What this leaves out or assumes
- Breaks are taken off as unpaid. A finish time earlier than the start is counted as the next morning, for night shifts.
Where the figures come from
This sum uses only the numbers you entered.
How hours are added up
For each day the calculator takes the finish time away from the start time, then takes off your unpaid break. A finish time earlier than the start, such as 22:00 to 06:00, is counted as finishing the next morning, so night shifts work too.
The total is shown two ways. Hours and minutes, such as 37:30, is how a clock shows it. Decimal hours, such as 37.5, is how most payroll and timesheet systems want it, because you can multiply it by an hourly rate. 30 minutes is 0.5 of an hour, 15 minutes is 0.25 and 45 minutes is 0.75. The hours to decimal converter has every minute.
Breaks and working time
Adult workers have the right to a 20-minute rest break if they work more than 6 hours a day. Whether a break is paid depends on your contract. Most workers cannot be made to work more than 48 hours a week on average. GOV.UK explains rest breaks and maximum working hours.
