Due Date Calculator

Calculate your expected due date by inserting the date of the first day of your last menstrual period in the calculator.

1. What was the first day of your last period?
2. How many days in your menstrual cycle?

This is an estimation only of your baby's due date. Very few babies will actually be born on their expected due date.

On your first appointment with David, he will advise you of your estimated due date.
