Luxembourg frames its two sales seasons by law rather than leaving them to each shop. The windows published for the period ahead are listed below; ranges are inclusive.
No dates published for this window yet.
The windows are set by Luxembourg law and published by the administration. This page reproduces the published windows and links to the source it read them from.
Discounting outside the legal sales periods is regulated rather than simply free, and the rules are the administration's to state. Follow the source link for the current wording.
Add this calendar with the button at the top of the page; the sales windows then appear in your own calendar as they are published.
