Add up hours and minutes, one duration per line. Start a line with - to subtract. Nothing leaves your browser.
Each line is converted to minutes, the lines are added (or subtracted if they start with a minus sign) and the total is shown as hours and minutes, total minutes and decimal hours. Totals can go past 24 hours.
Enter each duration on its own line, for example 1:30 and 2:45. The total is 4:15, which is 4 hours 15 minutes.
Use h:mm like 1:30, or words like 2h 15m, 45m or 1 hour 30 min. Start a line with a minus sign to subtract.
Divide the minutes by 60. A total of 1:20 is 1.33 hours. The tool shows this for you, which is handy for timesheets and invoices.
