What Is a Hours Calculator?
A hours calculator computes the total time worked between a start time and end time, optionally subtracting a break. You can add multiple time entries (e.g. different days or shifts) and get the total hours in both hours:minutes and decimal format. Useful for timesheets, freelance billing, and payroll.
How to Use
- Enter start and end times in HH:MM format (24-hour or 12-hour both work)
- Optionally enter a break duration in minutes
- Add more rows for multiple shifts or days
- Total hours and decimal equivalent are shown at the bottom
Features
- Supports overnight shifts (e.g. 22:00 to 06:00)
- Break time subtracted per entry
- Multiple entries for weekly timesheet totals
- Decimal hours for billing (e.g. 7.5 hours)
FAQ
How do I enter times?
Use HH:MM format, e.g. 09:00 for 9am, 17:30 for 5:30pm, 22:00 for 10pm. Overnight shifts are handled automatically — if end time is earlier than start time, the calculator assumes the shift crossed midnight.
What is decimal hours?
Decimal hours express time as a fraction of an hour. For example, 7 hours 30 minutes = 7.50 decimal hours. This format is commonly used for billing and payroll calculations.
Can I calculate a full week?
Yes. Add one row per day (Monday through Friday, for example) and the total at the bottom will sum all entries.
