Our Mission

Ovulation Date Calculator is designed to help women understand their menstrual cycles and identify their most fertile days. Our goal is to provide a simple, accurate, and easy-to-use tool that empowers women to make informed decisions about their reproductive health.

How It Works

Our calculator uses established medical knowledge about menstrual cycles to estimate ovulation dates. The tool calculates your fertile window based on:

  • The first day of your last menstrual period
  • Your average cycle length
  • Standard ovulation patterns (typically 14 days before the next period)

What We Calculate

Ovulation Window

The 2-3 day period when you're most likely to ovulate, based on your cycle length.

Most Likely Conception Date

The peak fertility day when conception is most likely to occur.

Fertile Week Range

An extended period of fertility that accounts for sperm survival and egg viability.

Privacy & Security

We prioritize your privacy. Our calculator operates entirely within your browser - no personal data is transmitted to our servers. Your cycle information stays private and is not stored or shared with third parties.
