Because of the way November 25 can be read in Japanese ("ii futago") can also translate to "good twins", Japan considers November 25 "Good Twins Day". So, if you're a twin, go pat your twin on the back and if you know a twin, go wish them a happy Good Twins Day.
I'll do a shoutout to a few:
Happy Good Twins Day, you guys!
At the beginning of the month, I wanted to do a little thing where I drew a pair of my favorite twins everyday until today, but I only got to two and a half pairs! D: Oh well, there's always next year? *shrugs*
