We used to decorate right after Independence day (November 25th) or that's the earliest I would like to do it, but now I don't really do decorations. Maybe I'll change my mind after a few years. What I still do is the cleaning, spending time with family and friends and a lot of food of course hihi
In my family - can't speak for every Surinamese - we (used to) give out Christmas (food) packages to the elderly, with Christmas loaf, food supplies, etc. in it.
