Hi,
I've been setting up some multiple events which repeat weekly at the same time and day. What seems to be happening is it's taking every instance of that time and day from the 1/1/1970 rather than using the start date as it's first cut off. You can see what I mean here: http://nbgardens.co.nz/rag-rugging-workshop/
I'd really like to get this fixed asap as the calendar module is pretty central to this website.
