In Linux (at Mandrake Linux) you can specify */5 which would be every (minute,hour,day,etc) that is divisible by 5.
So:
* * */5 * * would be every day divisible by 5 although that's not quite every fifth day due to the fact that months don't end of even divisible by 5 boundaries.
If this option isn't available or isn't "close enough", you may need to run a program/script every day and have the program/script decide if it's been five days since the last time.
