That is literally impossible to have seen that in only a year.
24,312 episodes means 66.608 episodes a day. At 23/min an episode this is 1,531.98min/day and comes out to 25.53hr/day which is literally impossible let alone physically.
Unless you were doing something like watching at 4-8x but even then it would not leave much time for sleep, work and other life-related matters.
I've watched half of 'endless eight' episodes at 4x the speed, and enjoyed it more than would've at normal speed, but that's probably an exception =).
Maybe theyre a heretic that skips the OP and ED of every episode? That cuts down 24 min episodes by like 4 minutes to just 20 minutes.
That puts it at least in the realm of possibility with 66.6 episodes per day taking 22.2 hours.
If you cut out the average opening and ending length of every episode, would it be possible I wonder
"About a year" by that I assume OP is saying that he has watched around 365 days worth of anime.
He's saying he's watched about a year's worth of anime. Not he's only been watching anime for about a year.
That is amazing, i have my account in my anime list, not sure how msny hours but close to 300 days
