I've been hearing a lot about the Y2K bug. What was it?

The Y2K bug was a problem that occurred in computer systems around the turn of the century, when computers were expected to be able to handle dates beyond the year 2000. It was caused by a combination of factors, including the fact that many programmers had not accounted for the possibility of having to deal with dates beyond the year 2000, and also the fact that many software programs used a fixed-length integer format for representing dates. This meant that if a program was expecting to represent a date as an integer, and the value happened to be greater than the maximum integer value, then the program would overflow and produce incorrect results.
