How the Due Date is Calculated

The standard pregnancy duration is 40 weeks (280 days) from the first day of your last menstrual period. Our calculator uses this standard to estimate your due date.

Due Date = Last Menstrual Period + 280 days

For example, if your last menstrual period was on January 1, 2023, your due date would be October 31, 2023 (280 days later).

If you have an ultrasound date, we recommend using that instead of your last menstrual period date for more accurate results.

Understanding Pregnancy Timeline

The pregnancy timeline is divided into three trimesters:

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

Each trimester has its own set of milestones and considerations. Our calculator helps you track your progress through each stage of pregnancy.
