How to Use the 24 Hour Timesheet Calculator
Using the calculator is very simple. You only need three inputs:
Step-by-Step Guide:
1. Enter Start Time
Select the time you started working in 24-hour format (e.g., 09:00 or 22:30).
2. Enter End Time
Enter the time you finished working. The tool also supports overnight shifts automatically.

Formula Used in Timesheet Calculation
The calculator uses time difference and subtraction formulas to calculate results.
1. Total Time Worked
Total Time = End Time − Start Time
If the shift crosses midnight:
End Time = End Time + 24 hours adjustment
2. Convert Time to Minutes
Total Minutes = Total Hours × 60 + Remaining Minutes
3. Net Working Time
Net Time = Total Minutes − Break Time
4. Final Output Conversion
Hours = Net Minutes ÷ 60
Minutes = Net Minutes % 60
