Yes, but we recommend the timers don’t overlap. For example: create a calendar event for Tennessee Walking Horse Celebration week (Shelbyville, late August) running 7pm–11pm, then a daily warm-white timer from 11:01pm–5am for the routine glow. Same logic applies to Dickens of a Christmas weekend in downtown Franklin, Pumpkinfest, the Brentwood Tree Lighting, Mule Day in Columbia, or the RC-MoonPie Festival in Bell Buckle — calendar events override daily timers for those windows, then the timer resumes.
