Y2K

Y2K refers to the “Year 2000” problem, a computer bug related to the formatting of calendar data in software systems. Many systems stored years using only two digits (e.g., "99" for 1999), which created the risk that systems would misinterpret the year "00" as 1900 instead of 2000. The fear was that this would cause widespread software malfunctions in financial institutions, government systems, and other critical infrastructures. Extensive efforts were made globally to fix the issue before January 1, 2000.

Example

Banks, fearing their systems would crash due to the Y2K bug, updated their software to ensure correct date recognition after December 31, 1999.

Key points

• Refers to the "Year 2000" bug in computer systems that stored years using two digits.

• Created concerns that systems would malfunction or interpret the year 2000 as 1900.

• Significant efforts were made to fix software before January 1, 2000, to prevent potential disruptions.
