In 2008 at this time of year (that is, the Thanksgiving holiday in the US), I had a post about whether or not I give exams just before a major holiday break (I do not). As usual, there were some interesting comments, but I think this question deserves a poll in 2011.
In this poll, a "No" answer implies a deliberate choice to not give an exam or quiz before a major break (you can explain why in the comments).
An answer of "Maybe" implies that you don't really pay attention to holidays/breaks and you just create the schedule however makes the most sense for the class/topic; if a quiz falls just before (or just after) a break, so be it.
A "Yes" answer implies that you deliberately schedule exams just before a break because .. (explain in the comments); e.g., this ensures attendance, you'd rather give an exam just before than just after a break, you are evil etc.
