About Hours Calculator
Add Up Your Work Hours
This hours calculator lets you enter multiple start and end times to find the total hours worked. Each row can include an optional break deduction, so your totals reflect actual working time.
How It Works
Add a row for each time block - a shift, meeting, or task. The calculator computes the duration for each entry and sums them into a grand total shown in hours and minutes, total minutes, and decimal hours. Decimal hours (like 7.50 instead of 7h 30m) are useful for timesheets and payroll. Overnight shifts are handled automatically when the end time is before the start time.
Optional Pay Calculation
Enter an hourly rate and select your currency to see your total earnings. The calculator supports 8 currencies including USD, GBP, EUR, and JPY. For a more detailed salary breakdown, try the salary calculator. To find the number of working days in a period, use the work days calculator.
All calculations run in your browser. No data is collected or stored on any server.
Frequently Asked Questions
How do I calculate hours worked across multiple shifts?
Add a row for each shift using the "Add Row" button. Enter the start time and end time for each entry, and optionally deduct break minutes. The calculator totals everything automatically.
Does it handle overnight shifts?
Yes. If the end time is earlier than the start time, the calculator assumes the shift crosses midnight and calculates accordingly.
What are decimal hours?
Decimal hours express time as a decimal number instead of hours and minutes. For example, 7 hours 30 minutes is 7.50 decimal hours. This format is commonly used on timesheets and payroll systems.
Can I calculate my pay?
Yes. Enter your hourly rate in the optional pay calculator section and choose your currency. The tool multiplies your total decimal hours by the rate to show your total earnings.
Is my data stored?
No. The hours calculator does not save data between sessions. All calculations happen in your browser and nothing is sent to a server.
