Make the day change explicit
A shift from 22:00 to 06:00 crosses midnight. Count 2 hours before midnight and 6 hours after it: 8 hours in total. With a 30-minute unpaid break, the worked time is 7 hours 30 minutes.
In the timecard tool, select Next day. Without that choice, an end earlier than the start is an error, not an automatic assumption.
An overnight example with an unpaid lunch break
Start at 22:15 and finish at 06:45 the following morning. There are 1 hour 45 minutes before midnight and 6 hours 45 minutes after it: 8 hours 30 minutes on site. Subtract a 45-minute unpaid break to get 7 hours 45 minutes, or 7.75 decimal hours.
Enter 22:15, 06:45, Next day and 45 break minutes in one timecard shift. If you instead enter the periods before and after the break as separate shifts, do not subtract that same gap again.
Check equal start and end times
06:00 to 06:00 means zero clock hours on the same day, but 24 hours when Next day is selected. Check the actual dates before making that choice. A single timecard entry is limited to 24 hours; record a longer period in separate entries.
If you know the start time and need to plan the finish, add the target working hours and unpaid break minutes. For example, 22:00 plus 8 hours of work and a 30-minute unpaid break finishes at 06:30 the next day. The clock-out calculator handles this planning task.
Check clock changes and week boundaries
An overnight shift during a daylight-saving clock change may have a different elapsed duration from its clock-time difference. These tools use entered clock times and do not make a timezone correction.
Timecard hours are assigned to the shift’s starting day. If your payroll rule splits hours at a weekly boundary, split that shift into the corresponding separate entries.
For example, a Sunday 22:00–Monday 06:00 shift can be recorded as Sunday 22:00–00:00 with Next day selected, then Monday 00:00–06:00. Assign any unpaid break to the period in which it occurred and subtract it only once. Choose the actual workweek boundary required for your record.
Calculate your shift
Use the timecard calculator with unpaid breaks and overnight shifts to add a week or two weeks of completed shifts. If you know your start time and the work hours you need to complete, use the clock-out calculator with a lunch break to find your finishing time.
