I fail to see why anyone would get worked up about this.
I don’t know why but when I hear people making these kind of errors I go into a fit of rage. It’s outrageous to me that so many get the starts and ends of decades and the turn of a century wrong.
My husband even locks up our guns during decade changes, afraid of what I might do in our neighborhood. He had me committed on New Year’s Eve 1999 while he stayed up all night to see if our computer would crash. Who’s crazy, huh?
I guess I am more practical. 2000 was a big year for me because it was the year that all computers had to be reprogrammed to work accommodate 4 digit years. Previously most computer had two digit years and the 19 was assumed. Well that was not going to work once 2000 hit, whether or not it was the official start of the millennium or not.
I think that is why the disconnect happened. If we had waited until the official start of the millennium to complete the changes there would be a lot of things that didn't work quite right. And I think that is where all this trouble started.
