Planned c-section question

So I am currently pregnant with my second. I am only 10 weeks 6 days. My ob told me already that I would most likely have another c-section. So I was wondering if with planned c-sections do you chose your date? Or does the ob? Is it a week or two before? Or on your due date? I know I have plenty of time till this date, but I am just curious. If it was up to me I would have my baby vaginally.
