Enter your details on the left to calculate your pregnancy due date and milestones.

How It Works

The calculator primarily uses a modified version of Naegele's rule to estimate the due date (EDD).

  • By First Day of LMP: We add 280 days (40 weeks) to the first day of your last menstrual period. If your average cycle length is longer or shorter than the standard 28 days, we adjust the due date by that difference.
  • By Conception Date: If you know the exact date of conception, we simply add 266 days (38 weeks) to calculate the estimated due date.

Disclaimer: This tool provides estimates for informational purposes only. Only about 4-5% of babies are born exactly on their estimated due date. Always consult your healthcare provider for medical advice.

Frequently Asked Questions

The Pregnancy Due Date uses established biological and physical formulas to estimate key health metrics, providing a baseline understanding of your fitness or nutritional status.

The Pregnancy Due Date uses standard global formulas (like WHO guidelines). However, generic formulas cannot account for individual variations in muscle mass, bone density, or ethnic genetic differences. It serves as an estimate, not a diagnostic tool.

Never. The Pregnancy Due Date is strictly for informational and educational purposes. You should always consult a licensed healthcare professional before making any significant changes to your diet, exercise, or medical routine.

For tracking trends, using the Pregnancy Due Date once every few weeks under consistent conditions (e.g., same time of day) is generally more useful than daily tracking, which can fluctuate due to hydration and other temporary factors.

If the globally recognized formula for the Pregnancy Due Date requires age and gender inputs to be accurate, those fields will be provided. If not, the metric is universally calculated regardless of demographics.

Yes, your privacy is our priority. The Pregnancy Due Date processes all your data locally on your device. We do not collect, store, or share your personal health inputs.

While the Pregnancy Due Date is useful for the general population, elite athletes often have unique body compositions that require clinical-grade measurements (like DEXA scans) rather than generalized algorithmic estimates.
