Hi,
I bump this thread because after reading this post I was excited but after reading here this template is still not available :-/ Of course we still can create from scratch (thanks for Calendario link) with a list and some html/css/js guru but I think we all dream about a calednar template with fields positions, and why not (it's a dream after all ^^) repeating date or multiple days event management and of course in STORE.
Maybe we you can start with tutorial based on Octopoos Event calendar and Calendario ;-) It's still some works and time but a lot less than clean coding and sharing a full template / App
