My mother who was Catholic rarely celebrated Christmas, at least not at night. Sometimes she would prepare a more sophisticated meal for lunch on 25th. She used to go to bed close to sun set and get up very early, except when I became a teen and stayed up late.
I used to celebrate Hanukkah when I was aiming to convert, and even some years afterwards as a Noachide, just lighting the candles without the bracha. Now I don't light it, it has no sense for a Goy since it's not a mitzva and only to teach the story of the miracle to others. There are no Noahides here and nobody knows what the lights mean.......
