How long was Siff in the loops?

I think when you reach 50-100 loops he says that he doesn't want to know how long he has been stuck like this. But I want to know so Im going to try to break it down.

In each loop it at least takes one day if Siff wakes up at the start in the morning or half a day if he wakes up in the afternoon. And in the castle I think it also takes another day to get through it because its mentioned that it's always night around the king. I think the shortest loop would be when the rock blocks the house maiden's room. So in my sentiments I think Siff looped for about a month. But what do you think.
