I see where that comes from now. Wednesday Bible study and Sunday services. But 10 times per month is not possible. The most would be 9, since no month has 35 days, unless they also had other meetings not so indicated.
As an addendum I should add that when I looked to get an example I noticed you wouldn’t get 10, just 9. I forgot to adjust my post. I wasn’t sure if any month started on a wed and ended on sun, not doing the quick math to eliminate that possibility. At any rate the 8-10 leaves an average of 9 and most months do have either the extra wednesday or extra sunday.
