offset end date

The dates are interpreted as exact time points, i.e. when the start date is set to 01.01.2014 it means 2014-01-01T00:00:00, the end date 03.01.2014 means 2014-01-03T00:00:00. The difference between these two dates is 48 hours.

If the end date of 03.01.2014 should mean "the end of 03.01.2014" you need to add 1 day to this date when displaying it in DayPilot.

We know we have to add a date, that's obvious, but can you post an answer on how to do this? This is a common issue with your interpretation of date ranges. When you schedule someone by days, not hours, from Dec 1 to Dec 3 they are schedules for 3 days. This should be the default behavior and should allow overrides, not your 2 day interpretation by hours.
