Being a northerner, I was brought up calling any midday meal ( roughly between 11am - 3pm?) 'dinner', even if it was just a sandwich, so our Christmas Dinner was no different.
That said, I've been wracking my brains trying to remember if we still called it that if it was served later instead. I don't think we did - I think it was just 'the Christmas meal'.
Certainly not Christmas tea, anyway - that was always the late afternoon/early evening cold, buffet-type meal served hours after the dinner.
Slightly off- topic now, but did anyone else hear a weather forecaster this last week refer to "bonfire evening"?
I've never heard it called that before in my life - it's always been bonfire night. It sounded most odd!
