What does the "D" in D-Day stand for?
Okay, a little bit of a trick question if you saw the "On This Day" section of our newsletter, BUT, believe it or not, this is a bit of an unknown fact, especially to those outside of the military world. Generally, D-Day is used for the day an operation or event will take place, along with H-Hour, which is "the specific time at which an operation or exercise commences, or is due to commence."
There are a ton of other military designations for days and hours, but the D-Day as we know it is pretty much synonymous with the Normandy Landings that took place on this day in 1944. When Allied powers crossed the English Channel it marked the beginning of the liberation of Western Europe from Nazi control during World War II.
