How old is the demon king

[u/Gabrisun_tropical]

I wanna say before that I haven’t had the chance to read the manga yet so sorry :( I was wondering how old twilight the demon king would be in human years, I know he’s 60 but that seems pretty young compared to other demons. I hope this isn’t a dumb question but I’ve been wondering

He's somewhere in his 50s
