Pregnancy Due Date Calculator

How is the Due Date Calculated?

• A full pregnancy typically lasts about 40 weeks, or roughly nine months and seven days. The estimated due date can be calculated from the first day of the last menstrual period by subtracting three months or adding nine months and adding seven days. However, the actual delivery date may differ by one to two weeks from the estimated date. If the last menstrual period date is unknown or irregular, consult a healthcare provider for guidance.
