Two-digit Year Representations
Main article: Year 2000 problem See also: Year 1900 problemFollow-on problems caused by certain temporary fixes to the Y2K problem will crop up at various points in the 21st century. Some programs were made Y2K-compliant by continuing to use two digit years, but picking an arbitrary year prior to which those years are interpreted as 20xx, and after which are interpreted as 19xx.
For example, a program may have been changed so that it treats two-digit year values 00–68 as referring to 2000 through 2068, and values 69–99 as referring to 1969 through 1999. Such a program will not be able to correctly deal with years beyond 2068.
For applications required to calculate the birth year (or other passed year), such an algorithm has long been used to overcome the Year 1900 problem, but it has failed to recognise people over 100 years old.

Famous quotes containing the word year:
“As the Arab proverb says, “The dog barks and the caravan passes”. After having dropped this quotation, Mr. Norpois stopped to judge the effect it had on us. It was great; the proverb was known to us: it had been replaced that year among men of high worth by this other: “Whoever sows the wind reaps the storm”, which had needed some rest since it was not as indefatigable and hardy as, “Working for the King of Prussia”.”
—Marcel Proust (1871–1922)
