I think it could also be cultural difference in the use of the word "holiday". In Britain a holiday is what you'd call vacation, whereas our bank holidays are what you'd call public holidays. We don't generally refer to Christmas and New Year as holidays, even though that's when you take time off work, because you're not "going on holiday".
When I was a kid, it wasn't entirely uncommon to get a big gift during a random holiday get-together.
But I think "holidays" is more of a generic retail term used to get people to buy more and feel less limited.

I had no idea. I think that pretty much explains the confusion then.
