I've never heard pg actually call it "dday"; I didn't even realize he'd used it in writing on demo day a lot. I honestly would have assumed a reference to WW2 or some kind of military attack if someone said "are you ready for D-Day?" even in a startup context, or maybe a reference to a specific company's launch day, not demo day (by which time most companies have launched)

All I'm saying is, you see the New York Times call YC Demo Day "D. Day" and then someone says they got it wrong because "nobody" calls it "D. Day" and your first response might be to go check that fact out, since that would be an extraordinarily weird mistake for them to make.
