The Y2K bug (also known as the millennium bug or simply Y2K) was the result of a practice in early computer program design that caused some date-related processing to operate incorrectly for dates and times on and after between December 31, 1999 and January 1, 2000. This fear was fueled by the attendant press coverage and other media speculation, as well as corporate and government reports. People recognized that long-working systems could break down when the "...97, 98, 99..." ascending numbering assumption suddenly became invalid. Companies and organizations world-wide checked and upgraded their computer systems. Fear of the Y2K "event" caused some people to take extreme measures, such as stocking up on food and weapons.

When January 1, 2000 finally did come around, though, there was no collapse of modern infrastructure. (TXF: "Millennium")
