How to Use the Work Time Calculator
- Enter Start and End Times – Fill in the Start Time and End Time fields using the 24-hour format (e.g., 09:00 to 18:00). Both are required.
- Add a Break (Optional) – If you took a break, enter the Break Start and Break End times. Leave both empty if no break.
- Click "Calculate" – The button validates your inputs. Ensure the end time is after the start time, and the break (if provided) is within work hours.
- Read the Results – Three values appear:
- Total Hours – Time from start to end.
- Break Hours – Duration of your break.
- Net Work Hours – Total hours minus break (your actual work time).
Tip: All times use the 24-hour clock. Results display in hours and minutes (e.g., 8.30 = 8 hours 30 minutes).
