statistic, your fertility dates could be different with the dates marked in this calendar. It could be around 3 days before or after that dates. Remember to use it as your side reference only,
