- Tree goes up
- Commonly a few days before Christmas Eve, with some households following the German/Austrian 24 December reveal custom and others decorating during Advent
- Tree comes down
- 6 January (Epiphany / Dreikönigstag), similar to neighbouring Germany and Austria
- Local superstition
- No distinctive nationwide superstition documented beyond general Central European norms.
Why that date
Switzerland’s mixed German-, French-, and Italian-speaking regions blend Central European Christmas Eve customs with broader Advent traditions; there is no single nationwide norm.
What actually happens
Confidence note: weaker sourcing than for Germany/Austria specifically; treated as broadly following the same Central European pattern given cultural proximity.
Taking it down again
6 January (Epiphany / Dreikönigstag), similar to neighbouring Germany and Austria. No distinctive nationwide superstition documented beyond general Central European norms.
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.
