The Year 2000 problem, also known as Y2K Effect, computer problem from the year 2000 or Y2K numeronym (in which Y=year or year, 2=two and K=kilo or 1,000), was a bug or software error caused by the habit that programmers had adopted of omitting the century in the year for storing dates (generally to save memory), assuming that the software would only work during years whose numbers began with 19XX. The fear was that computer systems could fail and cause chaos and serious damage of all kinds to countries and companies. Finally, when Saturday, January 1, 2000 arrived, only minor problems were detected, almost anecdotes, which did not cause any significant human, material or economic damage. This was due to the large economic and technological investments that governments and companies made in previous years as prevention, updating these systems to more secure ones. Worldwide, nearly 214 billion euros were invested to avoid the “Y2K effect.” .
