1. What is EDD Preg Conception?

The EDD Preg Conception (Estimated Due Date from Conception) calculator determines the expected delivery date by adding 266 days to the known conception date. This method provides an accurate due date calculation when the exact conception date is known.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

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

Explanation: This calculation is based on the average human gestation period of 266 days (38 weeks) from conception to delivery.

3. Importance of Due Date Calculation

Details: Accurate due date calculation is essential for proper prenatal care, monitoring fetal development, planning for delivery, and ensuring optimal timing for medical interventions when needed.

4. Using the Calculator

Tips: Enter the exact conception date in the date field. The calculator will automatically compute and display the estimated due date 266 days later.
