What was pol pots year zero fom the cambodian genocide?

Year Zero refers to the period beginning on April 17, 1975, when Pol Pot and the Khmer Rouge regime took control of Cambodia. This date marked the start of radical social and economic reforms aimed at creating a communist agrarian society, resulting in the forced evacuation of cities, mass executions, and widespread persecution. The regime sought to eliminate perceived enemies and revert the country to a primitive state, leading to the deaths of an estimated 1.7 million people during the Cambodian genocide.
