1. What is Pregnancy Due Date Calculator?

The Pregnancy Due Date Calculator estimates the expected delivery date (EDD) based on the conception date. It uses the standard calculation of conception date plus 266 days to determine the estimated due date.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

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

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

3. Importance of Due Date Calculation

Details: Accurate due date calculation is essential for proper prenatal care, monitoring fetal development, and planning for delivery. It helps healthcare providers track pregnancy progress and identify potential complications.
