The International Volunteer Day for Economic and Social Development (5 December), more commonly referred to as International Volunteer Day (IVD), is an international observance mandated by the UN General Assembly in 1985. It offers an opportunity for volunteer-involving organizations and individual volunteers to promote volunteerism, encourage governments to support volunteer efforts and recognize volunteer contributions to the achievement of the Sustainable Development Goals (SDGs) at local, national and international levels. Background International Volunteer Day is celebrated by many non-governmental organizations, civil society, and the private sector, among others. It is also marked and supported by the United Nations Volunteers (UNV) Programme. IVD is a chance for individual volunteers, communities and organizations to promote their contributions to development at the local, national and international levels. By combining United Nations support with a grassroots mandate, the day is a unique opportunity for people and volunteer-involving organizations to work with government agencies, non-profit institutions, community groups, academia and the private sector. United Nations General Assembly resolutions The General Assembly invited Governments to observe annually, on 5 December, the International Volunteer Day for Economic and Social Development (resolution 40/212 of 17 December 1985) and urged them to take measures to heighten awareness of the important contribution of volunteer service, thereby stimulating more people in all walks of life to offer their services as volunteers, both at home and abroad. The United Nations General Assembly, in its resolution 52/17 of 20 November 1997, proclaimed 2001 as the International Year of Volunteers (IYV). The year was conceived to further the recognition of volunteers, facilitate their work, create a communication network and promote the benefits of voluntary service. In 2001, the International Year of Volunteers, the General Assembly adopted a set of recommendations on ways in which Governments and the United Nations system could support volunteering and asked that they be given wide dissemination (resolution 56/38 of 5 December 2001). The United Nations General Assembly, in its resolution 57/106 of 22 November 2002, called upon the United Nations Volunteers (UNV) Programme to ensure that the potential of International Volunteer Day is fully realized. On 18 December 2008, the General Assembly decided that on or around 5 December 2011, two plenary meetings of the sixty-sixth session of the General Assembly should be devoted to the follow-up to the International Year of Volunteers and the commemoration of its tenth anniversary (resolution 63/153).
