1. What is the Due Date Calculator?

The Due Date Calculator estimates how many weeks pregnant you are based on your due date and the current date. It helps track pregnancy progress and determine if you're overdue.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Due Date — Estimated date of delivery (typically 40 weeks from last menstrual period)
• Current Date — Today's date or any date you want to check

Explanation: The calculation counts backwards from the due date to determine how many weeks pregnant you are at any given date.

3. Importance of Pregnancy Dating

Details: Accurate pregnancy dating is crucial for proper prenatal care, scheduling tests at appropriate times, and identifying potential complications like preterm labor or post-term pregnancy.

4. Using the Calculator

Tips: Enter your due date (usually provided by your healthcare provider) and the current date to calculate how many weeks pregnant you are. If the current date is after your due date, it will show how many weeks overdue you are.
