What does Y2K mean?

Year 2000 (Y2K) problem, also known, as the Millennium bug, the Y2K bug, or simply Y2K, refers to a computer bug that was a concern as the year 2000 approached. The issue arose from the way many computer systems and software programs represented years in dates using only the last two digits. For example, the year 1999 would be represented as "99" and the year 2000 as "00".
As the year 2000 approached, there were concerns that computer systems and software that relied on this two-digit year representation might interpret the year 2000 as 1900 instead of 2000. This could potentially lead to errors and malfunctions in various systems, including financial, industrial, transportation, and utilities sectors, among others.
