Pregnancy Due Date Calculator
Calculate your estimated due date, follow pregnancy milestones, and check gestational age using your last period date.
Educational estimate only — not medical advice. A due date is a statistical average, not a fixed appointment, and only about 4% of babies arrive exactly on it. This tool cannot assess you or your baby's health and must not be used to decide when to induce, schedule a procedure, or book any hospital care. Always follow the guidance of your doctor or midwife, and seek medical help immediately for any concerning symptoms.
