Four computers, four clear tasks

Working time calculator Shift from start to finish minus break

Working days calculator Days between two dates including weekends and public holidays

Working time is not the same as total time

If you want to calculate a shift, you need a start, end and break. On the other hand, if you collect project times or individual blocks, you need a totalizer. That's exactly what separates Working time calculator and Hour calculator.

Industrial minutes: the common pitfall

30 minutes is not 0.30 hours, but 0.50 hundredths of an hour. The Industrial Minutes Calculator is therefore a special tool and not just an optical variant.

Working days: calendar instead of time

At the Working days calculator It's not about hours, but about days in the period, weekly model and holidays by federal state.

Conclusion

Time calculators have a similar effect, but solve different tasks. Clean separation saves errors and improves search intent.
