There's 8 nights of (C)hanuk(k)a(h)

(6) One who buys two trees [that had grown] in property belonging to his fellow brings bikkurim but does not recite the declaration. Rabbi Meir says: he brings and recites. If the well dried up, or the tree was cut down, he brings but does not recite. Rabbi Judah says: he brings and recites. From Atzeret (Shavuot) until the Festival (of Sukkot) he brings and recites. From the Festival (of Sukkot) and until Hannukah he brings, but does not recite. Rabbi Judah ben Batera says: he brings and recites.

(3) There are six months [at the beginning of which] messengers go out.On Nisan because of Pesah; On Av because of the fast. On Elul because of Rosh Hashanah. On Tishri because of the setting of the festivals. On Kislev because of Hanukah. And on Adar because of Purim. When the Temple stood, they used also to go out to report Iyar because of Pesah Katan (Pesah Sheni).

(10) They do not ordain upon the community a fast on Rosh Hodesh, on Hanukkah, or on Purim, but if they had already begun [a series of fasts and one of these days intervened] they do not interrupt [their fasts], the words of Rabban Gamaliel. Rabbi Meir said: even though Rabban Gamaliel said that the [fasts] should not be interrupted he agrees that they should not complete their fasts. And the same applies to the Ninth of Av should it fall on Friday.

(4) On four Shabbatot during and surround-ing the month of Adar, a Torah portion of seasonal significance is read. When the New Moon of Adar occurs on Shabbat, the congregation reads the portion of Shekalim on that Shabbat. If the New Moon occurs during the middle of the week, they advance the reading of that portion to the previous Shabbat, and, in such a case, they interrupt the reading of the four portions on the following Shabbat, which would be the first Shabbat of the month of Adar, and no additional portion is read on it. On the second Shabbat, the Shabbat prior to Purim, they read the portion: “Remember what Amalek did” (Deuteronomy 25:17–19), which details the mitzva to remember and destroy the nation of Amalek. On the third Shabbat, they read the portion of the Red Heifer [Para] (Numbers 19:1–22), which details the purification process for one who became ritually impure through contact with a corpse. On the fourth Shabbat, they read the portion: “This month [haḥodesh] shall be for you” (Exodus 12:1–20), which describes the offering of the Paschal lamb. On the fifth Shabbat, they resume the regular weekly order of readings and no special portion is read. For all special days, the congregation interrupts the regular weekly order of readings, and a special portion relating to the character of the day is read. This applies on the New Moons, on Hanukkah, and on Purim, on fast days, and on the non-priestly watches, and on Yom Kippur.

(6) On each day of Hanukkah they read selections from the portion of the dedication of the altar by the tribal princes (Numbers 7). On Purim they read the portion of “And Amalek came” (Exodus 17:8–16). On the New Moon they read the portion of “And in the beginnings of your months” (Numbers 28:11–15).....

(9) On Rosh Hodesh, on Hannukah and on Purim they may wail and clap [their hands in grief]. Neither on the former nor on the latter occasions may they offer a lamentation. After the dead has been buried they neither wail nor clap [their hands in grief]. What is meant by wailing? When all wail in unison. What is meant by a lament? When one speaks and all respond after her, as it is said: “And teach your daughters wailing and one another [each] lamentation” (Jeremiah 9:19). But as to the future, it says: “He will destroy death forever, and the Lord God will wipe away the tears from all faces” (Isaiah 25:9).

(6) If a spark flew out from under the hammer and caused damage, he is liable. If a camel laden with flax passed by in the public domain and its load of flax entered into a shop and caught fire, the owner of the camel is liable. But if the shopkeeper left his light outside, the shopkeeper is liable. Rabbi Judah says: “If it was a Hannukah light, he is not liable.”

