How is the due date calculated?

The standard estimate is based on 40 weeks of pregnancy counted from the first day of the last menstrual period. If the cycle length differs from 28 days, this calculator makes a calendar adjustment.

Why can the date change?

Your healthcare professional may confirm or revise pregnancy dating using an ultrasound, particularly when the last menstrual period is uncertain.
