For every problem, there is one solution which is simple, neat and wrong.
Henry Louis Mencken
Whenever people agree with me I always feel I must be wrong.
Trust the computer industry to shorten 'Year 2000' to 'Y2K.' It was this kind of thinking that caused the problem in the first place.
It is the 23rd day of Tevet in 5760 by the Jewish calendar; the 24th day of 11th month in 4697, year of the earth rabbit in the Chinese tradition; the 10th day of Pausa in 1921 by the national calendar of India; the 24th day of Ramadan in 1420 in the Islamic calendar; but, by our Western tradition it is New Year's Day: the 1st day of the 1st month in the year 2000!
It is also the 1st day of the last year of the 2nd millenium.
