1. What is Pregnancy Due Date Calculation?

The Pregnancy Due Date Calculator estimates the expected delivery date based on the day of conception. Using the standard formula of conception date plus 266 days, it provides an accurate estimation of when the baby is likely to be born.

2. How Does the Calculator Work?

The calculator uses the pregnancy due date formula:

Where:

• \( EDD \) — Estimated Due Date
• \( Day\ of\ Conception \) — The known date of conception
• \( 266\ days \) — Standard gestation period from conception

Explanation: This calculation assumes a standard 266-day gestation period from conception to delivery, which corresponds to approximately 38 weeks of pregnancy.

3. Importance of Due Date Calculation

Details: Accurate due date calculation is crucial for prenatal care planning, monitoring fetal development, preparing for delivery, and ensuring appropriate medical interventions throughout pregnancy.

4. Using the Calculator

Tips: Enter the exact date of conception. The calculator will automatically compute the estimated due date by adding 266 days to the conception date.
