I need a draggable, editable calendar view that does 'days from now' instead of objective dates. Basically I'm going to have a daily cron job check the days since a certain event, find the nodes with a matching integer field and fire a bunch of rules on that node. No actual dates involved.

Fullcalendar is almost perfect, but rather than displaying 30 days in November (for example) and updating the date field when nodes are dragged around, I need to display an arbitrary number of ascending integers in a calendar format and change the integer field when the nodes are rearranged.

So is there already a way to get this module to use integers instead of dates? Have there been any issues dealing with this? Can you give me any pointers if I need to build it myself?

Thanks.
