International Volunteer Day
International Volunteer Day (IVD) mandated by the UN General Assembly, is held each year on 5 December. It is viewed as a unique chance for volunteers and organisations to celebrate their efforts, to share their values, and to promote their work among their communities, non-governmental organisations (NGOs), United Nations agencies, government authorities and the private sector.
