Pregnancy Due Date Calculator

Calculate pregnancy due date with this free online tool

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.
