1. What is the Pregnancy Week Calculator?

The Pregnancy Week Calculator estimates how many weeks remain until your due date and calculates your current pregnancy week based on the standard 40-week pregnancy duration.

2. How Does the Calculator Work?

The calculator uses the following calculation:

Where:

• Due Date — Your estimated delivery date
• Current Date — Today's date or any date you want to check

Explanation: The calculator determines the days remaining until your due date and converts them to weeks by dividing by 7. Your current pregnancy week is calculated by subtracting weeks remaining from 40 (standard pregnancy duration).

3. Importance of Pregnancy Week Tracking

Details: Tracking pregnancy weeks helps monitor fetal development, schedule important prenatal tests at the right times, and prepare for delivery. Each week of pregnancy has specific developmental milestones.

4. Using the Calculator

Tips: Enter your due date and the current date (defaults to today). The calculator will show weeks remaining until delivery and your current pregnancy week.
