Three calculators
Add up durations: type one duration per line (1:30, 1h 30m, 90m, 1.5h) and see the total as hours and minutes, as 1:30 style, as decimal hours and as minutes. Fill in “Subtract” to take a break off the total.
Between two times: the first box gives the length from one clock time to another; if the end is earlier than the start it counts through midnight, so 22:00 to 06:00 is 8 hours. The second box starts from a time and adds or subtracts a duration, for example 9:00 plus 2h 30m is 11:30 AM.
Weekly timesheet: enter the start and end time and the length of the unpaid break for each day. Each row shows the time worked and the week total in hours and minutes and as decimal hours, which is the form most payroll systems ask for (7h 30m is 7.5 hours).
Questions
How do I write times? 9, 9:00, 9:00 am, 5pm and 17:30 all work. Does it round? Minutes are exact; decimal hours are rounded to two places. Is my timesheet stored? Only in this browser, so you can fill it in over the week. Nothing is uploaded. Use the Age & Date Calculator for days between dates and the Salary Converter to turn hours into pay.
