🤰 Pregnancy Due Date Calculator
Calculate your estimated due date based on your last menstrual period
Understanding Your Due Date
Your due date is calculated as 280 days (40 weeks) from the first day of your last menstrual period. This assumes a typical 28-day menstrual cycle with ovulation occurring around day 14.
Important: This is just an estimate. Only about 5% of babies are born on their exact due date. Most babies arrive between 37 and 42 weeks of pregnancy.
