Is this your first time through? I had my first jury duty call last year and it was fascinating. I went through the selection process for three separate trials on my jury duty day. Each time, during the voir dire process, the judge asked jurors to come forward and explain any extenuating circumstance that would result in jury duty being a hardship.

I explained that I was involved in an active emergency response and was irreplaceable on my team, and that because I'm a contractor, I would also suffer financial hardship from jury assignment. All of which was true! As a result they didn't pick me. If something would stress you out enough that you'd be distracted from the trial, they don't want you on the jury. You could definitely go through the selection process, say "I have a work trip that I cannot reschedule tomorrow," and they'll almost certainly let you go.
