If there's an appointment, for example, that's 1st Jan 00:00am- 2nd Jan 00:00am, then the calendar will show it on three days - 31st, 1st and 2nd.
Is it possible to stop it from appearing on the days where it only starts or ends?
So, an appointment would not appear on a day when it starts at 00:00pm and when it ends at 00:00am. If an appointment started and finished at 00:00am and 00:00pm, then it could default to appearing on the day it starts.
