Don't know what system you are on, but if you have System V date(1) you 
can do: "date +%w" which will display the day of the week (0-sunday, etc)

Otherwise you can just write a quick and dirty c program that
does something like:

	#include <time.h>

	main()
	{
		struct tm * localtime();
		struct tm * t;
		long	    clock;

		time(&clock);
		t = localtime(&clock);

		printf("%d\n",	t->tm_wday);
	}

which gets you the day of the week.
