A work calendar defines the working and nonworking times for an organization. It specifies the work hours for each work day, the work days for each week, and any exceptions, such as holidays.
You can define many work calendars each with its own time-zone, working hours and exceptions.
Work calendars are used in scheduling tasks.
Using Work Calendars
Every user must belong to one and only one work calendar. Work calendar can be set for a user from the add/edit user screen or from the bulk edit screen.
Every project has a default work calendar. All dates on its interactive Gantt chart are shown with respect to this work calendar's time-zone. The default work Calendar can be set for a project from its add/edit screen.
Managing Work Calendars
Only administrators can manage work calendars. To manage work calendars, navigate to Top Menu ▸ ▸ Admin ▸ Project Management ▸ Work Calendars
Exceptions (Holidays, Vacations, etc.)
Exceptions are times that are an aberration to the rules defined in the work calendar. Exceptions can be defined for the entire organization (e.g. Christmas holiday), for work calendars (e.g. 4th July holiday only in the U.S.) or for individuals (e.g. Joe is going on a vacation from 3rd to 10th May 2016).
When exceptions are added, modified or deleted, task dates are recalculated. For example, if Mark is sick on a 3rd May and a work exception is entered, all tasks that Mark was supposed to work on 3rd May will be pushed a day ahead.
Working and Non-Working Exceptions
While most exceptions are non-working, you can also enter working exceptions. For example, if Peter is going to work on a Saturday, the 10th of June, you can enter a working exception for Peter on 10th June and all tasks assigned to Peter will be rescheduled appropriately.
Only administrators can add organization wide or work calendar exceptions. To manage exceptions, go to Top Menu ▸ ▸ Admin ▸ Project Management ▸ Work Calendars and click on the Exceptions tab.
