Can I set up holiday or seasonal music rotations that automatically activate on specific dates?

Yes, you can set up holiday or seasonal music rotations using clocks and the clock schedule feature. Create separate track groups for your seasonal music (e.g. "Christmas Songs", "Halloween Music") and build special clocks that include these seasonal track groups alongside your regular programming elements.

To schedule these automatically, go to Manage > Clock Schedule and, in the Clock Grids view, create a new clock grid for your seasonal programming on a higher Layer than your standard week grid. Fill in only the hours you want the seasonal clocks to play, then click Edit Date Ranges... and add a date range such as 1 December to 31 December, ticking Ignore year on dates so it repeats every year. Outside that range the seasonal grid is ignored and your normal schedule plays, so your seasonal programming activates on the same dates each year without manual intervention. Using more than one clock grid requires the Advanced Scheduling module.
