About this calculator
Totaling a week's worth of shift entries by hand, especially with different start times, end times and breaks each day, then working out whether any of that spills into overtime, is exactly the kind of repetitive multi-step arithmetic where a mistake on one day throws off the whole week. This calculator takes each day's shift as a start-end time range, sums the net hours worked across all seven days, and applies a 40-hour weekly overtime threshold to the total (not to any single day), splitting the result into regular and overtime hours. It's aimed at hourly employees and small business owners reconciling a weekly timesheet, where getting the regular/overtime split right directly affects a paycheck.
Worked example
5 days × 8 hours
Result: 40 hours, 0 overtime
