Due Date Calculator:
The Due Date Calculator uses the Naegelé’s Rule to estimate when your baby is likely to be born. By entering the first day of your last period or date of conception, it automatically calculates your expected delivery date (EDD), current gestational week, and trimester stage, helping you monitor pregnancy progress.

Testing and Final Adjustments
Verify accuracy by using sample measurements from Army fitness charts. Ensure error handling for missing or unrealistic values. Optimize mobile and desktop usability, and highlight results with clear categories (e.g., “Excellent,” “Acceptable,” “Fail”). Include a disclaimer that results are estimates and not a medical diagnosis. Periodically update formulas to match current Army standards. Provide optional guidance on reducing body fat safely. Incorporate low-competition keywords naturally in headings, meta tags, and descriptions to improve SEO visibility. Ensure that units are flexible (inches/cm, pounds/kg) for international users.
