About This Tool

So, you need to figure out how many days are between two dates? Yeah, I’ve been there. Maybe you're planning a trip, tracking a project deadline, or just curious how long it’s been since that weird thing happened last summer. Whatever the reason, a days calculator is one of those simple tools that somehow makes life a little easier. It’s not fancy. No animations, no pop-ups, no “premium upgrade” nonsense. Just pick a start date, pick an end date, and boom—you get the number of days in between. Clean. Fast. Honest. I built this because I kept opening a spreadsheet every time I needed to do this. Enough was enough. Now it’s here, free to use, and doesn’t ask for your email or try to sell you anything.

Key Features

  • Calculates the exact number of days between any two dates
  • Works forward or backward—so you can see how many days until something or how long it’s been since
  • Includes weekends and holidays in the count (because, let’s be real, time doesn’t stop for weekends)
  • No login required—just open and use
  • Mobile-friendly, so it works on your phone without acting weird
  • No ads cluttering up the screen while you’re trying to focus

FAQ

Does it count the start and end dates?
Yes. If you pick the same date for both, it’ll show 1 day. If you want to exclude one, just subtract 1 manually. I kept it simple—most people expect both days to count.

What if I need business days only?
This version doesn’t filter out weekends or holidays. I might add that later, but for now, it’s all days. If you need business days, you’ll have to do a little math or use a different tool. Sorry—no magic wand here.
