• Use this Online Fertility Calculator to determine your peak fertility dates.

  • You can choose to get the fertile days for the next 3 months to over the next 1 year.

  • This can be especially helpful for couples that need to time "baby-making sex".

  • Once you have the dates, you can set up FREE EMAIL REMINDERS , and even pay a small fee to receive SMS's alerting you on your fertile days ( at the moment, this service is available only in India)

  • The Calculator calculates your most fertile days based on the fact that:
    1. Ovulation occurs 14 days before the next menstrual period is due.
    2. Fertility peaks on the day of ovulation and for 4 days prior to this.
