Aussie here, to me xmas = summer time. Xmas movies always felt irrelevant, and the idea of Santa wearing all his gear is mental when it's often 40C+ and humid af.
Being cold would feel alien that time of year, even more so if it snowed because that doesn't happen in 99% of the country regardless of the time of year.
also i’ve told some US friends about my new years plans: outdoors, festival, parties kinda thing… they’re blown away by how amazing it sounds for this particular period
actually the closest thing i think we could probably say to americans is: our christmas is like 4th of july… but it’s the whole christmas and new years… we get 4th of july holiday for a whole month or more
