The Age Calculator

Instructions:

Simply enter your age and check whether not you've celebrated your birthday this year.

In the third box, enter a year you're curious about. Entering a year in the future will tell you how old you will be, while entering a year in the past will tell you how old you were, or how many years it was before you were born.

Check if you've had your birthday this year:

What year do you want to know about?

While I could just ask you to enter the date of your birthday, even though this is all run locally on your browser and I have no way of seeing what you put here, you shouldn't enter your personal information on random websites.
