Pregnancy Due Date Calculator
Estimate your due date and pregnancy milestones based on your last menstrual period.
How It Works
- • Due date is estimated as LMP + 280 days (40 weeks), following Naegele's rule.
- • Conception is assumed to occur around LMP + 14 days.
- • Trimesters: 1st (weeks 1–13), 2nd (weeks 14–27), 3rd (weeks 28–40).
- • Only an estimate — your healthcare provider can give a more accurate date via ultrasound.
