Yes, I thought it was an odd thing to say. Maybe he simply meant that virtually every day is a Saint's Day of some saint or other, but relatively few of them actually get the day's worship dedicated to them in any visible (or audible) way. And of course in a typical hymnal, even of the denominations that go in for Saints' Days, only a few saints get hymns of their own. I don't know if that's what he meant, but it might be.
