Typically start decorating on or the day after Thanksgiving. I wouldn't mind doing it a little earlier - my job did start decorating for Christmas the beginning of last week which was before Thanksgiving and I didn't mind it. I love decorating for this season!
Most of my holiday decorations are music boxes. I have some really interesting Christmas themed music boxes including a 42 inch limited edition musical porcelain doll and one that looks like a matchbox.
I haven't decorated for Christmas in years, but at a minimum it has to be after Thanksgiving (US) for me. I would have selected December 1st because that honestly feels more appropriate to me, but when I started working I usually found that the only time I had to decorate was on the long weekend after Thanksgiving. I deal with holidays one at a time.
I will do some Christmas shopping earlier if I find something I know I want to get, but I usually do the bulk of my shopping throughout December.
Usually my family and I start decorating either on Thanksgiving day or soon after that. This year is a bit different though. My mom started decorating the inside of the house last week, so it is currently a mix of pumpkins and Christmas decorations. A bit chaotic but I like it.
It's become a very common meme here to start blasting Christmas songs once the -ber months roll over. I think we celebrate it so early because (1) we're predominantly Catholic and (2) we don't usually celebrate any other major holiday between Sept-Dec (we don't have autumn or thanksgiving, and Halloween here is mainly catered towards children).
My family and I started Christmas shopping back in October, for personal reference. We start counting down as far back as 100 days before Christmas. It's a pretty big deal.
Probably the start of December or after Thanksgiving. I don't really have a set time that I do start decorating or celebrating it. I try to do it sooner than later because it's a lot of work to get it all done and have something like 2 weeks of it.
i like putting up decorations after my birthday which is the first week of december, i might be a little later this year as this is the first year in my new flat and i've yet to buy any decorations/tree etc
I like to enjoy the decorations for as long as I can! I put my tree up the day or weekend after Thanksgiving, and the decorations come down after New Year's.
