- Tree goes up
- Generally early-to-mid December, often influenced by the same post-Sinterklaas sequencing seen in the Netherlands (Flanders) alongside broader Advent practice (Wallonia)
- Tree comes down
- 6 January (Epiphany)
- Local superstition
- No distinctive nationwide superstition documented.
Why that date
Belgium’s linguistic split means Flemish areas share Dutch-style Sinterklaas sequencing while French-speaking Wallonia leans toward general Advent-season timing similar to France.
What actually happens
Confidence note: weaker/generalist sourcing; Belgium’s practice is inferred from its shared cultural ties to the Netherlands and France rather than from dedicated Belgian survey data.
Taking it down again
6 January (Epiphany). No distinctive nationwide superstition documented.
If you would rather not have this argument again next year, the calendar reminder on the home page will put both dates straight into your phone.
