Not quite in the same context but this works for me:

	#!/usr/bin/perl

	$today=`date -d "next friday" +"%m %d %Y"`;
	#printf("%s\n",$today);
	$candles = `hebcal -c -o -Z israel -C Jerusalem $today`;
	printf("%s\n",$candles);

	$tomorrow=`date --date="next saturday"  +"%m %d %Y"`;
	#printf("%s\n",$tomorrow);
	$havdala = `hebcal -c -o -m 38 -Z israel -C Jerusalem $tomorrow`;
	printf("%s\n",$havdala);
