Replace All Entries in Custom Timeframe

If a new array of entries is supplied in the update request for a Custom timeframe, it will replace all existing entries in the timeframe, meaning that any existing entries in that timeframe will be removed. To update individual entries within a Custom timeframe, refer to "Update Entries within Custom Timeframe." It is not necessary to supply a timeframe-id for the new holidays. These timeframe-ids will be generated automatically.
