A two-minute silence will be held around the UK to mark the anniversary of the World War One armistice.
A number of ceremonies will also take place to remember those who died during that war and all conflicts since.
Veterans and dignitaries will gather at the Tower of London, against a backdrop of an art installation featuring more than 800,000 ceramic poppies.
There will be services in military bases, churches and schools around the UK, and events further afield.
The two-minute silence will be begin at 11:00 GMT.
In London, there will be services at Westminster Abbey, the Cenotaph and Trafalgar Square.
Commemorations have also been organised in northern France and the Menin Gate memorial in Ypres, Belgium.
This year marks the 100th anniversary of the start of WW1, 70 years since the D-Day landings and the end of Britain's conflict in Afghanistan.
Richard Hughes, of the Western Front Association, which organises the Annual Service of Remembrance at the Cenotaph, said this year's commemorations were not just about the end of WW1.
"We have got the modern version here with us stepping back from Afghanistan," he said. "That itself has tremendous resonance."
On Sunday, two-minute silences took place across the UK and the Commonwealth.
The Queen, political leaders and military veterans laid wreaths at the Cenotaph on Whitehall - the focal point of Remembrance Day services.
Armistice Day has been marked on 11 November every year since 1919 - a year after the Allied forces signed an agreement with the Germans that would end WW1.
After the Second World War, commemorations were adapted to honour the fallen of both conflicts, and Remembrance Sunday was established to replace Armistice Day.
From 1995, the British Legion campaigned successfully to restore the two-minute silence to 11 November as well as Remembrance Sunday.
