15 PREGNANCY DUE DATE CALCULATORS

When one due date calculator isn’t enough…

pregnancy due date calendar, pregnancy due date calculators, due date, estimated EDD

If you are pregnant and searching for a due date calculator you probably only need to check one or two and get confirmation from your doctor. 

 

I created this list of 15 due date calculators to test out the calculators for the post plotting your due date. Each of the calculators below gave me the same due date when I provided the same information.  

 

Why did I go through this exercise?

 

In the post ‘Plot Your Pregnancy‘, I write about ovulation and the calculations used to determine your estimated due date (among other things) and I wanted to check for consistency. 

 

You can find the list below.

 

The calculators are all pretty basic but the first 2 are my faves because they provide more information. All others are in no specific order.

CHECK WITH YOU MEDICAL PROVIDER

Although each of the calculators easily spits out a number, be sure to check with your prenatal care team for confirmation. 

 

Measurements provided using gestational age (GA) can be more informative than measurements using last menstrual period (LMP).

 

Also, did you know you can estimate your due date without these calculators?

 

1. Use Nagele’s Rule (It’s the same rule the calculators use): 

 

Calculation: [ (The first day of  LMP – 3 calendar months) + (1 year &  7 days) ]

*This calculation is based on a 28 menstrual cycle.

 

If math isn’t your thing, you still don’t need a calculator.

 

2. Our favorite smart people at John Hopkins put together a chart that can give you the results of the calculators. Find it here.
