Learn English – What do you call a day that is different from the usual days

single-word-requeststerminology

I am looking for a noun or adjective that describes a day that is different from the other usual days, in terms of routine.

My usual routine every day is to stay in the house, do the household chores, feed my dogs, or sometimes go to the mall, stroll, and went back to the house, rest, and the like. My normal days are uneventful and unexciting.

What do you call a day when there's an exciting event happen that made you hyped up and energize?

For example, today I went to the mall and suddenly caught a swindler in the act of asking money from a student, a part of his modus operandi. I caught him, confronted him, and reported him to the authority. We went to the mall's underground basement and helped the security guards file a complaint to the swindler.

My day was different and extraordinary from my usual, boring days.

Consider the phrase red-letter day. Merriam Webster says:

: of special importance : memorable "This was a red-letter day in my life."

It sometimes carries a religious connotation, but this is not necessary. I think Jasmine in the Disney movie "Aladdin" uses it in a song somewhere.
