A scheduling order can be designated for the broadcast and playback of multimedia content (e.g., music, news, other audio, advertising, etc) with respect to slots within the scheduling order. The broadcast day is divided into dayparts having blocks of time and including multiple time slots. One of those time slots, a transition period, is adjacent to another daypart. The transition period may be scheduled using a different algorithm for adjacency scheduling to satisfy both horizontal and vertical adjacency requirements. The remaining slots for the schedule can be scheduled from one or more categories of media items associated with the block being scheduled.
