“At that time the Festival of Dedication took place in Jerusalem. It was wintertime, and Jesus was walking in the temple in the colonnade of Solomon.”
~John 10:22,23

Should Christians celebrate Hanukkah?
Hanukkah commemorates the rededication of the temple by Judas Maccabaeus after it had been desecrated and dedicated to Zeus three years earlier.
Unlike the previous two temple dedications, (Solomon’s and Zerubbabel’s), the Jews established a law which required everyone to celebrate the anniversary of this event.
They were not required to travel to Jerusalem, but in this particular case, Jesus did go to the temple for the celebration.
The temple had to be fully functional in Jehovah’s service in order for Bible prophecies to be fulfilled in Jesus. (Da. 9:27; Ps. 69:9; John 2:16,17)
But the Bible does not clarify whether those who had fought to reclaim the temple for Jehovah had accomplished this through divine intervention.
Either way, the temple sacrifices carried out in Jesus’ day served their purpose of being archetypes of Jesus’ sacrifice. (Gal. 3:23-25; Col. 2:13,14,17)
While early Christians were not to judge their brothers and sisters in matters of Jewish tradition, the Greek Scriptures far from encourage the continued observance of traditions relating to Jewish worship. (Col. 2:16; Gal. 4:10,11; Heb. 8:6)
Jesus had foretold the temple’s destruction and the end of traditional Jewish religion as they practiced it.
His prophecy was fulfilled 37 years after his death. (Luke 21:20-24; John 4:21-24; Awake. December 8, 1990. “Hanukkah—Is It a ‘Jewish Christmas'”?)
