List of minor secular observances in the context of "International Day of Non-Violence"

Europe Day is a day celebrating "peace and unity in Europe" celebrated on 5 May by the Council of Europe and on 9 May by the European Union.

The first recognition of Europe Day was by the Council of Europe, introduced in 1964. The European Union later started to celebrate its own European Day in commemoration of the 1950 Schuman Declaration which first proposed the European Coal and Steel Community, leading it to be referred to by some as "Schuman Day" or "Day of the united Europe". Both days are celebrated by displaying the flag of Europe.

The Black Ribbon Day, officially known in the European Union as the European Day of Remembrance for Victims of Stalinism and Nazism and also referred to as the Europe-wide Day of Remembrance for the victims of all totalitarian and authoritarian regimes, is an international day of remembrance for victims of totalitarianism regimes, specifically Stalinist, communist, Nazi and fascist regimes. Formally recognised by the European Union, the Organization for Security and Co-operation in Europe and some other countries, it is observed on 23 August. It symbolises the rejection of "extremism, intolerance and oppression" according to the European Union. The purpose of the Day of Remembrance is to preserve the memory of the victims of mass deportations and exterminations, while promoting democratic values to reinforce peace and stability in Europe. It is one of the two official remembrance days or observances of the European Union, alongside Europe Day. Under the name Black Ribbon Day it is an official remembrance day of Canada. The European Union has used both names alongside each other.

The remembrance day has its origins in Cold War-era protests in Western countries against the Soviet Union, which gained prominence in the years leading up to the Revolutions of 1989 and that inspired the 1989 Baltic Way, a major demonstration where two million people joined their hands to call for an end to the Soviet occupation. Canadian and other Western communities of refugees from the Soviet Union were instrumental in establishing the remembrance day in 1986. It was proposed as an official European remembrance day by Václav Havel, Joachim Gauck and a group of human rights activists and former political prisoners from Central and Eastern Europe during a conference organised by the Czech Government, and was formally designated by the European Parliament in 2008/2009 as "a Europe-wide Day of Remembrance for the victims of all authoritarian and totalitarian regimes, to be commemorated with dignity and impartiality"; it has been observed annually by the institutions of the European Union since 2009. The European Parliament's 2009 resolution on European conscience and totalitarianism, co-sponsored by the European People's Party, the Alliance of Liberals and Democrats for Europe, The Greens–European Free Alliance, and the Union for Europe of the Nations, called for its implementation in all of Europe. The establishment of 23 August as an international remembrance day for victims of totalitarianism was also supported by the 2009 Vilnius Declaration of the OSCE Parliamentary Assembly.

International Human Solidarity Day (IHSD), observed on December 20, is an international annual unity day of the United Nations and its member states. Its main goal is to recognize the universal value of solidarity by making member states aware of global objectives and initiatives to reduce poverty and to formulate and share poverty reduction strategies of independent nations around the world. IHSD is promoted by the World Solidarity Fund and United Nations Development Programme, which are focused on achieving goals set for worldwide poverty eradication. An individual can participate or celebrate the day, either by contributing to education or by helping the poor or physically or mentally disabled. Governments are instead encouraged to respond to poverty and other social barriers through the Sustainable Development Goals.

The International Day of Peace, also officially known as World Peace Day, is a United Nations-sanctioned holiday observed annually on 21 September. It is dedicated to world peace, and specifically the absence of war and violence, such as might be occasioned by a temporary ceasefire in a combat zone for humanitarian aid access. The day was first established in 1981 and first observed in September 1982 and is kept by many nations, political groups, military groups, and people.

To inaugurate the day, the United Nations Peace Bell is rung at UN Headquarters (in New York City). The bell is cast from coins donated by people from all continents except Africa, and was a gift from the United Nations Association of Japan, as "a reminder of the human cost of war"; the inscription on its side reads, "Long live absolute world peace".

The Fête de la Musique (French pronunciation: [fɛt d(ə) la myzik]), also known in English as Music Day, Make Music Day, or World Music Day, is an annual music celebration which usually takes place in mid-June. On Music Day, citizens and residents are urged to play music outside, in their neighborhoods or in public spaces and parks. Free concerts are also organized, where musicians play for fun; no fees are involved.

The idea for the first all-day musical celebration on the day of the summer solstice came from Jack Lang, then Minister of Culture of France, and Maurice Fleuret; it was celebrated in Paris in 1982. Music Day later became celebrated in 120 countries around the world.

International Students' Day is an international observance of the student community, held annually on 17 November. Originally commemorating the Czech universities which were stormed by Nazis in 1939 and the students who were subsequently killed and sent to concentration camps, it is now marked by a number of universities, sometimes on a day other than 17 November, as a nonpolitical celebration of the multiculturalism of their international students.

It is a public holiday in the Czech Republic, though not due to the day itself, but rather due to the Velvet Revolution, which occurred on the same day in 1989, and started in part as a commemoration of the events in 1939.
