is it true that the "d" in D-day really stands for Day?

In English military parlance, D-Day is a term often used to denote the day on which a combat attack or operation is to be initiated. While the initial D in D-day does not stand for anything, it often represents a variable, designating the day upon which some significant event will or has occurred; see Military designation of days and hours for similar terms.\n\nBy far, the best known D-Day is June 6, 1944 — the day on which the Battle of Normandy began — commencing the Western Allied effort to liberate mainland Europe from Nazi occupation during World War II. However, many other invasions and operations had a designated D-Day, both before and after Operation Overlord. D-Day was originally planned for June 5, 1944 but bad weather and heavy seas delayed that.\n\nThe terms D-day and H-hour are used for the day and hour on which a combat attack or operation is to be initiated. They designate the day and hour of the operation when the day and hour have not yet been determined, or where secrecy is essential. There is but one D-day and one H-hour for all units participating in a given operation.\n\nWhen used in combination with figures, and plus or minus signs, these terms indicate the point of time preceding or following a specific action. Thus, H−3 means 3 hours before H-hour, and D+3 means 3 days after D-day. H+75 minutes means H-hour plus 1 hour and 15 minutes.\n\nPlanning papers for large-scale operations are made up in detail long before specific dates are set. Thus, orders are issued for the various steps to be carried out on the D-day or H-hour minus or plus a certain number of days, hours, or minutes. At the appropriate time, a subsequent order is issued that states the actual day and times.\n\nThe earliest use of these terms by the U.S. Army that the Center of Military History has been able to find was during World War I. In Field Order Number 9, First Army, American Expeditionary Forces, dated 7 September 1918: "The First Army will attack at H hour on D day with the object of forcing the evacuation of the St. Mihiel Salient."\n\nD-day for the invasion of Normandy by the Allies was originally set for 5 June 1944, but bad weather caused Gen. Dwight D Eisenhower to delay until 6 June and that date has been popularly referred to ever since by the short title "D-day". (In French, it is called JourJ or Le Choc.) Because of this, planners of later military operations sometimes avoided the term. For example, Douglas MacArthur's invasion of Leyte began on "A-day", and the invasion of Okinawa began on "L Day". The Allies proposed invasions of Japan that would have begun on "XDay" (Kyūshū, scheduled for November 1945) and "YDay" (Honshū, scheduled for March 1946).

Delta simply means "change in".  It is used to indicate a change over a given period of time.  If you are looking for an "average" value, you use "delta N over delta t".\n\nThe "d" as it is used in your question refers specifically to a change over an infinetessimally small period of time.  If you are dealing with a specific point in time, in other words an "instantaneous" value, then "d" is used rather than delta.

The way it was told to me was that the ancient Greeks and Romans decided on one day each for the sun, the moon, Mercury, Venus, Mars, Saturn and Jupiter, the planets visible to the naked eye.  This actually is still reflected in the French names for the days and somewhat it the English names for the days of the week.\n\nLundi - Monday - Moon (la Lune)\nMardi - Tuesday - Mars\nMercredi - Wednesday - Mercury\nJeudi - Thursday - Jupiter\nVendredi - Friday - Venus\nSamedi - Saturday - Saturn\nDimanche - Sunday - Sun

August 15, 1945, marked Victory over Japan Day or V-J Day, taking a name similar to Victory in Europe Day, which was generally known as V-E Day. In Japan, the day is known as, Shusen-kinenbi, which literally means the "Memorial day for the end of the war". The day marks the end of the Burma Campaign, the Second Sino-Japanese War, the Pacific War with the U.S., and other military conflicts in Asia. This is commemorated as Liberation Day in nations such as Korea, partly due to participation of her exiles in War against Japan over 40 years. See Surrender of Japan for historical circumstances surrounding Japan's surrender.\n\nAt noon Japan standard time on that day, Emperor Hirohito's announcement of Japan's acceptance of the terms of the Potsdam Declaration was broadcast to the Japanese people via radio. Earlier the same day, the Japanese government advised the Allies of the surrender by sending a cable to U.S. President Harry S. Truman via the Swiss diplomatic mission in Washington.\n\nSince Japan was the last Axis Power to surrender and V-J Day followed V-E Day by three months, V-J Day marked the end of World War II.\n\nThe formal Japanese signing of the surrender terms took place on board the battleship USS Missouri in Tokyo Bay on September 2, 1945 and at that time Truman actually declared September 2 to be VJ-Day. [1]\n\nV-J Day is now sometimes referred to as V-P Day (Victory in the Pacific Day) to bring it in line with V-E Day where the major enemy power, Germany, was not singled out in the way V-J Day did to Japan. However, since no other power was an Axis belligerent in the Pacific, such alteration of nomenclature seems unnecessary to many.\n\nIn the United States, V-J Day is commemorated on August 14 since the news of the surrender broke on that date in U.S. time zones.\n\nV-J Day is still a state holiday in Rhode Island. The holiday's official name is "Victory Day," and it is observed on the second Monday of August.\n\nIn Australia, the name V-P Day was used apparently from the outset. The Canberra Times of August 14, 1945, clearly states reference to "VP Day" celebrations, and a public holiday for "VP Day" was gazetted by the government in that year according to the Australian War Memorial. Nevertheless, the use of "VP Day" is a subject of controversy in Australia and is seen by some as an instance of political correctness.

