It is a Thursday.
Sunday
Monday
4 days after Sunday is Thursday and this is the day before yesterday. Yesterday would mean you have to advance one day, the day b/f yesterday means you have to advance two days. So the day is Thursday + 2 days or Saturday.
If 4 days after the day before yesterday is Sunday tomorrow is... 7-4+2+1 = 6 (Saturday) Forget the first part. Tomorrow is Tuesday. Great question.
Seven days after Sunday is the following Sunday. Since a week consists of seven days, adding seven days to any given day brings you back to the same day of the week.
Sunday.
Thursday- Sunday, 4 days, 18 holes per day.
Seventy-two hours from Sunday at 4 am would be Wednesday at 4 am. This is because there are 24 hours in a day, so 72 hours is equivalent to three days. Therefore, counting from Sunday at 4 am, you would reach Wednesday at 4 am after three full days have passed.

Three days after Sunday would be Wednesday.
