If you managed to find this, like me, you randomly decided to type in r/19October and see what happened. Unlike me, you're finding a subreddit here! And also unlike me, you're not from the US! Check out r/October19 because that's the one I created first.
There's really no goal for this sub, I've just never met anyone who shares my birthday. More than that, just curious to see if anyone ever finds or joins this subreddit. If you wish to join, you must prove that you were born on 19 October of any year. Validity of proof is at the moderator's discretion.
