What this means for your baby’s birthday

A March conception gives due dates from November 22, 2027 to December 22, 2027. Because most babies are born within about two weeks of the due date, the actual birthday could fall in the month before or after. Conception dates are rarely known exactly: if you are working from intercourse dates, conception may have happened a few days later.
