Year 10,000 problem

From Simple English Wikipedia, the free encyclopedia
(Redirected from Y10K)

The Year 10,000 problem (also known as the Y10K problem, Y10K Bug, and Y10K) is an error machines and computers will encounter when they need to express five digits for a year.

Cultural practicing[change | change source]

Some people[1] practice the art of cutting the last two digits of a decade. For example, the "1970's" becomes just the "70's".[2] However, this becomes a problem, because to keep order, one will now need to take the last three digits, rather than two.[3]

Computer Errors due to this[change | change source]

This is also a problem because the "000's" might be confused with the standard digits "00's", representing a new century. Also, the year can overflow with certain computer programs. For example: in Microsoft Excel, 12/31/9999 is considered a valid date, but 1/1/10000 is invalid and will raise errors. The date "ten thousand" is unable to be supported, producing a large negative instead.[4]

Efforts[change | change source]

So far, the Long Now Foundation is able to preempt the Y10K by adding a "0" in front of the date. So the current year of 2023, will look like 02023. However, it would still be affected by the "Y100K" problem.[5]

Database Errors[change | change source]

In MySQL databases, the values of some datatypes are limited to the scope of only 31-12-9999 which causes some problems as the computer would not be able to compile the data in the SQL. Many other SQL software can also be affected by this error.
