While I'm sure someone else will provide a much better way, I've used
something like
$ echo $(date -d 20080824 +%j) - $(date -d 20080724 +%j) | bc

That a good idea. I never knew date(1) could do that. The problem,
though, is that it doesn't span years.
$ echo $(date -d 20090824 +%j) - $(date -d 20080724 +%j) | bc

Use delta from epoch, instead.
$ echo $[$(date -d 20090824 +%s) - $(date -d 20080724 +%s)]/86400|bc
396
Why the "/86400"? I follow all of the above but that operation and number.
60 seconds * 60 minutes * 24 hours = 86400 seconds
