Find Your Due Date with Our Accurate Due Date Calculator

What is My Due Date?

Your due date, the estimated delivery date, is typically calculated as 280 days from the first day of your last menstrual period, assuming you have regular monthly cycles. Most women give birth within two weeks before or after this estimated date. Only about 1 in 25 pregnant women delivers precisely on their due date.

Using a Due Date Calculator

If your menstrual cycles are regular and you know the first day of your last period, you can estimate your baby's due date and your current stage of pregnancy (gestational age) using an online due date calculator.

Using Ultrasound

If your menstrual cycles are irregular or you're unsure of the start date of your last period, an ultrasound can be used to determine your due date. This should be done as early as possible, as ultrasounds performed after 22 weeks of pregnancy are less accurate for predicting due dates.

Even if you know your last period date and have regular cycles, an ultrasound is often used to confirm the due date. Sometimes, the due date based on the ultrasound differs from the one calculated from your menstrual period. In these cases, healthcare providers usually rely on the ultrasound estimate, which is considered more accurate.

Why is My Due Date Important? 

Healthcare providers use your due date to determine how far along you are during each visit. This information helps guide critical decisions, such as timing specific tests for you and your baby and assessing whether labor is occurring too early or too late.
