vTodaysDate = num(Makedate(2009, 4, 30));->        make a date   4/30/2009 if format is MM/DD/YYYY

LET

vCurrentWeekStart = num(weekstart($(vTodaysDate)->  difference of start date and  8/1/2005    

));

LET

vStartDate = num(AddMonths(YearStart($(vTodaysDate)

), - 2 * 12));    

Yearstart of  2 years back or 24 months back

Let

vAdjNum = floor(num($(vStartDate)) - MakeDate

(2003, 1, 1));      difference of start date and  1/1/2003    

Let

vStockAdjMonths = floor((num($(vStartDate)) - MakeDate

(2005, 8, 1)) / 30);                       

difference of start date and  8/1/2005                                                                

hope this helps
