Due Date Calculator

A due date from last menstrual period is a planning anchor that your provider may move after an early ultrasound, especially with irregular cycles. The calculator adds the usual 280 days from a chosen LMP and shows trimester boundaries. Medical decisions belong with your prenatal care team, not a website alone, when dates matter clinically.
