Calculations with times

The calculation with times and durations has never been easier. Time.Calc can quickly calculate the time difference between two times and supports hours, minutes and seconds.
App for calculating working hours

Calculate working hours

There is a separate mode explicitly intended for the calculation of working hours. You just have to enter the starting time and end of work and include your breaks – that's it! This function is ideal for all employees, working students and freelancers who want to calculate their daily working time without a time recording system.
Calculate AM/PM

Convert 24 hour time to AM/PM

Our app can be used for the conversion of the 24 hour time format to the 12 hour time format (AM/PM). Its flexible configuration allows you to get results in either decimal format (0.5 h) or time format (0:30). You can also tell the app how the results should be rounded, e.g. with quarter-hour accuracy. Last but not least, the app has a dark mode.
Add or subtract times

Easily add and subtract time durations

Time.Calc helps you to add or subtract hours, minutes and seconds. Of course, you can also carry out combined calculations with different time formats, e.g. time (o'clock) or durations (hh:mm:ss)!

Keep track of your calculations

You can easily send your calculations by email or save them in the calendar. If you use the app on your iPad, you will also see a detailed log of the calculations.

I have a very flexible work schedules but am not allowed overtime. I’ve been having a “hard time” clocking out at precisely the right time. My supervisor mentioned it to me several times much to my embarrassment. I spent a good hour looking for solutions (I refuse to do my own calculations when I know there’s a better way) until I found this. Now no matter when I clock in or how long I take for lunch I’ll know precisely when to clock out to get my 8.
Couldn't be without it!

I work for a small business that uses time sheets instead of computers to log employee time. This app completely takes the guesswork and estimations out of calculating my working time. I also love the calculator!
Perfect

Perfect supplement for pro timekeeping with other billing apps as an IT consultant – when there are client limits on hours per week, quickly calculate when to clock out.
Fabulous!!!⭐️⭐️⭐️⭐️⭐️
