GOautodial Open Source Omni-channel Contact Center Suite

Hi all.. I make a lot of changes in our GOAutodial 3.3 on CentOS7 from scratch, but what I'm really NOT able to do is to change the order of the callback calendar days. I just would like Monday to be the first day of the week. Can please someone suggest the best way to edit agent.php for doing that?

Here is my code right now from line 3543:

   $CTODAYmday = date("j");
   $CINC=0;
   $live_days=0;
   $limit_days=999;
   if ($callback_days_limit > 0) {$limit_days=$callback_days_limit;}

        }
