(Y2K, or "millennium bug") A common name for all
the difficulties the turn of the century, or dates in general,
bring to computer users.
Back in the 1970s and 1980s, the turn of the century looked so
remote and memory/disk was so expensive that most programs
stored only the last two digits of the year. These produce
surprising results when dealing with dates after 1999. They
may believe that 1 January 2000 is before 31 December 1999

year 2000 bug
(gcide) | millennium bug \mil*len"ni*um bug`\ (m[i^]l*l[e^]n"n[i^]*[u^]m
b[u^]g`), n. (Computers)
An error in the coding of certain computer programs which
store the year component of the date as two digits, assuming
that the first two digits are 19, rather than as a complete
number of four digits; when such programs are used after
January 1, 2000, the date may be misinterpreted, causing
serious errors or total failure of the program; -- called
also year 2000 bug, year 2000 problem and Y2K bug.
Note: In the several years leading up to the year 2000, large
corporations and other users of computers in total
spent many billions of dollars correcting this error in
the programs they use.
[PJC]year 2000 bug \year 2000 bug\, year 2000 problem \year 2000
problem\, n. (Computers)
an error in the coding of certain computer programs in which
the year portion of dates was represented by only two decimal
digits, assuming that the first two digits are "19". In such
a program the the year 1975 is represented as "75". This was
a common practise in computer programming even into the
1990's, as many programmers failed to consider that their
programs would be used after the year 1999. Thus, with such a
program, a person born in 2000 would be considered as 101
years old in 2001; many different serious problems, as
various as the programs, could be caused by such an error.
Note: In 1998 many programs with the year 2000 bug were still
not corrected, and it is not clear how many programs
will retain the bug when the year 2000 arrives. Tune in
then.
