Peace Day is observed in Cambodia every December 29, commemorating the end of the Khmer Rouge insurgency and the civil war in the country. Established in 2024, the holiday celebrates the implementation of the "win-win policy" developed by Prime Minister Hun Sen, which facilitated the surrender of Khmer Rouge forces and contributed to political stability. The day honors the efforts of those who worked tirelessly to achieve peace following decades of conflict that began with the civil war in the late 1960s. In 2024, the holiday was renamed from Win-Win Policy Day to Peace Day and recognized as a national holiday, marking a significant moment in Cambodia's history. The observance serves as a reminder of the struggles faced by the nation and the importance of reconciliation.
