There are many commercial tools that address various aspects of the Year 2000 problem. None of these tools, however, make any documented use of plan-based techniques for automated concept recovery. This implies a general perception that plan-based techniques is not useful for this problem. This paper argues that this perception is incorrect and these techniques are in fact mature enough to make a significant contribution. In particular, we show representative code fragments illustrating ``Year 2000'' problems, discuss the problems inherent in recognizing the higher level concepts these fragments implement using pattern-based and rule-based techniques, demonstrate that they can be represented in a programming plan framework, and present some initial experimental evidence that suggests that current algorithms can locate these plans in linear time. Finally, we discuss several ways to integrate plan-based techniques with existing Year 2000 tools.
