Quick FAQs
How is a due date usually calculated?
Most tools estimate ~40 weeks (280 days) from the first day of your last menstrual period (LMP), adjusted for cycle length.
Is the due date exact?
No. It’s an estimate. Many births happen within a range, and only a small percentage occur on the exact EDD.
What if I conceived with IVF?
IVF calculators estimate conception based on embryo age and transfer date, then calculate EDD from that—this is included here.
