Total work time: 7:30 (7.5 hours).
How it works
Use Work hours to add or subtract shift lengths (e.g. morning block + afternoon block, or total hours minus unpaid break). Durations convert to seconds, then sum with +/−. Decimal hours = total seconds ÷ 3600.
Use Timesheet for start/end clock times across days. Rows that cross midnight (e.g. 22:00–06:00) count as overnight shifts. Optional hourly rate estimates pre-tax pay.
Example: 4:00 + 4:00 − 0:30 break = 7:30 worked (7.5 hours).
