@Sean First of all, thank you for your feedback and of course I wish you a speedy recovery as soon as possible.
A plugin would be great.

Since I am still in the initial phase, I will use a different view for now.

@Sean
A calendar, like the picture, only need to Show one or two events per cell.
Than i would have one column for every calendar.
I don’t need a Header for every day. Only one Header at the top with the Namens of the calendar.
And left side the days from top to bottom.

If someone would like to create such a module or still have tips for settings for existing modules, I would be very happy.

@sdetweil
OK. That sounds good. I will try it.
An idea to get an row at the left side with the days?

@sdetweil
First of all, I’m sorry that I have to ask such stupid questions. Sometimes, as a beginner, you simply lack the overview. I have now tried your proposal. Unfortunately, every day has a headline. It would be great if the days had no headline, but the days were to the left of it. Like in the picture. Do you think that is feasible?

@sdetweil
Thanks, for the first that could be the right way.
Do you know the right command for the custom.css to set the font size of the headers and the event lines separately?

@sdetweil
Oh, right, I saw that once. But forget it again. Thank You
