I hope ye enjoy th' festivities.

I noticed a lot of words changed by itself. Not sure how you did that

Is Pirate day really a thing in some circles? What sort of circles? Is it something like Halloween before the actual Halloween?

I think it's actually type like a pirate day. But maybe for some it's indeed talk like a pirate.

The question emerged because I remember ads like this https://www.visitstaugustine.com/event/st-augustine-pirate-gathering
Apparently it's a very local and limited event as part of a bigger fair or market or circus. I was afraid it could be more significant than this.
