I want to create a sheet which will tell me what days I'm off on a rotating schedule
The schedule is as follows

Sunday____Monday____Tuesday___Wednesday_Thursday__Friday_____Saturday__Sunday____Monday____Tuesday___Wednesday_Thursday__Friday_____Saturday
04 Sep 16__05 Sep 16__06 Sep 16__07 Sep 16__08 Sep 16_09 Sep 16__10 Sep 16_11 Sep 16__12 Sep 16__13 Sep 16_14 Sep 16__15 Sep 16_16 Sep 16__17 Sep 16
ON_________OFF_______OFF________ON_________ON______OFF________OFF______OFF________ON_______ON_______OFF_______OFF_______ON________ON

And it continues to rotate like this, I want to be able to type in any given date (past, present, or future) and have to automatically tell me if I'm on or off that day, can anyone help me accomplish this?
