first of all I would like to have one row with any date in it (formated for a
regular date) example 12/15/04, in the next cell I would like to have
computed the number of the day in the year example 01/10/03 is the 10th day
of the year so that cell would have a 10 in it.

another example is to day 12/15/04 which is day 350.
