There is classical-analysis tag, which is news to me although it existed for a long time. There is no chance of this being used correctly, whatever "correct" means (is it meant to be distinct from non-standard analysis or from "modern-analysis"). It's just randomly attached to any calculus/real-analysis questions. I'm inclined to kill it by retagging. 90 questions so far.
