I am using a jQuery calendar to display events, which is designed to pull data from the server. On innit the calendar fires off a AJAX request to get an array of events objects
You shouldn't be JSON encoding the dates with stringify because the default model binder doesn't expect JSON. Try this:
stringify
$.post('/planner/GetPlannerEvents', { start: start.toUTCString(), end: end.toUTCString() }, function (result) { callback(result); });
