In addition to the lighting of the Chanukah lights, there are several other important changes made on Chanukah to the daily ritual. They are:
Recital of the Complete "Hallel" on all the eight days of Chanukah
Recital of "Al Hanisim," "(We thank You) for the Miracles" in each "Shemoneh Esray," the 18-blessing, basic Jewish prayer, and in "Bircat HaMazon," the "Grace After Meals".
