I am from the UK and I would definitely agree that it is Christmas. People in the UK prepare for weeks in advance, cooking for the big event. It is not just the actual day either. People cook for work and family get togethers at this time of the year and people tend to always have homemade goodies prepared for visitors when they wouldn't normally bother at other times of the year.
I've skipped the last couple of years because sitting there unable to eat any of it while they all complain about me being ungrateful is not how I like to spend my Christmas.
Although Halloween is pretty big as well, and bonfire night. Always recipes in shop magazines for these celebrations, toffee apples, cinder toffee, halloween cookies, etc. But Christmas is the biggest one what with Xmas dinner, Xmas cake, cookies, stollen, etc. so much great cooking at that time of year!
