A pregnancy week calculator converts between gestational age (weeks from last menstrual period) and calendar dates to determine due dates, trimester boundaries, and developmental milestones. The estimated due date is 40 weeks (280 days) from the last menstrual period; only 5% of babies are born on their exact due date.
