I have this same problem with WordPress 2.9.2 and Atahualpa 3.4.6.
The calendar appears correct on the home page:

But is messed when displaying a posting:

Not sure if this is a WordPress or Atahualpa problem. I’m going to change my theme to see if the problem stays of goes away.

Any ideas, please?
I’m the OP on this thread…just updating my situation, as I’ve removed the calendar entirely. Didn’t end up finding a solution, but instead decided that the calendar was somewhat useless for my purposes.
This is strange, now the calendar is displaying correctly for me???

I’m not sure what I did to get it to work. I’ve been making a lot of changes adding widgets and plugins and tweaking the styles.
