What does D stand for?

Answer 1

Several possibilites exist. Two of the most likely are..... = - = - = If you mean what number is represented by the Roman numeral D - it is 500. = - = - = If you mean what does the first 'D' in D-Day stand for, it just stood for "day", just as the 'H' in H-hour meant the hour at which the D-Day operations all began. There are stories that various days had been chosen as possible invasion dates, and were code-named A-Day, B-Day, C-Day etc. but this is untrue. There was only ever D-Day and it moved backwards and forwards as circumstnaces changed, and eventually June 6th was settled on.
