How it’s calculated
End time − start time − unpaid breaks. Paid breaks stay in worked time.
9:00 AM–5:00 PM, with a 30-minute unpaid break, is 7 hours 30 minutes.
For overnight work, select “Ends the next day.” This tool uses clock times, not dated timestamps; it does not adjust for daylight-saving changes, shifts longer than 24 hours, or overtime. Use the app to keep dated shift records.
