As I'm sure you must realise that if you are a native English speaker then you don't need to!
But if you are French, then you do need to, at least until you learn a foreign language!
Maybe you should stick with your other four languages. I am not familiar enough with them to know whether they pander to your anti-reflexive preferences.
But in english "how late" equals "what time" so if ” à quelle heure ” can be translated by what time why not how late ! You are say the word tard is not in the sentence but this is An Expression where late is accompanied by the word how !! In your explanation the translation of how late would be comment tard which is wrong !!!
