Ken,
the exploration [select current stock from Jan04, 2000 till now]

x=1+DateNum()-ValueWhen(Cum(1)==1,DateNum());
Cond=x-Ref(x,-1)>10;
diff=Cum(Cond*(x-Ref(x,-1)));
Counter=x-diff+(Year()-2000)*12+Month()-1;
Filter=1;
AddColumn(Counter,"COUNTER",1.0);
gives a good [not perfect yet] calendar counter.