The Sages taught in a baraita: The basic mitzva of Hanukkah is each day to have a light kindled by a person, the head of the household, for himself and his household. And the mehadrin, i.e., those who are meticulous in the performance of mitzvot, kindle a light for each and every one in the household. And the mehadrin min hamehadrin, who are even more meticulous, adjust the number of lights daily. Beit Shammai and Beit Hillel disagree as to the nature of that adjustment. Beit Shammai say: On the first day one kindles eight lights and, from there on, gradually decreases the number of lights until, on the last day of Hanukkah, he kindles one light. And Beit Hillel say: On the first day one kindles one light, and from there on, gradually increases the number of lights until, on the last day, he kindles eight lights. Ulla said: There were two amora’im in the West, Eretz Yisrael, who disagreed with regard to this dispute, Rabbi Yosei bar Avin and Rabbi Yosei bar Zevida. One said that the reason for Beit Shammai’s opinion is that the number of lights corresponds to the incoming days, i.e., the future. On the first day, eight days remain in Hanukkah, one kindles eight lights, and on the second day seven days remain, one kindles seven, etc. The reason for Beit Hillel’s opinion is that the number of lights corresponds to the outgoing days. Each day, the number of lights corresponds to the number of the days of Hanukkah that were already observed. And one said that the reason for Beit Shammai’s opinion is that the number of lights corresponds to the bulls of the festival of Sukkot: Thirteen were sacrificed on the first day and each succeeding day one fewer was sacrificed (Numbers 29:12–31). The reason for Beit Hillel’s opinion is that the number of lights is based on the principle: One elevates to a higher level in matters of sanctity and one does not downgrade. Therefore, if the objective is to have the number of lights correspond to the number of days, there is no alternative to increasing their number with the passing of each day. Rabba bar bar Ḥana said that Rabbi Yoḥanan said: There were two Elders in Sidon, and one of them acted in accordance with the opinion of Beit Shammai, and one of them acted in accordance with the opinion of Beit Hillel. Each provided a reason for his actions: One gave a reason for his actions: The number of lights corresponds to the bulls of the Festival. And one gave a reason for his actions: The number of lights is based on the principle: One elevates to a higher level in matters of sanctity and one does not downgrade. The Sages taught in a baraita: It is a mitzva to place the Hanukkah lamp at the entrance to one’s house on the outside, so that all can see it. If he lived upstairs, he places it at the window adjacent to the public domain. And in a time of danger, when the gentiles issued decrees to prohibit kindling lights, he places it on the table and that is sufficient to fulfill his obligation. Rava said: One must kindle another light in addition to the Hanukkah lights in order to use its light, as it is prohibited to use the light of the Hanukkah lights. And if there is a bonfire, he need not light an additional light, as he can use the light of the bonfire. However, if he is an important person, who is unaccustomed to using the light of a bonfire, even though there is a bonfire, he must kindle another light. The Gemara asks: What is Hanukkah, and why are lights kindled on Hanukkah? The Gemara answers: The Sages taught in Megillat Ta’anit: On the twenty-fifth of Kislev, the days of Hanukkah are eight. One may not eulogize on them and one may not fast on them. What is the reason? When the Greeks entered the Sanctuary they defiled all the oils that were in the Sanctuary by touching them. And when the Hasmonean monarchy overcame them and emerged victorious over them, they searched and found only one cruse of oil that was placed with the seal of the High Priest, undisturbed by the Greeks. And there was sufficient oil there to light the candelabrum for only one day. A miracle occurred and they lit the candelabrum from it eight days. The next year the Sages instituted those days and made them holidays with recitation of hallel and special thanksgiving in prayer and blessings.

It was stated in a dispute between amora’im that Rav said: One may not light from one Hanukkah lamp to another lamp. And Shmuel said: One may light in that manner. The Gemara cites additional disputes between Rav and Shmuel. Rav said: One may not untie ritual fringes from one garment in order to affix them to another garment. And Shmuel said: One may untie them from one garment and affix them to another garment. And Rav said: The halakha is not in accordance with the opinion of Rabbi Shimon in the case of dragging, as Rabbi Shimon permitted dragging objects on Shabbat, even if, as a result, a furrow would be dug in the ground, as it was not the person’s intent to dig that hole. Shmuel said that the halakha is in accordance with the opinion of Rabbi Shimon in the case of dragging.
