Grand Duke's Official Birthday 2025

The Grand Duke's Official Birthday is celebrated in Luxembourg on June 23, 2025. The public holiday celebrates annually the national day of Luxembourg, thus the holiday is also known as Luxembourg National Day. Though the name is Grand Duke's Official Birthday, no Duke nor Duchess have had his or her birthday on this date. Actually when the leading monarch of Luxembourg is a female, the day is called Grand Duchess’ Birthday. Thousands of Luxembourgers and tourists gather that day to celebrate together and enjoy the torch-lit parade and the fireworks and the biggest street party of the year.
