Pregnancy Due Date Calculator - Learn Your Estimated Due Date

Pregnancy Due Date Calculator

Are you looking to see what you're due date might be?  If you know some information, you are able to get an estimated due date with our pregnancy due date calculator.  Keep in mind, the pregnancy due date calculator is only an estimate date. The pregnancy due date calculator will calculate your estimated due date, the fetal age, which is the age of your developing baby and the conception date.

How does the Pregnancy Due Date Calculator work?

Ever wanted to know how your doctor or health care provider calculates your estimated due date? Well, it is actually a really simple process:

You add 280 days to the first day of your last menstrual period, or LMP.

It is really as simple as that. The 280-day cycle works on the typical 266-day gestation period for humans. We get 280 days because we add 14 days, which is the average time span for when you would have ovulated. Obviously this is just and average, but the 14 days can be changed for what ever your Luteal Phase actually is in the calculator below.

The more you know about your monthly cycle the more accurate our pregnancy due date calculator will be. Of course not all pregnancies are planned, but if your monthly cycle is more regular, then you should have no problems using the pregnancy due date calculator.
