Does anyone know for this year or remember from years in the past, when they start setting up the Christmas trees outside the malls?
Emquartier, Central World, etc.
I have a friend visiting at the end of October and I can't remember how early they start decorating for Christmas.
TLDR : Answer Summary
In Bangkok, malls like Emquartier and Central World typically begin setting up Christmas decorations, including trees, in early November. While the exact dates can vary annually, they often switch on the lights and have decorations ready by the third Saturday in November. It's advisable to check the malls' official announcements for confirmed dates.
