A Days of Week timeframe consists of a single Days of Week entry within the timeframe-day-of-week-array array inside the timeframe. In order to create a Days of Week timeframe, supply a single new Days of Week entry object within the timeframe-day-of-week-array array in the create request. See examples for more information.
When creating a Days of Week timeframe it is not necessary to supply a timeframe-id for the timeframe or for the Days of Week entry within that timeframe. These timeframe-ids will be generated automatically.
