When is Assumption Day?
In 2026, Assumption Day falls on Saturday, August 15, 2026. It is classified here as a Luxembourg public holiday.
History of Assumption Day
Assumption Day is the Christian feast of the Assumption of Mary and a statutory public holiday in Luxembourg. The date reflects the Catholic tradition that has shaped many of the Grand Duchy’s historic public holidays.
Coming in mid-August, it falls during the quieter part of the summer and the school holiday season. Religious services remain significant to many parishes, while the public holiday is also associated with family visits, travel and rural community life.
August 15 remains on its fixed date even when it falls on Saturday or Sunday. Eligible employees who would not normally work receive compensatory leave rather than seeing the feast shifted on the public calendar. Luxembourg guidance normally requires that leave within three months, subject to limited operational extensions. That distinction is especially visible in 2026, when Assumption falls on Saturday but remains officially listed on August 15.
How Assumption Day is observed
A nationwide statutory public holiday on August 15. If it falls on a non-working day, employees may be entitled to compensatory leave under Luxembourg’s employment rules. A non-working-day clash creates compensatory leave rather than moving the holiday’s calendar date.
Traditions of Assumption Day
Church services
Parishes celebrate Mass and local devotional traditions connected to Mary. Times and languages vary between parishes, so local notices remain important.
Summer visits
Families use the holiday for visits, travel and time in the countryside. Many households combine the fixed holiday with annual summer leave.
Village events
Local cultural and religious programmes often take advantage of the August date. Residents should verify whether programmes are devotional, cultural or purely recreational.
Dates and observance rules are checked against the official Luxembourg labour and public-holiday guidance. Bank-sector observances and employer arrangements can differ from statutory national public holidays.
