The bureau published a document in the Royal Gazette earlier this month outlining the royal merit-making ceremonies for the late King, which will be held at the Dusit Maha Prasat Throne Hall.
His Majesty the King will travel from the Ambara Villa of Dusit Palace to the Grand Palace, where he will attend the ceremony at 5pm Friday.
The King will place his personal wreath and a wreath from Her Majesty Queen Sirikit before the late King's royal urn in the throne hall.
Thirty monks will chant prayers after which one monk will give a sermon.
The King will attend the royal merit-making ceremony again at 10.30am Saturday.
After the monks' prayers the King will offer them food.
Another 89 monks will be invited to pray for the late King in the throne hall.
The number matches the age of the late King, who passed away at 88. Thai culture stresses that at the time he was in his 89th year.
Meanwhile, the government has invited the public to observe 89 seconds of silence at 3.52pm Friday.
King Bhumibol passed away peacefully at 3.52pm on Oct 13, 2016 at Siriraj Hospital after a reign of 70 years.
With Friday's first anniversary of his passing, the government has invited people all over the country to make merit.
Prime Minister Prayut Chan-o-cha as well as cabinet members and their spouses will offer alms to the 89 monks at Government House at 7am.
The same ceremony will be held at government offices throughout the country.
"The prime minister would like all Thais to join in the ceremony at a location near their homes and make merit for King Rama IX," assistant government spokeswoman Taksada Sangkachantra said Thursday.
The joint command centre for the royal cremation ceremony held a briefing on the laying of dok mai chan flowers during the royal cremation ceremony, which will run from Oct 25-29.
Sutthipha Nacharoen, director of the general affairs division under the Bangkok Metropolitan Administration (BMA), said the BMA has designated areas for the public to place the cremation flowers at nine locations in Bangkok where the replicas of the royal cremation are situated.
The nine locations are the Royal Plaza, the old head office of the Government Lottery Office, Nagaraphirom Park, King Rama I Plaza, Dhupateme Royal Thai Air Force Sports Stadium, Bitec Bang Na, Buddha Monthon Park, Lan Khon Muang Plaza at City Hall, and King Mongkut's Institute of Technology Ladkrabang.
