this is the date reference in cell A2 (1/4/2011) its formatted in English US,
- this is the formulas =IF(A2="","",WEEKDAY(A2)
the result I get is 3, it should be 2, in every case it is calculating a number either die of the correct one.
I know its something to do with the with the date formatting, in excel, but have no idea how to fix it.
I tired just using =IF(A2="","",WEEKDAY(A2)-1) but found dates further down then became incorrect also
