Why are there 8 days and nights for Hanukkah?

Answer 1

Hanukkah is a minor holiday that commemorates the victory of the Jews against the Syrian-Greeks in the Maccabean War of 165 BCE.

A story in the Talmud (500 years later) tells of a legendary miracle. After the war, When the Jews returned to rededicate the Ancient Temple, they found that there was only enough oil to keep the eternal lamp burning for 1 day. It would take 8 days to make more of this special oil. So the lit the lamp, and it miraculously burned for 8 days, giving them plenty of time to make more oil to keep the lamp burning.

Answer:The above answer is non-traditional. Our tradition is that the miracle of the oil did indeed occur and isn't just a legend. If it wasn't for the clear tradition of our Sages, Hanukkah would have been forgotten long ago. Moreover, on Hanukkah the chief celebration is not for the military victory; it's for the miracle of the oil (Talmud, Shabbat 21b). As an augmentation to the celebration of that miracle, we also thank God during Hanukkah for the Hasmoneans' military victory (during which they ousted the Seleucids and their lackeys, the Hellenizing Jews, making possible the rededication of the Temple).

The Seleucids (Syrian-Greeks) under Antiochus Epiphanes (2nd century BCE), at the instigation of the Hellenizers, had forbidden various Torah-practices such as Sabbath-observance, and pressed the Jews to offer up idolatrous sacrifices. The Hasmoneans (a family of religious Jews) fought to retake the Holy Temple, which had been seized by the Seleucids, and to enable the people to once again observe the Torah.

When they reached the Temple grounds and prepared to light the Temple's menorah (Exodus ch.25), they found only one day's supply of unsullied olive oil. Miraculously, the menorah stayed lit for eight days (Talmud, Shabbat 21b), allowing enough time for new oil to be prepared and brought.

The significance of the miracle is that it demonstrated that God's presence still dwelt in the Holy Temple. This is what Hanukkah represents: the closeness to God; and the avoidance of Hellenization (assimilation).

The Torah Sages instituted the festival of Hanukkah at that time (Talmud, Shabbat 21b), to publicize the miracle (Rashi commentary, ibid). The eight-day rededication of the Temple is also mentioned in the book of Maccabees (I, 4:36; and II, 1:18); and Josephus mentions the eight-day festival in Antiquities ch.12.

The Al-Hanisim prayer which we recite during Hanukkah centers around the Hasmoneans' victory, while the candle-lighting commemorates the miracle of the oil.

Though the military victory is prominently mentioned in the prayers, it wouldn't have been celebrated if not for the miracle of the oil, just as we have no special occasion to mark Abraham's victory (Genesis ch.14), or those of Moses (Numbers ch.21), Joshua, Deborah (Judges ch.4), Gideon (Judges ch.6-7), Jephthah (Judges ch.11), or King David. And though the Hasmonean battles continued for two decades after the retaking of the Temple, the Sages instituted Hanukkah immediately after the miracle of the oil.

It should also be noted that the main goal for which the Maccabees fought was not political independence. They fought to enable the people to observe the Torah's commandments; as we say in the Al Hanisim prayer: "the Greeks sought to cause us to forget Your Torah and leave Your statutes."

Answer 2

No, it is not. Hanukkah lasts 8 nights and 8 days. (In the Hebrew calendar, night comes before day.)
