If you have an event that cannot be described with a single image, then consider using a checklist.
A checklist can contain several steps that you need to go through. For example, it could be your morning routine. If necessary, look at this little video on this page understand what checklists are.
You can view a checklist directly from the checklists window, or you can add a checklist to the calendar as a task to complete.
If you view a checklist directly from checklist window (f.x. if you have a checklist describing a recipe), you can still complete each step of the checklist. The green checkmarks will disappear once every day.
