1. The clue is the calendar on the wall.
You have to figure out what JASOND stands for.
JASOND stands for July(J, 7th month), August (A, 8th month), September (S, 9th month), October (O, 10th month), November (N, 11th month), December (D, 12th month).
Since only JAS and D are green, only use those months to get the code:
July = 7
August = 8
September = 9
December = 12
Press the keypad and enter 78912.
