I need to have a calendar with two 12hour shifts per day.
I did create a new working calendar and set starting time to 0:00 and end to 24:00 (which is automatically changed to 0:00)
but when I enter a task with 12 hours the task will still span multiple days?
How should I set up the calendar correctly?
Use "options" on the calendar mask. Set working hours per day, per week, days per month.
