About the Hours Calculator
The Hours Calculator computes the span between a start and end time, subtracts breaks, and shows the result as h:mm and as decimal hours (the format payroll systems want). Overnight shifts are handled automatically: an end time before the start counts into the next day — built for Früh-, Spät- und Nachtschicht alike.
7:45 = 7.75 h — minutes ÷ 60. Timesheets and payroll multiply decimal hours by the hourly rate.
If the end time is earlier than the start, the tool assumes the shift crosses midnight and adds 24 hours.
