Hello! I think your demo is probably correct since that's also when mine ends, but please take that with a grain of salt haha! Have nice day or night! :)

I'm not sure if you have the most recent one or not. The current demo ends after class has happened, but before you leave the school. The prior demo ended while you were in the classroom, but before class had started. So, in either case it's kind of technically still the first day of school.

But if you do have an older version, you can delete that build entirely (that won't erase save files) and then download the demo again.
