As the manager of a vulnerability research team, I almost always organise my team's meetings to start at 13:37. It's become customary for us to refer to it as "leet o'clock".
Similar to "the game"[0] (you all just lost), for many years in a group of friends we'd text each other "leet" at 13:37 whenever we'd notice and whoever did it first won that day. Obvious gentleman's agreement to not just use an alarm clock and notice it naturally during the course of the day. Have been doing it for about 20 years now with one of them that kept it up.
I'm shocked that you do this to be honest, because I have my friends and I also do this. I didn't realize that we weren't alone. Not that I thought we were special, moreso that we didn't think anyone else would want to do something so silly.
Looks from the profile the other user is from Canada and I was referring to a friend group from childhood in Portugal, none of which are in Canada nowadays. I think we're just not so special :)
I am born at leet o'clock. Usually I say 13:40 for rounding reasons and before today I never thought about it this way, even though I am familiar with leet speak. But from this day on I'll be proud of my birth time, no more rounding.
Erm, there is a superstition in my region/country that say that you're sleepy at your birth time. So when I was in school, and I had hours at school until 2 PM (6 hours from 8 AM to 2 PM) and I was sleepy around that time then my mother revealed to me that I was born at 13:37, so that's how I know. And you know how parents are, they like to repeat some stuff throughout your life, like it or not. So I got drilled in my head what my birth hour:minute is.
L33t o'clock has been a thing for me for years now. I experience that weird phenomenon where you look at a clock and it happens to be 11:11, except for me it's 13:37 and I'm like "hey, it's l33t o'clock!"
There's another one I call "Razor o'clock" at 7:11 pm, i.e., 19:11.
