Nursing Degree Placement Time Frames

Hi all. I’ve been offered a place at Edge Hill University in September to study Mental Health Nursing. I appreciate different unis may do it differently but I was just wondering when your first placement normally starts and if there is flexibility in how you complete your hours.
I’m part of a drama group and we perform a pantomime every night the first week in December every year. Obviously this wouldn’t be possible if I have no control over the hours at placement. I have been involved in the society for the last 7 years and would love to continue if possible.
I know it may seem early to be thinking about this but we audition in two weeks and there’s no point in me doing the audition if I won’t be able to commit in December.
I’m finding some conflicting advice online. Thanks in advance.
