Ovulation Date Calculator

Ovulation Date Calculator

A woman is able to become pregnant (fertile) only during a certain part of her monthly
cycle. That is just before and during ovulation. By learning when you ovulate, you
can predict when you’re likely to be fertile. This calculator gives approximate ovulation
dates and fertile times for women who have regular periods. (Regular periods mean
having a period every 21 to 35 days.) Fertility charting, basal temperature tracking,
and purchased ovulation test kits can also be used to help predict a woman’s fertile
times. These are especially useful if a woman has irregular periods.

Please note that the date you enter in the calculator may result in an ovulation date
that has already passed. This will occur if you are nearing your next menstrual start

not be used as an aid to preventing pregnancy. This calculator is provided for educational
