We do a lot of things stupid.
Yes I am an American, but I have to admit it, we (collective) do a lot of things stupid.
We are the ONLY country in the world that hasn't adopted the Metric System! How stupid and arrogant is that?
I don't know what system the rest of the world uses for dates but I use the COMPUTER SYSTEM. lol
As for todays date I use the format 2006-09-09 (Full Year, Month, Day. and note I use leading zeros. That way computer programs can sort by Year, Month, and Day and won't get them out of order.) If you don't use leading zeros the months would look like this. 1,10,11,12,2,3,4,5,6,7,8,9, and the days would be even more messed up.
