Hi Ken,
We noticed this too. In the one case where it was desireable to have calendar entries spidered we were able to inhibit the search engines by elimating many of the views and forward/backward links from the templates. They just were not necessary for this paticular site.
There are a couple of things that I thought might help:
One that is simple to implement, is a configurable limit to the calendar. In many cases you might only need a calendar that goes a year or even a few months or weeks into the future. What we see the spiders doing is going multiple decades ahead and going through thousands of empty calendar days. On the other hand if it was limited to a year forward and back you'd only be looking at about 700 gets a month.
Another would be to eliminate the links for days with no events scheduled. They really are not necessary. All you get when you click on one is a screen that says "No events today". Eliminate those and the users will save a bunch of wasted mouse clicking and the spiders won't be attacking your calendars. Also, in most cases, pages like the year view will display much quicker since the browsers will not need to process the wasted anchor tags.
Best,
Jim Wilson
