Frequently asked questions
How accurate is the due date calculator?
It uses the standard method (280 days from your last period, or from conception) that clinicians use for an estimated due date. Only about 1 in 20 babies arrive on the exact date.
Are these medical tools?
No — they are informational estimates. For personal medical decisions, always consult a qualified healthcare professional.
