Tradition
National Day of Remembrance
The National Day of Remembrance is Cambodia's annual day, on May 20, for remembering the victims of the Khmer Rouge regime of 1975 to 1979.[1] The regime killed an estimated 1.7 million people, about a quarter of the population, through execution, starvation, forced labor and torture.[1][2]

The date
May 20 recalls the day in 1973 when the Khmer Rouge began forcing people into cooperatives and doing away with private property in the zones under their control, a policy they imposed across the country in 1976.[2] Collectivization was followed by forced labor, starvation, accusations and executions, and the date is taken as the start of killing on a national scale.[2]
History
The day was first held in 1984 under the People's Republic of Kampuchea as the "Day of Hatred", also called the "Day of Anger".[3][2] It was directed against the Khmer Rouge leadership and also against the government's political opponents of the time.[3]
The observance was renamed the Day of Remembrance. In 2013, acting on a request from the Khmer Rouge tribunal (Extraordinary Chambers in the Courts of Cambodia), the Council of Ministers gave it the name National Day of Remembrance.[2] May 20 was declared a public holiday in 2018 and was taken off the holiday calendar after one year. Ceremonies are held at Choeung Ek on the day each year.[3][1][4]
Observance
The main ceremony is held at Choeung Ek, south of Phnom Penh, where about 2,000 people gathered in 2025.[1] Commemorations include a ceremony attended by Buddhist monks and a re-enactment of Khmer Rouge brutality by students of the Royal University of Fine Arts.[1][5] Researchers at the Documentation Center of Cambodia describe the day as part of remembrance, education and reconciliation for survivors.[2]
