Resource Usage Reports use a combination of the working week defined in the site regional settings; information entered into the Project Calendar (if active); and Working hours per day specified on the BrightWork Settings page to assist in the performance of their calculations.
There are two types of exception days:
(1) Working Time
(2) Non-Working Time
Example exception days include a working day that is a holiday (e.g. public holidays) or a non-working day that is actually working day (e.g. a weekend day).
