Perhaps I was too dry: everything you say is true, but you kinda missed the point ;)
Edit:
In retrospect realise that wasn't particularly helpful. I skipped an awful lot of Mondays for which the only consequence was utter joy at the two cocktail hours every other Saturday. Contrary to the great grandparent, a day really is just a thing.
Sorry, I wasn't clear enough - I didn't miss the point you were making, and I completely agree with it (one of my other comments somewhere on this page makes that same point), I was just pointing out the flaw in your example that travelling forward through time zones many times won't make more of a difference than doing it just once.
