Can You Catch Every Legendary Fish in FFXIV in One Day?

UPDATE: A true, 24-hour legendary day is happening THIS MONTH, March 20-21st, 2026! Yes, I did completely miss it when I was originally hunting for windows. Yes, I am deeply ashamed. See you there! Legendary Fish are some of the most infamous challenges in Final Fantasy XIV, and a big part of that is their extremely low uptime. But what if, by some miracle, all of them just happened to be spawning on the same day? Could such a thing even happen? How close could one person get to catching them all?
