Formula Used

Due Date Calculation

The calculator uses the standard 40-week pregnancy period to calculate the due date. The formula is:

Due Date = Last Menstrual Period + 280 days

Where 280 days represents the average length of a full-term pregnancy (40 weeks × 7 days/week).

Note

Every pregnancy is unique, and due dates are estimates. Actual delivery dates may vary by several days or weeks.

Example Calculation

Let's say your last menstrual period was on January 1, 2023. Using the formula:

Due Date = January 1, 2023 + 280 days = October 8, 2023

This means your estimated due date would be October 8, 2023, assuming a full-term pregnancy.

The calculator will also show you important milestones leading up to your due date, such as:

First trimester: Weeks 1-12
Second trimester: Weeks 13-28
Third trimester: Weeks 29-40
