Why do they call D-Day (Doom Day) 'D-Day'?

It stands for: Debarkation Day. Any assault on a beachhead was labeled D-Day so that planners could have a label to work with. However, June 6, 1944 has overshadowed the rest and has become the one that we acknowledge. Jun 02 04, 8:57 AM

It was just a convenient military codename for the day at which a specific important event was due to happen. The term H-Hour was also widely used and the extra letters didn't stand for anything (despite what one or two articles say about Debarkation Day!) However, I still like to think of the most famous D-Day as short for Normandy-Day.
