How to use our Time Duration Calculator

Using our time duration calculator is a breeze. Just pop in your start and end times, and voilà – you'll get the duration in both decimal hours and in hours and minutes. For instance, if you start at 8:30 AM and wrap up at 4:15 PM, it'll show as 7 hours and 45 minutes, or a neat 7.75 hours.

We give you decimal hours because it's a snap for payroll calculations. But don't worry, we haven't forgotten the classic hours and minutes format – it's great for when you're chatting or jotting down notes. And if you've already got a duration and just need it in decimals, our decimal hours calculator is here to save the day.
