Work Hours & Timesheet Calculator guide

Use and export

Enter each shift-start date, clock times, unpaid break and overnight flag.

Choose overtime, week start, rounding and optional pay assumptions; calculate.

Review weekly totals and export the timesheet, report or editable JSON draft.

Methods and limits

Up to 366 entries. Clock spans are checked for overlap; an overnight shift must be explicitly marked and may span up to 24 hours. Unpaid breaks are subtracted before optional nearest-duration rounding. The shift-start date determines payroll day and week; overnight entries are not split at midnight. Daily/weekly thresholds are user assumptions, with overtime assigned once. Weekly regular capacity excludes daily overtime. Pay uses exact currency minor units and a chosen overtime multiplier, rounded per entry. These are estimates, not payroll-law compliance. The tool calculates clock durations without DST adjustment.
