About this calculator
An hours calculator turns a start and end time into total hours worked, subtracting any unpaid break and splitting the result into regular and overtime hours once you pass a daily threshold. Times use 24-hour HH:MM format and an end time before the start is treated as an overnight shift.
Frequently asked questions
How is the break handled?
The unpaid break in minutes is subtracted from the worked span before the hours are reported. A 09:00–17:30 shift with a 30-minute break is 8.0 paid hours.
How are overtime hours split out?
Any hours above the daily overtime threshold are moved from regular to overtime. With an 8-hour threshold, a 9.5-hour day is 8 regular plus 1.5 overtime. Set the threshold to 0 to count everything as regular.
