7 people are arguing what the current day of the week might be. Each states what he believes to know:

 1. The day after tomorrow is wednesday.
 2. No, wednesday is today.
 3. You are both wrong, wednesday is tomorrow.
 4. Today is not monday, nor tuesday or wednesway.
 5. I think yesterday was thursday.
 6. No, yesterday was tuesday.
 7. Whatever. All I know is that yesterday was not saturday.

All of them, except one, is wrong. What day is it it?
