CalendarsUnless all services of your contact center operate on a 24/7 basis, you will have to define separately what happens to incoming interactions when the corresponding services are open for business and when they are closed. You can define service operation hours when you configure your [[contact-center-administrator-guide/PropertiesTab|services]] or [[contact-center-administrator-guide/Dial-in|scenario entries]]. However, if your contact center has many different services, and some of them operate on the same schedules, it may be more convenient to define such schedules externally first, and then assign them to services and/or scenario entries. In this way, if you need to change a service operation schedule, you do it once, and the change will automatically apply to all services associated with this schedule.Creating an external schedule involves two steps. First, you create calendars (i.e., define the days that are supposed to have the same hours of operation, such as Monday through Friday or public holidays). Calendars are discussed in this section. After that, you create the schedule itself by combining the different calendars and specifying hours of operation for each assigned calendar. Such complete schedules are discussed in section [[contact-center-administrator-guide/HoursofOperation|Hours of Operation]]. Note that the calendars are also used for defining [[contact-center-administrator-guide/Outbound-CallingHours|calling hours]] of outbound campaigns. '''Note:''' The system provides a number of predefined calendars that include a typical work week, weekends, and US holidays. The latter can be used for defining [[contact-center-administrator-guide/StateCallingHours|state calling hours]]. The default holiday information is current as of the release of version 3.6 of the Bright Pattern Contact Center system (June 2014). It is recommended that you periodically check the federal and state legislation regarding holidays, and update the calendars as may be necessary.To work with calendars, select the ''Calendars'' option from the ''Call Center Configuration'' menu.[[File:Calendars-Admin-50.png|thumb|800px|center|Call Center Configuration > Calendars]]The ''Calendars'' screen properties are organized into two tabs: Day types and Associations. The screen properties for both are described as follows.''Name'' refers to the calendar name. This field is mandatory and must be unique within the contact center.These are the ''days'' within this calendar. Note that all days within a calendar are supposed to have the same hours of operation.To remove or edit calendar days, hover the cursor over their names.This option allows you to define a new calendar based on the currently selected one. When you click '''clone''', a copy of the currently selected calendar is created with default name ''Copy of [Calendar Name]''. You can change the calendar name, as well as add days to, or remove them from, or edit them in, this new calendar.''Services'' lists the [[contact-center-administrator-guide/ServicesandCampaignsOverview|services]] that use the given calendar.
