These were all the ones the website had listed for today, but some days have more than others. Some have like 10 and then the next day it'll only be one! Seems badly planned but I think people are just making it up.
I guess it could count for anyone who speaks English since that's what the site is in but I don't actually know. Probably it's just a Western world thing.
It was Fairy Day a few weeks back! But I think it's mostly for humans who think fairies are cool, and probably not humans that even know fairies are real.
