EXAMS start tomorrow

Exams start tomorrow for me.
I've got one tomorrow (Wednesday)
a second on the day after (Thursday)
my third and last one after the weekend (Monday)

I'm mostly stressed about Thursday.
It's a history course.
The other 2 are English courses.
You live or die on personal ability to comprehend
and make an argument about texts in those courses
Rereading texts studied specified for the exam and
an outline with some pulled quotes are all I can prep

I need 2 out of 3 out of the way before I can get to
Christmas Shopping. Amazingly late, I know. It was
absolutely impossible to be early this ear for anything.
I've been on a steady commute of to a campus, to an
appointment (daily), back home.
I'd rather not get into what the daily appointments are.
They're of a somewhat personal nature that shall remain
nameless and unarticulated (no, it has absolutely nothing
to do with the one sometimes called Babyporridge)

I'm sure I'll throw up the customary MERRY CHRISTMAS
post closer to the date.

Just one question. My family has the main celebration w/ gift opening and dinner
generally on Christmas Eve. We get together on the days after too for food finishing
but yeah.

Who celebrates on Christmas Eve? Who celebrates on Christmas Day? Who celebrates another holiday? Who doesn't celebrate anything at all?
