Many people say that a disaster of unprecedented proportions faces mankind on January 1st, 2000.

Some say this is God’s plan to destroy civilization and prepare for the second coming of Christ. Others say that we must give up our political freedom in order to address the impending catastrophe.

At the same time, many scientists and computer experts assert the problems will be relatively minor and easily addressed.

Numerous media commentators and analysts say they don’t know the answers. This is the famous “Y2K” problem. This page contains resources to help you reach your own conclusions.

What is the Y2K Problem?

Computer systems are expected to have certain problems beginning in January 2000 and in the months preceding and following. What are these problems? There are several.


Some programs and databases store only the last two digits of a year. Of these, some perform calculations based on the assumption that the first two digits must be “19”. These computations will be wrong whenever the first two digits should actually be “20”.

Errors of this sort have already happened; for example a prison computer recently released inmates prematurely because it mistakenly computed their sentence to run through year “01”, a number which then appeared to be in the past. Such errors, if uncorrected, would become more common as the year 2000 approaches because more computations will involve periods containing second millennium dates.


Some of the programs and databases just mentioned eliminate the leading digits of dates by subtracting “1900”. These will not fail in the same way, though some of these will have problems when the result of subtraction produces three digits rather than two, or beginning October 10, 2000 when the total digits exceed six.


The sequence “99” is used in some programs not as a number but as a signal of special conditions, such as “missing data”. These programs, if uncorrected, could fail when computing dates in the year 1999.


Some programs fail to compute 2000 as a leap year.


Some calculations work only within a limited range of dates, for example 1903 through 2023. This is not specifically a Y2K problem, though this kind of error is often cited in conjunction with actual Y2K errors.

Taken altogether, this constellation of programming bugs related to the turn of the Millennium is called “The Y2K Problem.”

That there will be errors and that they will have consequences is not debated. After all, nearly all significant programs have errors in them. (We have been living with such errors and their consequences since programming began.) What is debated is how widespread the errors will be, what proportion of them will be corrected before the programs fail, how focused the failures will be on New Year’s Day, 2000 and how serious will be the effects. That is the debate you will find in the resources linked below.

My advice on reading the information is to look for the evidence: Do the authors present facts or suppositions? Do the conclusions follow from the facts or from flights of fantasy? Which comes first, the facts or the evaluation? Does an author reach judgments based on what he does know, or speculations based on what he does not know? If conclusions are warranted by the facts, are the proper judgments drawn or does an author avoid the responsibility of judgment? What conclusions would you draw from the evidence you have?
