day-of-year != julian date

Julian day. (I love the way that article self-adjusts it's examples to the current day.) datecalc implements Modified Julian Day as described in that article:
$ datecalc -j 2007 5 7
54227
$
To convert that to day-of year:
$ echo $(( $(datecalc -j 2007 5 7) - $(datecalc -j 2007 1 1) +1))
127
To convert back, just reverse the operation:
$ datecalc -j $(( 127 + $(datecalc -j 2007 1 1) -1))
2007 5 7
$

I have a shell script which gets passed a parameter which is a combination of Year and Julian Date <YYYYj>. So April 11th, julian date is 101. So if I wanted April 11th for 2003 I would get the following value 2003101. How would I convert that in unix to be 20030411? I am using the korn shell. (3 Replies)
