True to an extent. Big ones with 'proof' like 2012 get so much more attention than just random nutters picking a date off a calendar though.

There was a lot of it around the millenium.
After 2001 and the failure of that actually being the real millenium end of the world (surely thats 1995?) they largely seemed to shift their attention to 2012.

That's the next big one I think, 2029 or so? There were big predictions of an asteroid on course for earth (later changed to narrowly missing earth) for sometime around there.
