Official flag days in Denmark 2026 and 2027

The official flag days are set out in the Ministry of Justice circular on official flag days of 19 December 2024. On these days, state authorities are obliged to fly the swallow-tailed flag from their buildings. The circular does not apply to private individuals, but the flag days are still the calendar most people in Denmark follow, in the garden, at the summer house and at businesses.

The flag days under the circular

The circular also states that the flag flies at half-mast if a royal birthday falls on Good Friday, and that special rules apply to military flag days. Beyond the fixed flag days, the Ministry of Justice can decide that state authorities fly the flag for special events, such as state visits or occasions in the royal family, and in special cases at half-mast, for example after terrorist attacks or natural disasters.

All dates for 2026 and 2027

The table shows the flag days with their weekday. Good Friday, Easter Sunday, Ascension Day and Whit Sunday are calculated from Easter.

The flags of Greenland and the Faroe Islands

Two of the flag days are marked with a flag other than Dannebrog. On Greenland’s National Day, 21 June, state authorities fly Erfalasorput, which according to Den Store Danske means »our flag« and was introduced in 1985. On Olai Dag, 29 July, they fly the Faroese flag Merkið. Under the Flag Act, anyone in Denmark can fly both flags without permission. More about them in the guide to foreign flags in Denmark.

Church and military flag days

In »Sådan bruges Dannebrog«, Dannebrogs-Samfundet distinguishes between the official flag days and other days on which the flag is traditionally flown:

• Church holidays on which the flag can be flown: Palm Sunday, Maundy Thursday, Whit Monday and Boxing Day. Great Prayer Day is also on the 2019 list, but has not been a public holiday since 2024.
• Military flag days: days commemorating battles and events in the history of the armed forces, for example the Battle of Dybbøl on 18 April. Special rules apply to them, as the circular notes.
• Own flag days: businesses, associations, schools and municipalities can have their own flag days, for example for an anniversary.

Flying the flag on other days

Private individuals can fly the flag whenever they like, within the flag times. Birthdays, weddings, confirmations, graduation parties and visits are common occasions. More about these customs in the guide to flags on holidays and special days, about the flag times in the guide to flag rules, and about half-mast in the guide to flags in mourning.
