A week is seven days.
They met on sunday and left. Then after a week they no longer had to come every day.
So does this mean that the beginning of their 'week' was monday and the the last day was monday?
It is either six or seven people.
All the people looked at one of the members that had a mark. That person didn't come back. They did this for one weeks time. On the eighth day they didn't have to return. I am going to go with seven people.
