How the pregnancy due date calendar works

You've probably heard of a pregnancy due date calculator, but do you know what one is and what it can do for you? Let's start with the basics.

A pregnancy due date calculator is a tool that helps you estimate when your baby will be born. It does this by considering the first day of your last period, the average span of a human pregnancy, and some other factors.

While most calculators are fairly accurate, remember that they are just estimates. We believe that birth is "baby-led," and every pregnancy is different, so your baby may come earlier or later than predicted. With that in mind, let's look at the 5 things you should know about using a pregnancy due date calculator.

How does the due date calculator work

Here are five things to know about how the calculator works:

The calculator considers the average length of pregnancies, which is about 40 weeks.
It estimates your due date by counting back from the first day of your last menstrual period (LMP).
The calculator can be accurate within a week or two.
It's based on averages, so it's not 100% guaranteed to be correct for everyone.
If your baby is premature or overdue, the calculator may not be as accurate.

How much can you rely on the calendar?

No one can predict when you'll go into labor with 100% accuracy, but that doesn't mean your due date calculator can't give you a good estimate. The calculations are based on the average length of pregnancies and the date of your last period.

However, let's emphasize again that these calculations are just estimates. Many things can change the outcome, including your cycle, so don't be too surprised if your baby arrives a little earlier or later than predicted.
