@wgtn28: Odd-day restriction skipping 31st and Feb 29th is a pretty standard practice — most sprinkler controllers that support odd day restriction do the same. The reason is that the day following the 31st (as well as Feb 29th) is another odd day, so this avoids watering two days in a roll.
Program not executing on Jan 29th is unusual. To make sure there is no other factor: are you using weather-based water time adjustment? Did you set your program to run on specific days of a week? I didn’t quite understand what you said here: “Odd programs set to run on the 29th day appear in the UI “Program Preview” page in advance before and after the 29th date, but once the current date is the 29th changes to “No stations set to run on this day.” and no watering is activated.”. Do you mean the Program Preview shows “No stations set to run on this day” or do you mean the Log shows “No stations ran on this day”? If the preview shows no stations set to run on this day, it would be either the weather-based adjustment set it to zero, or your programs are set to run only selected days of a week. Hope this makes sense.
