Pregnancy Due Date Calculator
Medical Tip: Only about 5% of babies are born on their exact due date. Most arrive within 2 weeks before or after.
- LMP: Last Menstrual Period (first day of bleeding)
- EDD: Estimated Due Date (40 weeks from LMP)
- Trimester: Pregnancy divided into 3-month periods
***Note: This calculator uses Naegele's rule (LMP + 280 days). Ultrasound dating may provide more accurate results. Always consult your OB/GYN.
Enter the first day of your last period (not ovulation date)
