1. What is Pregnancy Week Calculator?

The Pregnancy Week Calculator estimates how far along you are in your pregnancy based on your due date and current date. It helps expectant mothers track their pregnancy progress in weeks.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• 40 — Standard length of pregnancy in weeks
• Due Date — Estimated date of delivery
• Current Date — Today's date
• 7 — Days in a week

Explanation: The calculation shows how many weeks remain until the due date (if positive) or how many weeks have passed since the due date (if negative).

3. Importance of Tracking Pregnancy Weeks

Details: Tracking pregnancy weeks helps monitor fetal development, schedule prenatal appointments, and prepare for delivery. Medical care often varies by trimester and specific week of pregnancy.

4. Using the Calculator

Tips: Enter your due date (from ultrasound or last menstrual period) and current date (defaults to today). The calculator will show your current pregnancy week.
