Hi ,

I want to convert from today's day to julian day as DDD format.

I have tried the function juliandayfromDate , but it is giving the 7 digit number.
I'm little bit confused whether i can extract the day (DDD which should 3 digit integer) from julian day. Please provide me suggestions on the same. Thanks in Advance.

What exact output do you want? Anything like MMDDD or DDD is not a julian date, hence the issue you are having. Look at the DateToString() function, I believe that a mask of DDD will get you the ordinal day number.

I have heard the term "julian day" incorrectly used to refer to the day-of-the-year before. I'm not sure where this confusing term originates from.
*Edit* It's mentioned here: http://disc.gsfc.nasa.gov/julian_calendar.shtml

Yah, it is (unfortunately) a quite common confusion.
