What does the “D” stand for in D day?

Dear Terry,
Believe it or not, the term “D-Day” is a generic military term meaning, and I quote, “The unnamed day on which a particular operation commences or is to commence.”
The original codename for the operation which was to ultimately be executed on D-Day was “Operation Roundup”, and it was later changed to “Operation Overlord”. But the actual date on which the invasion was to take place was unnamed, and hence forever known as “D-Day”.
