1. What is a Due Date Calculator?

The due date calculator estimates when your baby is likely to be born based on your current pregnancy week. At 7 weeks pregnant, the calculator adds 231 days (280 days total pregnancy minus 49 days for 7 weeks) to your current date.

2. How Does the Calculator Work?

The calculator uses the following calculation:

Where:

• 280 days — Standard length of human pregnancy
• 49 days — 7 weeks of pregnancy (7 × 7 days)
• Current Date — Date when calculation is performed

Explanation: Since you're already 7 weeks pregnant, we subtract those 49 days from the total 280-day pregnancy period.

3. Importance of Due Date Calculation

Details: Knowing your estimated due date helps with prenatal care planning, tracking fetal development milestones, and preparing for delivery.

4. Using the Calculator

Tips: Enter the current date (or the date of your last menstrual period if known). The calculator will estimate your due date based on being 7 weeks pregnant.
