Date windowing

Date windowing is the system by which full year numbers are converted to and from two-digit years. The year at which the century changes is called the pivot year of the date window.[1] Date windowing was one of several techniques used to resolve the Year 2000 problem in legacy computer systems.[2]

There are three major methods used to determine the date window:

Unix and windows systems have environment variables that set the fixed pivot year for the system. Any year after the pivot year will belong to this century (the 21st century), and any year before or equal to the pivot year will belong to last century (the 20th century). [3]
