Ovulation Calculator

Knowing the ovulation period can help increase chances of conception. During this time the sperm meets and fertilizes the egg.

Ovulation usually occurs 14 days after the first day of menstrual cycle. After ovulation, the egg can be fertilized up to 24 hours. The chances of conception are very high during this period.

While a sperm can fertilize eggs for up to 5 days, an egg is expected to be productive for 24-48 hrs after they are released. Therefore the fertile period starts around 3-5 days before ovulation and lasts around 24 hrs after the ovulation.

While this tool is used to calculate approximate date of ovulation to help in pregnancy, various individual conditions including personal health may have an impact on actual date of ovulation.
