Geburtsterminrechner
Estimate your baby's due date and track pregnancy milestones.
About this tool
Uses Naegele's rule: due date = LMP + 280 days (40 weeks). From conception date, adds 266 days. This gives an estimated due date — only about 5% of babies are born on their exact due date. All calculations happen in your browser.
