Speak to the people of Israel and say to them, These are the appointed feasts of YHVH that you shall proclaim as holy convocations; they are my appointed feasts.
#leviticus 23:2

The appointed times of #torah belong to God, not man or the Jews. Hanukkah is Jewish. Passover, Shavuot, Sukkot, etc., are not. They are YHVH's. We, the faithful subjects of God's Messiah, whether of Jewish or Gentile ancestry, are responsible for proclaiming a holy convocation on God's holy days. It isn't enough to keep God's appointments spiritually or privately.
