About International Human Solidarity Day
International Human Solidarity Day is observed on 20 December. Proclaimed by the UN General Assembly, it celebrates unity in diversity and stresses to governments and people that working together is essential to ending poverty and meeting shared goals.
The UN General Assembly proclaimed 20 December as International Human Solidarity Day. The UN describes solidarity as one of the fundamental values that should guide relations between people in the twenty-first century. Solidarity means that those who have more help those who have less, and that people facing common challenges share both the burdens and the benefits.
The day is linked to the UN's work to end poverty. It rests on the idea that no country or community can solve big problems alone.
How it is marked
The UN and civil society groups hold events on cooperation and shared development goals. Governments are encouraged to keep their international commitments, and people are encouraged to take part in efforts against poverty. Schools run activities on unity in diversity, teamwork and helping others. Community groups organise drives to support people who are struggling, and many people use the day to reach out to neighbours who may be isolated.
