Opposite of mainstream

How do you define someone that does (not on purpose) quite the opposite of the general trend?

For example:

My week schedule is quite packed with events except Friday evening, while it's usually the opposite we hear about.

I thought of unconventional and peripheral, which I got are antonyms for mainstream, but I am wondering if there is a better adjective for my situation.


I would suggest atypical:

atypical adjective

different from all others of the same type:

  • The sociable behaviour of lions is considered atypical of the cat family.

Cambridge Dictionary


Perhaps unorthodox will work for you:

Unorthodox

  • Contrary to what is usual, traditional, or accepted; not orthodox.

"He frequently upset other scholars with his unorthodox views"

(ODO)


Consider maverick
