Yes. You just need to specify the "day of the week" and a "day of the 
month" with a range that can only happen for the first occurrence of the 
particular day in question:

	00 12 1-7 * Fri command-for-first-friday-of-month
	00 12 8-14 * Fri command-for-second-friday-of-month

Remember, cron must match *ALL* date/time specifiers.

I have not tested this, so it may not work as advertised.


Cheers,
