About this time difference calculator

This tool calculates the difference between two times and shows the result as a duration (hours, minutes, and seconds), plus decimal hours for payroll and timesheets. In clock mode, it can automatically handle midnight crossings (for example, 22:30 to 06:15). You can also subtract break time to get your net working time. In date & time mode, you can calculate exact differences across multiple days. Everything runs locally in your browser and your last settings are saved for quick reuse.
