Method, examples and limits
09:00-12:30 and 13:30-18:00 give 8:00. An additional 30-minute break gives 7:30. Enable overnight intervals for 22:00-06:00 to get 8:00. Overlapping intervals and breaks longer than working time are rejected. The model represents one 24-hour cycle, uses wall-clock times and excludes daylight-saving changes, wages and overtime premiums.
Frequently asked questions
Should I add the break between two intervals?
No. Time not entered is already excluded. The breaks field is only for further minutes to subtract.
