Multuiple bugs in calendar

Expected behavior Events appearing in the Month view should appear consistently in the week and day views.

Actual behavior

Events appear correctly in the month view and the list view, but are screwed up in the Week view, and missing in the Day view (an error gets thrown in the Day view)

Resources (screenshots, code snippets etc.)

I'm using things in the most trivial way out-of-the-box. The script I'm using to render the calendar is shown below (and supplied in the above-mentioned archive). If you run this (and get the same experience I'm getting, of course), then on the Month view for the week of May-10 -... May 16 you should see an entry of 2:30pm on Monday, Wednesday and Friday called "Latin", and 9:45am on Tuesday and Thursday for "Ancient Greek", and 4:40pm on Friday for Physics. This is fine on the Month view. On the Week view I'm only seeing Latin on Monday (not Wednesday or Friday), and only seeing Ancient Greek on Tuesday (not Thursday), and the Friday event for Physics has landed on top of the Tuesday event for Ancient Greek at completely the wrong time of day.

On the Day view, it throws an error (see also screen shot in zip archive):

TypeError: s is undefined fullcalendar.min.js:formatted:2868 renderFgSegEls fullcalendar.min.js:2868 jQuery 2 renderFgSegEls fullcalendar.min.js:2864 renderFgRanges fullcalendar.min.js:2806 render fullcalendar.min.js:2797 executeEventRender fullcalendar.min.js:5589 executeEventRender fullcalendar.min.js:7198 requestEventsRender fullcalendar.min.js:2422 runTask fullcalendar.min.js:5471 runRemaining fullcalendar.min.js:5403 tryStart fullcalendar.min.js:5393 resume fullcalendar.min.js:5387 stopBatchRender fullcalendar.min.js:2311 renderView fullcalendar.min.js:6071 changeView fullcalendar.min.js:5931 g fullcalendar.min.js:7851 w fullcalendar.min.js:7859 jQuery 2

and only shows the time range from midnight to 4pm. If i click away from the Day view and come back, the error persists, and now the page doesn't show any times at all. The List view works just fine.
