Its been a while since I made a STAR app to cover a multi-day holiday [for a client], but I could have sworn that a STAR was able to span past midnight. In other words, the start day used the start time and the stop day used the stop time.

Apparently not. It seems I have to make 2 entries for each holiday to cover an extended period of time. Did Mitel change this at some point in a recent version?? My client is using v5.0.4.63
