## Using the Years Between Calculator

To compute the distance in years between two dates, fill out the top two inputs:

**First date:**Enter the start date for the math**Second date:**Enter the end date for the calculation

Next, hit the blue 'Calculate Years Difference' button. You'll quickly receive one result:

**Time Between:**The difference between the two dates including both the year difference and the number of remainder days

### How does the tool add up the days?

The year calculator starts by counting the entire first day, but **doesn't count the ending date**.

*Try it:* enter the day and the next date and you'll get '1', not '2' or '0' days in between.

### Does the year calculator include leap years?

Yes, it sure does. Years are abstractions though, so unless you try to deliberately bracket February 29 in a leap year you might not even know a leap year is in the calculation.

However, leap years are in the tool. If you see a day difference that looks "off by one", it's actually correct and you're seeing the extra leap year day counted.

### Does the first date have to come before the second?

Nope. Set them in either order you'd like, or even set them to the same date – the tool will figure it out.
