Due Date Calculator

This is basic tool, for a basic due date estimate. This is based soley on a 40 week pregnancy from your Last menstrual period, if you have a classic 28 day cycle. This may change as your individual history is taken into account – but it will get you in the ball park! If you can not see the calculator below – click the “Compatibility” in your browser bar ( looks like a piece of paper broken in half on the right side of your address bar).
