Thank you from across the pond! 2nd day of Christmas is generally a day we keep clear in our agenda, just because we celebrated Christmas eve and first day of christmas with family this year. I have to work tonight, so I slept a little, played some video games with my kids and that was it. Nice day to have a reason to be even more lazy than I'm usually am.
On mainland europe it is generally called 2nd day of Christmas, in the commonwealth (Britain, Canada, NZ, Australia, in Scotland they call it 2nd day of Christmas again) its boxing day. But most countries don't do a lot on this day, most important are Christmas eve and 1st day of Christmas. A lot of ppl go furniture shopping 2nd day of Christmas, I generally avoid stores, but on days like these for sure. Due to lockdown everything non essential is closed.
