Add 280 days (40 weeks) to the first day of your last menstrual period. Our calculator does this automatically.
When can I find out my baby's gender?
Gender can typically be determined between 18-22 weeks via ultrasound, or as early as 10 weeks with NIPT testing.
Is my due date accurate?
Only about 5% of babies are born on their due date. Most are born within a 2-week window before or after.
