Doomsday 2000

Doomsday 2000, term coined by Canadian computer consultant Peter de Jager in 1993 to describe the operational and financial impact of a defect of contemporary computer hardware and software, known as the Year 2000 problem, that caused computer programs to incorrectly perform arithmetic or logic operations involving a date beyond Dec. 31, 1999. In the late 1990s corporations and governments spent millions of dollars and thousands of hours to correct the problem and avert the potential consequences.
