How did you end up with 211?

Maybe I'm wrong but how I did :

221 periods of 23 hours
Means for 24 hours it is missing 1 hour
221 x 1 = 221
221 / 24 = 9.20

So around 9 days
221 + 9 = 230 days

Correct me if I'm wrong, maybe too much beers =D

221 x 1 missing h
221 x 24 = 5304 h
5304-221 = 5083 h
5083 / 24 = ca. 211

i think too much beer :P

Mouahaha shame on me =D
Well I go to sleep less dumb now thanks =D
