Y2-What?

I was teaching about doomsday predictions about a week ago.  I used global predictions of disaster to set up my talk about panic over running out of resources.  As specific examples, I used the Family Radio prediction about the end of the world in May of 2011 and the timely Mayan Calendar example.  I also mentioned the Y2K thing and almost none of my students knew what that was.  I had to explain that people freaked out about 12-31-99 rolling over to 1-1-00 would throw off computers and how early computer programmers didn't have the space to put 12-31-1999.

I guess most of my students were 6 when this happened.  I feel like it's a relatively current event, but I didn't think about my audience enough when using that example.
