Hallel consists of six Psalms (113–118), which are recited as a unit, on joyous occasions including the each day of the
Three Pilgrimage Festivals (
Passover,
Shavuot, and
Sukkot), as well as at
Hanukkah and
Rosh Chodesh. On all these occasions, Hallel is recited as part of the morning
Shacharit prayer service, following the
Amidah. In addition, it is recited in many communities during the evening prayers on the first (and, outside
Israel, second) night of Pesach; however, according to the original
Nusach Ashkenaz it is not recited at this time, and thus it is not recited in communities such as
Litvaks (although most Litvish communities in Israel do recite it) and
Yekkes. It is recited in all communities during the
Passover Seder service. According to the
Talmud, there was a dispute between the
Houses of Hillel and Shammai regarding the reading of Hallel during the Seder. According to the school of Shammai, only the first psalm (Ps. 113) should be read before the meal, whereas the school of Hillel advocated reading the first two psalms (Ps. 113 and 114). The remaining Psalms would be said after the
Grace After Meals (as is usually the case, the
halacha follows the school of Hillel). On
Rosh Hashanah and
Yom Kippur, Hallel is not said at all, because as the Talmud states: "Is it seemly for the king to be sitting on His Throne of Judgment, with the Books of Life and Death open before Him, and for the people to sing joyful praises to Him?" No Hallel is recited on
Purim, despite the fact that there was a miraculous salvation. The Talmud suggests three reasons for this: • The miracle did not occur in the
Land of Israel and, for "lesser" holidays, only those occurring in
Israel merit the recitation of Hallel. • The redemption was not complete: after the Miracle of Purim, Jews remained subjects of the
Achaemenid Empire (whereas on Hanukkah, Jews gained their independence from the
Seleucid Empire). • Reading the
Book of Esther is considered a form of Hallel. Partial Hallel is recited on the last six days of Passover and on
Rosh Chodesh. On all other occasions when Hallel is recited, the text is the full Hallel. Many Jewish communities, especially those which identify with
religious Zionism, recite Hallel on
Israeli Independence Day and some also recite it on
Jerusalem Day. The
Chief Rabbinate of Israel instructs Jews to recite Hallel during Israeli Independence Day. ==Other Hallel sequences==
