Hours and Minutes Calculator

Enter the hours and minutes for each time entry into the corresponding fields. The calculator sums all entries, automatically carrying over any minutes that exceed 59 into full hours. For example, 1h 45min + 0h 30min = 2h 15min.

Yes. Enter each work session or task as a separate row with its hours and minutes. The total at the bottom gives you the combined time worked, which you can use directly for payroll reporting or freelance invoicing.

Decimal hours express time as a single decimal number instead of hours and minutes. For example, 1 hour 30 minutes equals 1.5 decimal hours. Many billing systems and payroll platforms require time in this format.

Multiply the total hours by 60 and add the remaining minutes. The calculator does this automatically and shows the result in the 'Total in Minutes Only' field. For example, 2h 15min = 135 minutes.

Enter each task's duration as a separate entry. The running total in the breakdown table shows cumulative time after each task, making it easy to see where time is being spent across a project.

A 12-hour clock divides the day into two 12-hour periods — AM (midnight to noon) and PM (noon to midnight). A 24-hour clock runs from 00:00 to 23:59 without AM/PM labels. This calculator works with durations (elapsed time), so AM/PM does not apply here.

Some employers round clock-in and clock-out times to the nearest 5, 6, or 15 minutes before totalling hours. This calculator uses exact minutes as entered, so apply any rounding to your individual entries before inputting them if your employer requires it.

This tool adds multiple time durations together. To find the difference between two durations, enter the larger value in Entry 1 and the smaller value in Entry 2, then subtract manually from the total. For start-to-end time differences, a dedicated time-between-hours calculator is recommended.
