Queen Margrethe will officially abdicate on Sunday 14 January, meaning that her son, Crown Prince Frederik, will become King of Denmark on the very same day.
There will be no formal coronation service for the new monarch. The last coronation took place in 1840 for King Christian VIII.
Instead, Frederik's accession will be announced from Christiansborg Palace in Copenhagen on the day.
The Danish royal palace has now confirmed what will happen on the historic day.
Here's a timeline of everything that will happen on 14 January.
At 1.35pm local time, Crown Prince Frederik and Crown Princess Mary will travel by car with Prince Christian from Frederik VIII's Palace at Amalienborg to Christiansborg Palace. Two minutes later, Queen Margrethe will depart in the Golden Wedding Anniversary Coach from Christian IX's Palace at Amalienborg to Christiansborg Palace, escorted by the Guard Hussar Regiment’s Mounted Squadron.
At 2pm local time, Queen Margrethe II will formally abdicate at the Council of State. It will be the first time such an event has occurred in nearly 900 years. She will then return to Christian IX's Palace, Amalienborg.

Of course, the operation also gave rise to thinking about the future - whether the time had come to leave the responsibility to the next generation.
"I have decided that now is the right time. On 14 January 2024 – 52 years after I succeeded my beloved father – I will step down as Queen of Denmark. I leave the throne to my son Crown Prince Frederik."
Queen Margrethe has hosted her last New Year's receptions at Christiansborg palace over the last two days, where she delivered a moving speech. Watch below…
