1. What Is Pregnancy Calculator From Conception Date?

The Pregnancy Calculator From Conception Date estimates the due date based on the known conception date using the standard formula of adding 266 days to the conception date.

The calculator uses the pregnancy due date formula:

Where:

• \( EDD \) — Estimated Due Date
• \( Conception Date \) — 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 EDD Calculation

Details: Accurate due date estimation is crucial for prenatal care planning, monitoring fetal development, preparing for delivery, and scheduling important medical tests and appointments throughout pregnancy.
