How Conception-Based Due Dates Work
Pregnancy is typically dated at 38 weeks (266 days) from conception. If you know your conception date, this calculator estimates the due date by adding 266 days.
Always confirm due dates with your healthcare provider, as ultrasound measurements may adjust this estimate.
