Choose the date and time you want to leave, how long you need to work and any unpaid break. We’ll work backward to find your exact clock-in date and time.
Leave at 5:30 PM after 8h 00m of paid work and a 30-minute unpaid break.
Start with your desired clock-out date and time, then subtract your paid work duration and every unpaid break.
The selected date removes the guesswork for overnight shifts: the result shows the actual earlier calendar date. Paid rest breaks are already inside paid work time, so do not subtract them again.
For 8 paid work hours and a 30-minute unpaid lunch, clock in at 9:00 AM. If the lunch is paid, clock in at 9:30 AM.
Yes. To keep the same clock-out time, subtract the unpaid lunch as well as the paid work duration. Paid breaks should not be entered as unpaid time.
Yes. Enter 7 in the hours field and 45 in the minutes field. The result updates immediately.
Yes. The chosen clock-out date lets the calculator show the real earlier start date. For example, leaving at 6:00 AM after 8 paid hours and a 30-minute unpaid break means clocking in at 9:30 PM on the previous calendar day.
Yes. Add to calendar downloads an ICS file with the calculated start and end dates and times. The file uses the local time shown on this device and can be imported into most calendar apps.
This planner subtracts the entered duration as elapsed time using your device’s local time zone. Calendar clocks can jump forward or backward on a daylight-saving transition, so verify unusual overnight results against your official schedule.
Your latest duration and break settings are saved only in your browser on this device. The selected date is not retained unless it is included in a share link. Nothing is uploaded by this calculator, and no account is required.
