I like the idea as well
FWIW, along with date-specific timers, I have two timers built in my CM15 for Christmas lights that actually have no date range. They are HC/UC that I do not normally use on a daily basis. While I 'could' make them date range specific, I do not because it allows me to have 'baked in' timers for outside (or inside) lighting that I need on a temporary basis throughout the year, be it for working on something or a party, etc, etc. They run every day, but with no modules set up, they just evaporate...
