Monthly holidays are mainly memorial days to the annual holiday; these are "yačaraqā ba'āl" ("new moon festival") on the first day of every month, "asärt" ("ten") on the tenth day to commemorate Yom Kippur, "'asrã hulat" ("twelve") on the twelfth day to commemorate Shavuot, "asrã ammest" ("fifteen") on the fifteenth day to commemorate Passover and Sukkot, and "ṣomä mälěya" a fast on the last day of every month. Daily holidays include the "ṣomä säňňo" (Monday fast), "ṣomä amus" (Thursday fast), "ṣomä 'arb" (Friday fast), and the very holy "Sanbat" (Sabbath).
