1. What is the How Far Along Calculator?

The How Far Along Calculator estimates the current gestational age of a pregnancy based on the due date and today's date. It helps pregnant individuals track their pregnancy progress and understand how many weeks and days they have completed.

2. How Does the Calculator Work?

The calculator uses the pregnancy dating formula:

Where:

• \( \text{Due Date} \) — Estimated date of delivery
• \( \text{Today} \) — Current date
• \( 7 \) — Days per week conversion factor

Explanation: The calculation assumes a standard 40-week (280-day) pregnancy duration and calculates how much time has passed since conception.

3. Importance of Pregnancy Dating

Details: Accurate pregnancy dating is essential for proper prenatal care, monitoring fetal development, scheduling important tests, and determining the optimal time for delivery.

4. Using the Calculator

Tips: Enter your due date (as provided by your healthcare provider) and today's date. The calculator will display your current gestational age in weeks and days.
