1. What is the Due Date Calculator?

The Due Date Calculator estimates the expected delivery date for a pregnancy at 8 weeks gestation. It calculates the due date based on the current date and standard pregnancy duration of 40 weeks.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( EDD \) — Estimated Due Date
• \( CD \) — Current Date
• \( 40 \) — Total weeks of pregnancy
• \( 8 \) — Current weeks pregnant
• \( 7 \) — Days per week

Explanation: The calculation adds the remaining pregnancy duration (32 weeks × 7 days) to the current date to determine the estimated due date.

3. Importance of Due Date Calculation

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

4. Using the Calculator

Tips: Enter the current date when you are 8 weeks pregnant. The calculator will provide the estimated due date based on a 40-week pregnancy duration.
