Welcome to the Q&A Forum

Anthony There's a few ways to do this, and it does depend a little on the specifics of how the site is set up but the best (and easiest) may be to use the URL parameter settings in Webmaster Tools. You're going to log into webmaster tools, go to configuration->URL Parameters - set it to NOT index things beyond the ? (this may be numbers 2 and beyond or it may be everything) How is this set up though? Does the calendar "start" and "end" somewhere or is it going off infinitely in either direction? The robots.txt file won't keep the page out of the index. If you can let us know some more specifics that would be great! -Dan
