Not sure how this is going to help. How to do I configure this with
logrotate?

As far as I am aware logrotate runs daily, and since we want daily log
files I don't see how logrotate is going to know what a 'month' is on a
daily basis. I agree it knows what a 'month' is for monthly log file
rotation, simply because the month (name or number) changes.

What is needed it seems is logrotate to know that the month has changed,
but to keep to the daily log file rotation regardless of what 'rotate'
value is given. That way I get 31 log files for a 31-day month, 30 log
files for a 30-day month and so on.
