About National Day
Luxembourg’s National Day is observed on 23 June. The Grand Ducal Court explains that legal texts describe the day as the official public celebration of the anniversary of the Grand Duke’s birth, while “National Day” is the common civic name.
A Grand-Ducal order/decree of 23 December 1961 fixed June 23 as the official celebration date regardless of the Head of State’s actual birthday, and the first June 23 celebration took place in 1962.
Why National Day matters
The modern June 23 date is rooted in the older tradition of publicly celebrating the sovereign’s birthday, not in a claim that the sitting Grand Duke was born on June 23.
Luxembourg’s labour inspectorate currently lists National Day (Grand Duke’s Birthday) on June 23 as a statutory public holiday.
History of National Day
Before the modern fixed date, National Day moved with the sovereign; under Grand Duchess Charlotte it was on January 23, her birthday.
The Grand Ducal Court says the official celebration date was changed to June 23 in 1961 by Grand-Ducal order.
Its historical timeline identifies 23 June 1962 as the first time the sovereign’s birthday celebration was held on June 23.
The fixed June date has been retained under later reigns, even though it does not necessarily match the Head of State’s actual birthday.
