About the Age Difference Calculator

With this calculator, you can easily find out the exact age difference between you and others, from your kids and partner to other family members, and friends too.

Currently pregnant? Use your EDD to get an EAD (estimated age difference)! Then, when your baby is born, you can calculate the exact age difference - which is a pretty cool piece of info to know, since any actual age difference will be a constant in your life. For example, if the age difference between you and your baby is 29 years 10 months and 16 days, as you both grow older, your age difference will always be 29y10m16d!

And, of course, you can also age yourself with your favorite celebrities. Below are several celebrity and well known couples, many having age gaps of 10 to over 20 years. Just click/tap on the couples' name, and then tap the Calculate button to instantly see their age difference and current age!
