use strptime() to parse dates, its much more reliable.

datecode = year + "-" + month + "-" + day
today = datecode

And use strftime() to format them...

print today
print

print "Day of year: ", datetime.date.today().strftime("%j")

This returns todays date whenever you run it.
It has nothing to do with the dates above.
But if you use strptime() to get the date from your string you should then be able to use strftime to convert it to julian.

BTW You say you get it from "database on file".
Now if that is a real database such as SQLite you will find functions there to convert it to julian at source... which is easier than reading it as a string, parsing it, and then converting it back to a date again...
