Calculating Your Menstrual Cycle Length
To calculate when you ovulate, you need to know how many days are in your menstrual cycle. Your menstrual cycle length is the number of days between when your period started to the day before the next period starts.
If you already know your menstrual cycle length, scroll down and enter your information!
If you don't want to manually figure out the length, you can just click here. All you need is the start dates of your last two periods. We will calculate your cycle length for you.
Calendar Limitations
- Cycle lengths of more than 35 days are too long for appropriate calculations.
- Cycle lengths of less than 21 days are too short for appropriate calculations.
