Seeking advice on wedding planning while at a public school externship

Hello! I'm an SLP grad student and am currently planning my wedding - we're looking at a few different dates right now based on the venue we like: the very beginning of September, end of September, beginning of October, and mid October.

I'll be at my first public school externship this fall and hear that the beginning of the year can be extra busy with evals, meetings, and getting used to the setting in general, so I'm worried about the dates we're considering.

For anyone who's planned a wedding before and works in a school setting - do you think this is feasible? Is there a date that seems better than the other options? Or would you highly recommend trying to find a summer or November date elsewhere?

I'd also appreciate hearing about people's experiences as graduate students in school externships at the beginning of the school year - could you elaborate on how tough it was, how late you were staying, how much paperwork you were bringing home, when you started feeling less overwhelmed, etc? When does "busy season" start and end? Does it never end lol

tl;dr Is a Sept or Oct wedding feasible while at a public school externship? Is one option better/less busy?
