Is it? I've never noticed a "May Week" at any of the universities I've been
at.

AFAIR, only Cambridge has a "May Week" - originally in May, before the
exams, but now in June after exams. Even there, some colleges prefer
"June event" to the more traditional "May ball". The Oxford equivalent
is the Commem. ball.
