Frequently asked questions
Is this the same method doctors use?
It uses the standard 280-day (40-week) estimate from the last menstrual period, the same baseline method commonly used, though a care provider may adjust the date based on an ultrasound.
Is this medical advice?
No. This is a general estimate for planning purposes, not medical advice. Follow your care provider’s guidance for your actual due date and prenatal care.
Can I calculate from a known conception date instead?
Yes, the tool supports estimating from either the last period date or a known conception date.
