CSS Margin or Padding Issue with the Calendar

I installed the plugin and dropped its shortcode in the page editor. That works as intended, but there is something pushing the calendar down somewhere in the neighborhood of 400 plus pixels. I’ve checked all containing divs, and the calendar divs as well. I also see no errors in the console. I just can’t seem to locate what’s pushing it down. I”m not having this problem on any page other than the one with the calendar, so I’m leaning towards it being something with the calendar CSS causing it, but I just can’t find it.

The page in question can be seen here.
