This is how your week goes

It is Monday morning. The door to your work weighs 1000 kilograms. You have a secret, special PIN you must enter before you can open the door to your work. It is your date of birth. There is a guard outside the room where the door and PIN pad are.

If the guard looks up from her Sudoku and winks under her cap, you should progress to the door and enter your PIN.
