1. What is Due Date Calculation?

Due date calculation estimates the expected delivery date based on current pregnancy week. It helps healthcare providers and expectant parents plan for childbirth and monitor pregnancy progress.

2. How Does the Calculator Work?

The calculator uses the standard due date formula:

Where:

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

Explanation: The formula calculates remaining weeks until full term (40 weeks) and converts them to days to determine the estimated delivery date.

3. Importance of Due Date Estimation

Details: Accurate due date estimation is crucial for prenatal care planning, fetal development monitoring, and preparing for delivery. It helps identify potential preterm or post-term pregnancies.

4. Using the Calculator

Tips: Enter current date and weeks pregnant (0.1 to 42 weeks). The calculator will estimate your due date based on standard 40-week pregnancy duration.

5. Frequently Asked Questions (FAQ)

Q1: Why is 40 weeks used as full term?
A: 40 weeks is the standard duration for full-term pregnancy, calculated from the first day of the last menstrual period (LMP).

Q2: How accurate is this calculation?
A: This provides a general estimate. Ultrasound measurements in early pregnancy typically provide more accurate due dates.

Q3: What if my pregnancy is measured from conception?
A: Conception-based dating is typically 2 weeks less than LMP-based dating. Adjust weeks pregnant accordingly.

Q4: Can due dates change during pregnancy?
A: Yes, healthcare providers may adjust due dates based on ultrasound findings and fetal growth measurements.

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 2 weeks before or after.
