MA: I have asked you for a source that states that Hoshana Rabbah is not Chol hamoed.
I believe we’re just arguing over a label here. We all agree that Hoshanna Rabba is a day where melacha is permitted (as on all other Chol HaMoeds) and yet, it has a charachter that is somewhat Yom-Tov like (especially in the davening).
I don’t think whether or not you actually call it “Chol HaMoed” or not has any practical difference.
(On the other hand, unlike Mashiach Agent, I fast on Asara B’Teves when it falls out on Friday. 🙂 )
