D-day can be used by military men to call the day when some military operatons will start. And D-day also is a historical date (06.06.1944) This is written in my refence book
I don't know I've just translated the article from my electronic reference book. Maybe it could be used when you're talking about the day which was planned before?
D-Day, H-Hour... they are certainly borrowered from the military, but they can apply to any situation that requires a lot of advance planning. While the most famous D-Day was part of WWII, it's not "the" D-Day, but it was simply "a" D-Day.
For example, if you are preparing for a big software implementation, it wouldn't sound unusual to me to hea
What if we use d-day for the 60th independence day of a country or not necessarily 60th (it could be country's 1st or 2nd independence day),and ,the people of that country are going to celebrate it with great warmth??can we use d-day in this sense ???
