What Is a Date Difference Calculator?
A date difference calculator computes exactly how much time separates two dates — in total days, weeks, and approximate months and years — so you don't need to count on a calendar or account for varying month lengths and leap years by hand.
It's useful for anything from calculating a project deadline's remaining runway to figuring out how many days until (or since) a significant event.

Use Total Days for Precise Calculations
The "total days" figure is exact; months and years are approximate averages.
Order Doesn't Matter
You can enter the later date as the "start" date — the tool reports the absolute difference either way.
