----------------------------------------

Most of these days are celebrated with different and relevant themes every year. Each year’s theme aims to spread awareness about a different aspect of the topic.

Days Recognised by the United Nations

World Radio Day: This day is celebrated on 13 February every year. It recognises the power of radio as a mass medium that has the potential to reach the largest number of people irrespective of social, economic or educational background. Each year, the celebration is centred around different themes.

World Day of Social Justice: This day is observed on 20 February every year to ensure that social justice is upheld globally. Social justice includes removal of discriminatory laws or social practices, championing the cause of women or indigenous people, helping people in conflict areas, and promotion of fair employment policies, among others.

Zero Discrimination Day: 1 March of every year is reserved to raise awareness on the need for inclusive and equal laws and policies. It focuses on the social stigma and discrimination faced by people who are different from the mainstream for any reason. It is spearheaded by UNAIDS (Joint United Nations Programme on HIV/AIDS).

International Day of Happiness: This day is celebrated on 20 March every year to reiterate the importance of staying happy in life and to recognise happiness as a key factor in human growth and development. This day was adopted by the UN General Assembly in July 2012.

World Poetry Day: This day is marked on 21 March by UNESCO to celebrate the ability of poetry to connect different kinds of individuals and the agility of poetry of being both an oral and written tradition.

International Family Day: The UN recognises 15 May as World Family Day to mark the importance of family as the fundamental unit of society and a key to sustainable development of a person, and to increase awareness about the problems faced by families.

World Telecommunication and Information Society Day: This day is marked by the UN on 17 May each year to create awareness about the pivotal role of internet and other communication technologies in society. It also aims to propagate safe digital use and developing and implementing common digital standards across the world.

Global Day of Parents: Apart from the culturally celebrated Mother’s Day and Father’s Day, the international day of parents is marked by the UN to appreciate the role of parents in a child’s life and to honour their love and sacrifices.

World Day Against Child Labour: The UN campaigns on 12 June every year against making children aged 14 or below. This was started by the International Labour Organization in 2002, and it aims to eliminate child labour and encourage companies and governments to create strict policies around it.

World Refugee Day: Lakhs of people each year are forced to leave their homes behind and become refugees in other states or countries because of political or communal conflicts and war-like situations. The UN has set aside 20 June to support the refugees, show solidarity with them, to coax countries to be more hospitable to refugees, and to try and eliminate situations where refugees get created.

International Widows' Day: Widows across the world face several hardships from single motherhood and psychological effects of losing a partner to social stigma. Around 10% of the nearly 258 million widows in the world are poor and almost all of them suffer greatly. The UN has kept aside 23 June to bring awareness to the plight of widows, bring them back to active social life, provide them all the support and opportunities needed, and to empower them.

International Day of Cooperatives: Co-operative societies are an alternative community development model that helps maintain equality and sustainability and empowers its members. The day to honour and encourage cooperative societies is held on the first Saturday of July under the aegis of the United Nations.

World Population Day: Increasing population is a grave problem when seen alongside depleting natural resources. The UN has declared 11 July as World Population Day to bring about awareness on population problems, reproductive health and rights, and work towards sustainable global development.

Nelson Mandela Day: Nelson Mandela set aside his life towards fighting apartheid and inequality. He became the first democratically chosen president of independent South Africa in May 1994. The UN proclaimed 18 July to be Nelson Mandela International Day to encourage everyone to make a difference in their community or region and spread the message of peace and harmony.

International Day of Friendship: Friends are the next most important relationships in a person’s life after family. The UN recognises friendship as an important factor in bringing people together and bridging the various divides – from social to economic to political – existing in today’s world. To honour this, 30 July has been named International Day of Friendship.

Note: This is different from the socially celebrated Friendship Day that falls in August.

International Youth Day: Youth – the age group of 10 to 24 – holds the most promise and can make the most difference in the future of our planet. Currently, the population of youths is over 1.8 billion, but not all of them receive education, healthcare, or equal opportunities. The UN recognises the potential of youths and aims to increase awareness about their problems through this day on 12 August each year.

World Humanitarian Day: This day is observed on 19 August with support from the UN, to recognise the work done by humanitarian workers and aid providers who support crisis-affected people around the world. It is in honour of all the unknown and invisible helpers who put their life on the line and continue lending a helping hand. It also aims to raise awareness about the need for support in conflict or crisis-hit regions.

International Day against Nuclear Tests: The UN General Assembly declared 29 August as the global day against nuclear tests. This day is aimed at generating more awareness on the harm caused by nuclear weapon testing and related explosions. The UN also appeals to countries to stop testing nuclear weapons in order to achieve a nuclear-weapon-free world.