Contrary to popular belief, it is not the Mexican Independence holiday(that is in September).  It is celebrated because that day marked the defeat of French forces against the Mexican Army.

Is this a trick question?  The day the ID was issued to the holder.

here is about the only relevant link i could find when i searched for "parachute failure" and d-day:\nhttp://fas-history.rutgers.edu/oralhistory/Interviews/quade_joseph.html\n\nin which this guy who was a paratrooper at d-day talks about one time he can remember chute failure during a training jump.  this out of thousands and thousands of jumps witnessed.  so if it did in fact happen on d-day, i'm sure it was some kind of freak accident.\n\ni get the impression that the paratroopers were very heavily laden with equipment - 70-90 lbs each, and many of them came down in swampy areas, where they drowned under the weight of their gear.  this probably accounts for a far greater number of jump fatalities.

"d" is the answer.\n\nGet an "A".

D is the right answer.

The answer is "daily."  Yahoo! may not want to try to explain it, because if you don't live in the U.S.'s Pacific Time Zone, the "day" can begin at a pretty strange time (like 2 p.m., 9 a.m., etc.).

Been listening to a Seventh Day Advenstist?\n\nLet's consider that Latin, Greek, and Hebrew have numerical values assigned to various letters in their alphabets. In Latin the values are: I = 1, V = 5, X = 10; L = 50, C = 100, D = 500, M = 1,000. By extension W = 10 (because W = VV, or two Vs together), and U = V (because there was no\nletter U for the Romans; where you see the letter U in modern writing, use the letter V instead). \n\nYou claim, correctly, that Vicarius Filii Dei does add up to 666 in Latin: Vicarius = 112; Filii = 53; Dei = 501. (Ignore letters which are not assigned a numerical value.)\n\nThe problem is that Vicarius Filii Dei is not a title of the pope. One of his titles, in fact his chief title, is Vicarius Christi (Vicar of Christ), but, unfortunately for all those who insist on using this ploy, Vicarius\nChristi adds up to only a measly 214, not the infernal 666.\n \nSince the average person, Catholic, Protestant, or otherwise, hasn't the foggiest idea what the pope's titles are in Latin or English, anti-Catholics (some of whom know better) can get away with this subterfuge.\n\nBut what if one of the pope's titles did add up to 666?Would that coincidence prove the pope is the\nbeast? Hardly. It would prove nothing because lots of names and titles add up to 666.\n\nBy using a nifty little technique you can force a Seventh-Day Adventist to admit that the addition to 666 proves nothing, even when it's a papal title that's in questions. \n\n(I'm not picking on Seventh Day Adventists. It's just that the last time I encountered this argument, it came from one. And a nifty little coincidence helped me diprove this person's theory.)\n\nHere's how. Do the math and you will see that the woman who started Seventh-Day Adventism, Ellen Gould White, adds up to 666: Ellen = 100, Gould = 555, White =11.\n\nDoes that fact prove that the foundress of Seventh Day Adventism is the beast?\n\nOf course not, but that would also indicate that Vicarius Filei Dei adding up to 666 is every bit as meaningless as well.\n\nBut, if stubborness rules, and you still want to believe that Vicarius Filei Dei=666=the beast - then you are forced to admit that everyone who's name adds up to 666 is a spawn of Satan. That's just a little ridiculous.\n\nSee? Either way, the claim collapses into absurdity; where it belongs!\n\nHope this helps.
