Due Date Calculator

Enter the first day of your last period. If you are not sure of the precise date, estimate it as closely as possible. The calculator will approximate the date of ovulation and the due date of your baby. Keep in mind that this is simply an estimate; always consult your physician or another health care professional to more accurately assess your due date.

If you think you are pregnant, it is important that you contact your physician or another health care professional immediately.
