For night shifts workers many calendars (including KOrganizer and Merkuro) are not really usable.
The month view is the most convenient way to check a schedule, but when events span across two days, they appear on both days.
For night schedules, when multiple events overlap, the calendar is a total mess to read.
Google, Proton and some others, apply a different way to show these events.
On the month view, if the duration of the event is less than 24 hours, it only appears on the first day, making the month schedule very easy to read when there is multiple events on consecutive days.
IDK if it may be an option for KOrganizer?
