About Time Period Setup
In Cisco Unified Communications Manager Administration, use the menu path to configure time periods.
A time period comprises a time range that is defined by a start time and end time. Time periods also specify a repetition interval either as days of the week or a specified date on the yearly calendar. You define time periods and then associate the time periods with time schedules. A particular time period can be associated with multiple time schedules.
You then associate time schedules with partitions to set up time-of-day call routing.
