Denmark observes Flag Day on September 5th, a tradition since 2009, to honor individuals deployed on behalf of the nation. This year marks the 17th observance of flying the Dannebrog to recognize their service.

The day serves as a tribute to those currently or previously deployed for Denmark, as well as a memorial for those who died during deployment. The recognition extends beyond military personnel to include various groups.

Those honored include individuals deployed on missions authorized by the Danish Parliament, the government, or a minister. The day also remembers those who have fallen in service. Personnel from the Armed Forces, emergency services, police, Ministry of Foreign Affairs, and the healthcare system are all recognized for their contributions.

As an official flag day, all state authorities are required to fly the splitflag from their buildings, demonstrating respect and recognition for those deployed in the interest of Danish safety and security.

Official commemorations include a wreath-laying ceremony at Kastellet in Copenhagen, a memorial service for Denmark’s fallen at Holmens Church, and a parade for the year’s deployed at Christiansborg Palace Square. Since 2018, Jutland has also hosted official commemorations, with Haderslev hosting this year.

The initiative for a national flag day to honor deployed personnel came from Senior Constable Kim Eg Thygesen, following his deployments to Kosovo in 2004 and Afghanistan in 2006.

Denmark recognizes 21 official flag days annually.
