Monday, September 5th is the official flag day for Denmark's deployed military personnel.
The date has been the official flag day since 2009 and it will be marked nationwide with a variety of events and ceremonies.
“The flag-flying day is an occasion to express acknowledgement of the outstanding and professional effort, that Denmark's deployed personnel, have made and make today in a number of the world's conflict areas,” the Ministry of Defence writes on its website.
In Copenhagen, the Crown Prince Couple and government representatives will visit the Citadel (Kastellet) for a wreath-laying ceremony at the ‘Monument to Denmark's International Effort Since 1948'.
The monument, established in 2011, has inscriptions of the names of Denmark's fallen military personnel and pays tribute to those current deployed in conflict and catastrophe areas around the world.
At 2pm, Prime Minister Lars Løkke Rasmussen and others will attend a memorial service at the Church of Holmen (Holmens Kirke). There will then be a parade at 3.30pm beginning at Christiansborg Palace Square (Slotsplads), followed by a reception in the parliament building.
Throughout the country, a number of local arrangements will be held in honour of flag day. You can see that list here (in Danish).
The Danish military currently has personnel deployed in 16 different places around the world. Denmark is an active part of the international coalition fighting the terror group Isis in Iraq and Syria. Denmark joined the coalition in October 2014 and Danish F-16s have flown some 550 missions over northern Iraq.
In April, Danish lawmakers approved sending warplanes into Syria and the Danish F-16 fighter jets hit Syrian targets for the first time last month.
Late last month, the Danish military also led an international maritime transport mission to remove around 500 tonnes of chemical weapons from Libya.
