  The values are just the number of the day of an year. I have got year in one column, and just the julian day ( as say, 245) in the next column.

  I did try the code, changing the length of the character to 3, but it might vary too, because the julian day values range from 1 - 365/366.

  Any more help...

  Thanks A Lot!

  declare @yr float, @jd float

  select @yr = 2002, @jd = 245

  select dateadd(yyyy, @yr - 1900, -1) + @jd

  Why are there so many complex queries out there to do something really simple?

  declare @julian-2 int

  select @julian-2 = datepart(dayofyear, '2003-01-01')

  Select dateadd(dd, @julian-2, '12-31-2002'), @julian-2

  Obviously there would have to be some decision on what the year was (stored in column, current year, whatever).

  I must be missing something...
