If you get picked for a jury, they ask you "Does anyone have an issue with a X Day/Y week Trial"?
I had a weekend get away planned and said that in 4 weeks (or something) I would need to leave early on Friday before Columbus Day and Need off Columbus Day. The Judge said "no problem"....in deed that happened (even though we were in deliberations).
Somebody else had a cruise around that time...they were made a alternate juror during deliberations and then were excused to go on their cruise while we deliberated as there was still another alternate available.
My advice is if that date works for you in general, show up for jury duty....If you have to (call the night before), and If you get picked for a trial, and if that is a long trial, then you still will be okay.
