My mistake, I think any common day's off of work should be considered. I imagine
that there are some lists available to consider for this topic, but I am not aware
of any good ones at this point. Looking through a bunch of sites online, if all
holidays were considered, there would be no days available, but there will 
probably have to be a line drawn somewhere, and I'm not the person to decide on
that.

I'm not convinced that we need to pay any attention to holidays, or even weekends.  Although I'm willing to be.  

If 5011 is well deployed, and we're testing it every year or two though root KSK rolls, why are we concerned about the day of the week that a change gets applied?  The Internet is 24x7, after all.  What is the middle of the night on a holiday, for you, is business hours on a workday for someone else.  I can't imagine that we could avoid holidays in a balanced way.
