a c-section is a risky procedure, and is only done for health reasons of the baby or mother while delivering, if the baby is breeck or a slow heart rate, you dont get to choose a c-section becaue its a big procedure, so they would most likely say no to booking a c-section unless theres a health concern. and like Lilly Ivy said, they would indice you for another reason if you have to have the baby on a certain date.
but.. why are you saying you have to give birth on a specific date? some babies are born like a week late or a week early, or a day late..i highly doubt they would let you have a c-section if you and your baby are doing fine, you should talk to your doctor about when you go into labour and you fearing the pain.
