Work Calendar Exceptions

A work calendar exception is a way to mark out a chunk of time as an exception to what is defined as the rule. You can create Working exceptions or Non working exceptions. These can be defined for a Work Calendar or for a User. 

• For example, a user is on vacation for 2 days (Monday/Tuesday). Assume that their regular work calendar considers Mon/Tue as Working. So you have to create an Exception for that user and mark their Mon/Tue as Non-Working.
• You may also use an Exception to mark a Non-Working day as Working. e.g. according to the Work Calendar a user is off on Saturday and Sunday. But you want them to work on a Saturday. To do this you would create an Exception for that day for that user and mark it as Working. 
• Similarly, 25th Dec which say happens to fall on a Monday is to be flagged as a Company Holiday. So you have to define a "work calendar exception" to mark this day as a "non-working" day for the Work Calendars applicable.
