This interactive tool calculates your pregnancy due date, an estimate of when you are likely to deliver your baby.

To find your due date, the calculator takes the first day of your last menstrual period (LMP) and adds 40 weeks. If you are planning a pregnancy, you can use this calculator to plan the birth for a certain month or season.
