The ceremony is being organised by the Tourism Authority and will take place at Bhumibol Bridge, Deputy Prime Minister Gen Tanasak Patimapragorn said Friday.
The bridge was opened by the late King and Her Royal Highness Princess Maha Chakri Sirindhorn at the same time as Ladpho Canal water-gate in 2010.
The event will welcome participants from the government and private sector, plus members of the public.
Songs composed by the King will be performed when the ceremony starts at 5am. Then, at 6.19am, participants will cordially sing the late King’s “The Impossible Dream” and release balloons in memory to the late, beloved monarch, Tanasak said.
Participants will then make offerings to 999 monks and write vows on postcards to commit good deeds in tribute to the late King. The postcards will be blessed in a prayer ceremony and returned to writers as fortuitous objects.
