month view - number of rows

Hello,
I’ve just noticed that in the month view are sometimey 5 and sometimes 6 rows displayed.

I dont understand when there are 5 rows and when there are 6 rows.

I would like to have either always 5 or always 6 rows - is this possible?
Thanks!

Month view shows all days of month, and based on which week day is first day of month - month can have 5 or 6 weeks, it can’t show always 5 weeks, because in such case some dates will be missed.
