By convention, estimated delivery occurs 40 weeks after the first day of a last menstrual period for a 28-day cycle. When a conception date is known, an approximate 266-day calculation is often used. Fertility treatments require specific clinical dating methods, so this calculator is not designed for IVF embryo-transfer dates. The clinical due date should be set with a qualified prenatal care professional.
