How to increment date by week?

[PieGuy]

   Starting on any day/date, I would like to create a one year list, by week (start date could be any day of week).  Having a numerical week index in front of date, ie 1-52, would be a bonus.  
   ie, 1.  6/4/2013
       2.  6/11/2013
       3.  6/18/2013....etc to # 52.

   And to save that result to a file.
   Moving from 2.7 to 3.3
TIA
