Clicking this menu item leads to a calendar. Days that are painted yellow already have special timeslots assigned.
Selecting a day, the user gets a timeslot overview for that day. The timeslots for this day can now be changed, e.g. for creating an event or holidays.
In this case, three timeslots for the second and third game were deleted by clicking the 'x'. They now appear in grey. Two new timeslot were added (yellow). Saving these changes, the new timeslots will appear in the front end for game 2.
