It was just when they would add another digit onto the year. It's like someone thinking that the world will end in the year 10000, because we write the year as 2011 instead of 02011, so the year after 9999 (following this logic) will be 0000, whereas in reality we would just add another digit. The Mayans celebrated when this happened, apparently.
