hello all,
    since I posted this last time, I've added a new function dates_diff and
modified the dates_dict function to set timedelta values returned by
dates_diff in the returned dict

    def dates_dict(self,*targs,**dargs):
        """
            dates_dict() - takes params same as prefs()
                returns dict key/value pair of formatted/calculated dates
                    key is a date, value is timedelta enddate-startdate

        """
        self.prefs(*targs,**dargs)
        d={}
        try:
            if self.format!="":
                d[self.startdate.strftime(self.format)]=self.dates_diff()
            else:
                d[self.startdate]=self.dates_diff()
        except ValueError:
            d["%s"%self.startdate]=self.dates_diff()
        while self.startdate<self.enddate:
            a=self.calc(*targs,**dargs)[0]
            d[a]=self.dates_diff()
        self.reset_dates()
        return d
    def dates_diff(self,*targs):
        """
            dates_diff - return timedelta difference between startdata and
enddate
                takes nothing, a tuple, a list or 2 date objects as params
                return enddate - startdate timedelta

        """
        start,end=(self.startdate,self.enddate)
        if targs:
            if(len(targs)==1):
                if(type(targs[0])==type(()) or targs[0] == type([])):
                    if(len(targs[0])==2):
                        start,end=(targs[0][0],targs[0][1])
            elif(len(targs)== 2):
                if(type(targs[0])==type(date.today()) and targs[1] ==
type(date.today())):
                    start,end=(targs[0],targs[1])
        return end-start
