1. What is Due Date Calculation?

Due date calculation estimates the expected delivery date based on the current stage of pregnancy. It helps healthcare providers and expectant parents plan for the arrival of the baby and monitor pregnancy progress.

2. How Does the Calculator Work?

The calculator uses the standard pregnancy duration formula:

Where:

• \( EDD \) — Estimated Due Date
• \( Current Date \) — Today's date or specified date
• \( Current Weeks \) — Number of weeks pregnant
• \( 40 \) — Standard full-term pregnancy duration in weeks
• \( 7 \) — Days per week

Explanation: The calculation assumes a standard 40-week pregnancy and calculates the remaining time until the due date.

3. Importance of Due Date Estimation

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 and your current weeks of pregnancy (typically confirmed by ultrasound or last menstrual period). The calculator will determine your estimated due date.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this due date calculation?
A: This calculation provides an estimate based on standard 40-week pregnancy. Actual delivery dates may vary by ±2 weeks.

Q2: What if I know my conception date?
A: Due date can also be calculated by adding 38 weeks (266 days) to the conception date.

Q3: Why is 40 weeks used as standard?
A: 40 weeks is the medically accepted duration for full-term pregnancy, calculated from the first day of the last menstrual period.

Q4: Can due dates change during pregnancy?
A: Yes, due dates may be adjusted based on ultrasound measurements, especially if early ultrasounds differ significantly from LMP-based calculations.

Q5: What percentage of babies are born on their due date?
A: Only about 5% of babies are born exactly on their due date. Most are born within two weeks before or after.
