How It Works
This calculator uses Naegele's Rule, the standard medical formula for estimating pregnancy due dates:
- Due Date = LMP + 280 days (40 weeks)
- Trimester 1: Weeks 1-12
- Trimester 2: Weeks 13-26
- Trimester 3: Weeks 27-40
Important Notes
- This is an estimate only. Your doctor may adjust the due date based on ultrasound measurements.
- The calculation assumes a regular 28-day menstrual cycle.
- Always consult your healthcare provider for accurate pregnancy assessment.
