Add up a week's worked hours from daily clock-in and clock-out times, minus breaks.
A week's hours, totalled
A timesheet means adding up each day's worked hours — clock-in to clock-out, minus unpaid breaks — across the week, which is fiddly because time runs in sixties and breaks complicate every day. This totals a week of daily times into worked hours, so payroll or invoicing is based on an accurate figure rather than hand-counted arithmetic.
Enter each day's times and breaks to see the weekly total.
Where hand-counting goes wrong
Timesheet errors are common and always the same kind: miscounting because sixty minutes is an hour not a hundred, forgetting to subtract a lunch break, or fumbling a shift that crosses midnight. Each small slip, repeated across a week and a month, adds up to real money for someone. For payroll the result often needs converting to decimal hours to multiply against a rate, which is the natural next step from an accurate hours total.
Frequently asked questions
Does it subtract breaks?
Yes — you enter each day's unpaid break, and it deducts them to give the actual worked hours.
Why are timesheets so error-prone by hand?
Because time runs in sixties not tens, breaks must be subtracted, and shifts can cross midnight — each an easy slip that adds up over a month.
