1. What is the Baby Week Calculator?

The Baby Week Calculator estimates either how many weeks pregnant you are (before due date) or how many weeks old your baby is (after due date) based on the due date and current date.

2. How Does the Calculator Work?

The calculator uses the following calculation:

Where:

• \( Due\ Date \) — The expected date of delivery
• \( Current\ Date \) — Today's date or any date you want to check

Explanation: The calculator determines the difference in days between the two dates, then converts to weeks by dividing by 7.

3. Importance of Pregnancy Week Calculation

Details: Knowing exactly how many weeks pregnant you are is crucial for proper prenatal care, tracking fetal development milestones, and scheduling important medical tests.

4. Using the Calculator

Tips: Enter your due date and the current date (defaults to today). The calculator will show either how many weeks pregnant you are (before due date) or how many weeks old your baby is (after due date).

Q4: What if my baby is born before or after the due date?
A: The calculator will automatically adjust to show the baby's age in weeks once the current date passes the due date.

Q5: Can I use this for twins or multiples?
