some script-question: date as filename

i would like to have a script for making a backup of my data on a webserver...
i thought of first savin the database to some *sql
and then zipping all files...
...this is no problem, but it would be usefull, if i could rename the files in the way that the date is patr of filename... but how to involve the date into filename?!

the so-far-script:
mysqldump -uusername -p database > ~/www/db.sql 
zip -R -9 -o ~/bak/latestbak ~/www/*

you'd use backticks in the zip command

zip -R -9 -o ~/bak/backup-`date +%m-%d-%Y` ~/www/*

seems to make sense. you would have been able to jsut say date +%D but the standard date output contains /'s which is no use in a filename now is it? good golly no.

DATESTRING=`date +"%Y%m%d"`

One must be very quick here.
Acid_kewpie posted a complete answer while I was pulling together some information to post my short one.

But I have a question: does zip store permissions in the archive? Not so long ago I throwed away zip and rather used tar + gzip for this purpose because zip did not seem to store the permission information with the archived files.
