Frequently asked questions
How is a due date calculated?
Due dates are typically estimated as 280 days (40 weeks) from the first day of the last menstrual period, or measured via ultrasound. Enter the due date your provider gave you for the most accurate countdown.
Will the baby arrive exactly on the due date?
Only about 1 in 20 babies arrives on the exact due date — most arrive within two weeks either side. Treat the countdown as an estimate, not a promise!
