Chanukkah is a pretty significant holiday, although not in the way that it is celebrated in America today.
Chanukkah commemorates two miracles: the fact that the Temple in Jerusalem was re-dedicated and the pure oil that was expected to burn for just one day burned for eight, long enough for more pure oil to be created; and the fact that the Jews won the right to continue to practice their faith despite laws imposed by the conquering Greeks that prohibited circumcision and other important aspects of Judaism.
It is kind of ironic that the holiday that commemorates lack of Jewish assimilation and the freedom to worship G-d as deemed appropriate under Jewish doctrine has become a milquetoast version of Christmas with a menorah instead of a tree for many Jews. I think Christians should celebrate Christmas as they see fit, with songs of faith rather than sleighbells in the snow, and Jews should celebrate Chanukkah as a commemoration of Jews’ right to worship as they believe they are commanded to do.
Let me know when I've said something that isn't true. I said no Jew is supposed to take time off from work because of Chanukkah; and no synagogue ANYWHERE has ANY special service for Chanukkah (unless maybe they're not really Jewish). Compare this with Christians and Christmas, and get back to me.
As for what you said about the two miracles, if you knew what you were talking about you would know that it is one miracle, invented post hoc. (The post hoc miracle of the oil was invented because the Rabbis, 800 years after the fact, as a justification for reciting Hallel as part of the regular services during Chanukkah, needed a miracle. You weren't supposed to recite Hallel except for Biblical holidays or to commemorate miracles. Apparently the victory of the Maccabees wasn't a sufficient miracle so the Rabbis invented the thing about the oil. Otherwise, maybe you know what you are talking about.)
