The date of World NGO Day is always February 27. The term "non-governmental organisation" is abbreviated as "N.G.O." The purpose of World NGO Day is to acknowledge, commemorate, and celebrate the vital contributions and significant effects that these autonomous organisations have had on the globe. Nonprofit organisations (N.G.O.s) have a long history despite being a relatively recent development. In the modern world, their influence is expanding and bringing about good improvements where they are required.

World NGO Day is a recognised international holiday that takes place on February 27 every year. The international day honours all those who work tirelessly for social causes around the world in the NGO sector and recognises their significance to society.

World NGO Day is observed annually from New Zealand and Australia to North and South America, uniting supporters from the NGO sector, leaders from the public and private sectors, multilateral and bilateral organisations, local communities, educators, students, and subject-matter experts.
