About This Tool

Look, I get it—tracking hours isn’t exactly exciting. But if you’ve ever tried to figure out how long you worked last week by squinting at sticky notes and half-remembered lunch breaks, you know it can get messy. That’s where a simple hours calculator comes in. No fluff, no fancy dashboards—just a straightforward way to add up your time, whether you’re freelancing, managing a team, or just trying to stay on top of your own schedule. This isn’t some over-engineered app that tries to do 17 things at once. It’s more like a digital timesheet that actually makes sense. You punch in your start and end times, maybe subtract a lunch break, and boom—you’ve got your total hours. Some versions even handle overtime, multiple shifts, or rounding rules if your company’s into that. At the end of the day, it’s about saving your brain for the actual work, not the math behind it.

Key Features

  • Simple time entry – Just type in your start and end times. No dropdowns, no confusing menus.
  • Automatic calculation – It does the math so you don’t have to. Even handles overnight shifts.
  • Lunch and break deductions – Subtract 30 minutes, 1 hour, or whatever your break actually was.
  • Overtime tracking – Set a threshold (like 8 hours), and it’ll flag anything over that.
  • Export or print – Save your hours as a PDF or CSV, or just print them out for your boss.
  • Mobile-friendly – Works on your phone, so you can log time between meetings or on the go.
  • No account needed – Most basic versions don’t require sign-ups. Just open and use.

FAQ

Can I use this for multiple days at once?
Yeah, most decent hours calculators let you add entries day by day. Some even let you copy a shift across a week if your schedule’s consistent. Just watch out—don’t accidentally double-count a lunch break if you’re copying entries.

What if I work past midnight?
Good question. A solid calculator will recognize that 10 PM to 2 AM is still 4 hours, even though it crosses days. Just make sure the tool you’re using supports overnight shifts—some free ones don’t, and you’ll end up with a negative number. Not helpful.