International Day of Charity: Eradicating poverty is not just a governmental or individual effort – it calls for solidarity and compassion from all capable persons. The UN recognises 5 September as global charity day in order to spread the message of helping the underprivileged through charitable activities and philanthropy.

International Literacy Day: Literacy is a key factor in attaining sustainable development in the world. To this end, 8 September is earmarked by the UN to spread awareness on the importance and need for literacy for all, and to urge governments to ensure access to equal opportunities in learning and to quality education.

International Day of Democracy: This day is observed on 15 September to propagate the need for democracy and to emphasise on its importance in sustainability, freedom of speech, and human rights.

International Day of Peace: 21 September is recognised by the United Nations are World Peace Day. All nations are urged to cease all conflicts and enmity for the day and spread more awareness on the need for peace and harmony to support global prosperity and development.

World Maritime Day: This day is observed on 26 September every year under the aegis of the International Maritime Organization (IMO) with support from the United Nations. It aims to promote sustainable shipping and maritime development and to honour the contributions and achievements of the maritime industry.

World Tourism Day: Tourism is now a large contributor to global GDP and job growth. 27 September is celebrated as global tourism day to reiterate the importance of this sector and to propagate sustainable, responsible, and inclusive tourism.

International Day of Older Persons: By 2050, over 20% of the world’s population is projected to be aged 60 or more. Because of this, the UN wants more focus on the needs and care of older persons/senior citizens. 1 October has been identified as the day to increase awareness about the importance of older people, their contributions to society, and the care they need from the younger generation.

International Day of Non-Violence: This day is celebrated on 2 October, the same day as Gandhi Jayanti, to propagate the message of non-violence, tolerance and understanding, and to urge more countries to lay down arms.

World Post Day: Postal services play an important part in communication, interaction, and socio-economic growth across the world, especially in rural areas. This day is observed on 9 October, which is when the Universal Postal Union was set up in 1874 in Bern, Switzerland.

International Day for Disaster Reduction: This day is observed on 13 October and was first observed in 1989. It aims to increase awareness on the importance of controlling risks to natural and man-made disasters and recognises the efforts of individuals and communities in bringing down exposure to disasters.

International Day of Rural Women: The sustainability of rural communities often depends on their women, whether it is through frugality, cooperatives and cottage industries, or informal labour. This day is held on 15 October to urge societies and countries to recognise the role of rural women and improve their living conditions.

United Nations Day: The United Nations was set up on 24 October 1945. This day aims to propagate the messages of the UN and make countries more aware of the organisation and its role in the world. This day is marked by many member countries as a public holiday as well.

World Development Information Day: This day is observed on 24 October every year and calls for more information, awareness, and global cooperation for problems related to growth and development in different countries of the world.

World Day for Audiovisual Heritage: 27 October is earmarked to create awareness about the importance of audio-visual documentation in preserving history, heritage, and culture, and the need to protect these records from being lost or destroyed. Audio-visual modes include radio and TV recordings, movies, shows, and recordings of public performances.

World Science Day for Peace and Development: This day, 10 November, is held to encourage conversations about science and developments in the field and emphasise the significance of science in the progress of humanity.

International Day for Tolerance: As a companion day to the International Days of Peace and Non-violence, this day hopes to encourage co-operation, understanding, and harmony among different communities, cultures, and countries. This day is observed on 16 November.

Universal Children's Day: Though Children’s Day is celebrated in India on 14 November, globally the day for children is 20 November. It aims to improve the living conditions for children and create awareness on the need for them to have a physically and psychologically healthy environment to grow up in.

The United Nations celebrates language days for all its six official languages: English, French, Spanish, Russian, Arabic, and Chinese. They are observed to promote multilingualism and the equal use of each language in the UN.

International Mother Language Day: This is observed on 21 February every year, to promote multilingualism and celebrate diversity of languages and cultures. The observance of this day was proclaimed in November 1999 by the General Conference of the UNESCO (United Nations Educational,

Scientific and Cultural Organization).

French Language Day: This day is observed on 20 March. This day was chosen because on the same date in 1970, the Agency for Cultural and Technical Co-operation (ACCT) – which later became the International Organization of La Francophonie (OIF) – was established.

Chinese Language Day: This day is observed on 20 April. It roughly coincides with the celebration of Guyu that pays tribute to Cangjie, an ancient historian who is believed to be the inventor of Chinese characters.

Russian Language Day: This day is observed on 6 June, which is the birth anniversary of poet A.S. Pushkin.
