Rolling Window

A technique for determining the 

century

 (high-order digits) of 

a

 year that is represented 

in

 two-digit 

format

, which is 

a

 variation on the 

fixed window

 remediation technique.

In

 this method, the pivot 

point

 changes when the system year (usually the 

current

 year) changes.

It

 is also called the 

sliding window

 method.(See
