I think that Christmas at Godrics Hollow was memorable because he went to where his parents were from

Ron and Harry said 'Happy Christmas'. Its so sickening its memorable

Christmas at Grimald Place, Only one he got to have with Sirius and Remus.

Harry's first Christmas. He never got presents before that. He was amazed that he actually got presents.

I think that the Christmas with the Weasleys and Sirius was most memorable ❤ But maybe it's because my favourite character is Sirius and I think he's the best godfather in this whole world. And yeah, this was Harry's and Sirius' only Christmas what they spent together.

His first Christmas

All of them
