nextDayThreshold
How far an event must run into the next day before it renders on that day. It applies when an event’s end time spans into another day.
Duration, default: "09:00:00" (9am)
Only affects timed events that appear on whole-days: in month view, basicDay, basicWeek, list views, and Scheduler timeline views with day-sized slots. It does not affect all-day events, or timed events displayed against a time-of-day axis, such as in the agenda views.
For example, with nextDayThreshold being the default of 9am, the following event would appear to take up only one day:
{ start: '2014-02-04T20:00:00', end: '2014-02-05T02:00:00' }
// goes from 8pm to 2am the next day
Whereas the following event would appear to take up two days:
{ start: '2014-02-04T20:00:00', end: '2014-02-05T10:00:00' }
// goes from 8pm to 10am the next day
