About Hours Calculator
Helps you check your workday: hours worked, overtime and the monthly balance, with breaks deducted.
A practical example
You start at 8:00, leave for lunch at 12:00, come back at 13:00 and finish at 17:30. With the 1-hour break deducted, the day adds up to 8h30. If your target is 8 hours, the balance is +0h30. At the end of the month the calculator adds up the balance of every day and shows whether you have overtime or hours to make up.
How to use it
- Enter the start, end and break times for each day.
- See the total worked and the balance against your daily target.
- Follow the history month by month.
- Export to CSV for spreadsheets or for your employer or clients.
Limits and cautions
- Records are saved only in this browser; clearing the site data erases the history.
- It is a support calculator, not a replacement for your employer’s official time clock.

What happens in your browser
Each day is calculated as the difference between the end and the start time, minus the breaks you entered. The balance compares the result with the daily target you set, and the monthly totals are the sum of the days.
Records are kept in the browser’s local storage, on this device. There is no account and no server, so they do not sync between devices and can be erased if you clear the site data.
The CSV export opens in spreadsheets such as Excel and Google Sheets, so you can keep a copy or send it to your employer or a client.
