Day of Living Together in Peace 2026

Living together in peace is all about accepting differences and having the ability to listen to, recognize, respect and appreciate others, as well as living in a peaceful and united way.

The UN General-Assembly, in its resolution 72/130, declared 16 May the International Day of Living Together in Peace, as a means of regularly mobilizing the efforts of the international community to promote peace, tolerance, inclusion, understanding and solidarity. The Day aims to uphold the desire to live and act together, united in differences and diversity, in order to build a sustainable world of peace, solidarity and harmony. The Day invites countries to further promote reconciliation to help to ensure peace and sustainable development, including by working with communities, faith leaders and other relevant actors, through reconciliatory measures and acts of service and by encouraging forgiveness and compassion among individuals.

Following the devastation of the Second World War, the United Nations was established to save succeeding generations from the scourge of war. One of its purposes is to achieve international cooperation in solving international problems, including by promoting and encouraging respect for human rights and for fundamental freedoms for all without distinction as to race, sex, language or religion. In 1997, the General-Assembly proclaimed – by its resolution 52/15 — the year 2000 as the “International Year for a Culture of Peace”. In 1998, it proclaimed the period 2001-2010 as the “International Decade for a Culture of Peace and Non-Violence for Children of the World.” In 1999, The General-Assembly adopted, by resolution 53/243, the Declaration and Programme of Action on a Culture of Peace, which serves as the universal mandate for the international community, particularly the United Nations system, to promote a culture of peace and non-violence that benefits all of humanity, including future generations.

The declaration came about as a result of the long-held and cherished concept — contained within the Constitution of UNESCO — that “since wars begin in the minds of men, it is in the minds of men that the defenses of peace must be constructed.” The Declaration embraces the principle that peace is not merely the absence of conflict, but also requires a positive, dynamic participatory process, in which dialogue is encouraged and conflicts are resolved in a spirit of mutual understanding and cooperation. The Declaration also recognizes that to fulfill such an aspiration, there is a need to eliminate all forms of discrimination and intolerance, including those based on race, color, sex, language, religion, political or other opinion, national, ethnic or social origin, property, disability, birth or other status. 2026 Theme: Building Trust through Dialogue, Inclusion and Reconciliation.

Love a Tree Day 2026

Love a Tree Day

Love a Tree Day takes place on May 16, it’s a holiday to show your love for trees, maybe by giving them a great big hug.

Trees play a significant role in reducing erosion and moderating the climate. They remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues. Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are one of the most biodiverse habitats in the world. Trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses.

Wear Purple for Peace Day / Purple 4 Peace

Wear Purple for Peace Day

Wear Purple for Peace Day (Inter-Galactic Wear Purple for Peace Day) is a stellar event, the goal is to make the world a peaceful place and, of course, encourage alien species to make contact with us.

It seems some of you out there fear that aliens from outer space consider earthlings to be too hostile (you’ve got that right). As a result, they have yet to visit or make contact with us. So, some of you (originators unknown) decided to promote world peace by establishing Wear Purple for Peace Day. Wear Purple for Peace Day is celebrated on May 16 every year. It’s a day to promote peace between us and any space aliens who might be lurking about. Obviously the unknown creator of Wear Purple for Peace Day thought that purple would be the one color to signalize aliens that humans are a peaceful species. You should wear a purple ribbon or purple clothing to be part of Wear Purple for Peace Day. The color purple has always been considered a very special color as it is not often to be found in nature. It stands for creativity and supernatural powers. Wear Purple for Peace Day now adds one more expression: being peaceful. If you live in a peaceful country, count yourself lucky on this day.

Neutrinos, the Universe, and Everything (TV Royal Institution)

Particle physicist Kirsty Duffy uncovers the mysteries of neutrinos, and the experiments searching for the answers.

Right now, around 100 billion neutrinos are passing through your thumbnail. You will not feel a single one. These ghostly subatomic particles are the most abundant matter particle in the universe, produced in the sun, in supernovae, at the heart of the Earth, and in bananas. They pass through almost everything without leaving a trace. And yet they may hold the answer to one of the most fundamental questions in all of physics: why does the universe exist?

Vleermuistuintelling 2026

Ieder jaar in mei wordt de verspreiding van vleermuizen onderzocht tijdens de Vleermuistuintelling.

Vleermuizen leven het liefst in buurten met veel groen, water en een donkere nacht. De aanwezigheid van vleermuizen is dus een goede graadmeter voor hoe duurzaam en natuurrijk een buurt is. Ga tijdens de tellingsdagen buiten zitten vanaf zonsondergang totdat het donker is. Zoek daarvoor een plek met vrij zicht op een stuk hemel zodat je de vleermuizen kunt zien vliegen. Liefst ook met zicht op een boom of wat struiken, want daar vliegen vleermuizen graag dichtbij. Noteer hoeveel vleermuizen je tegelijk hebt gezien en van welke soort. Geef de aantallen door via de website van Tuintelling. Er leven bijna twintig vleermuissoorten in Nederland. Zo’n vijf daarvan zou je vanuit je tuin kunnen waarnemen: de gewone dwergvleermuis, de laatvlieger, de gewone grootoorvleermuis, de watervleermuis en de rosse vleermuis. Heb je hulp nodig bij de herkenning? Check dan de handige Vleermuizenzoekkaart van de Zoogdiervereniging, initiatiefnemer van deze telling. Hoeveel vleermuizen zijn er geteld? Welke soorten vleermuizen zijn het vaakst gezien? Wat zijn de verschillen met vorige jaren? Welke trends worden er gezien? De belangrijkste resultaten worden gepubliceerd na de telling op deze pagina.

#RefuseWar #ObjectWarCampaign Conscientious Objection Day / Dag van de Gewetensbezwaarde Militaire Dienst 2026

Dag van de Gewetensbezwaarde Militaire Dienst

Every year, 15th May marks International Conscientious Objection Day (CO day) – a day to celebrate those who have, and those who continue, to resist war, especially by refusing to be part of military structures.

In 2024, on the occasion of International CO day, on 15th May, War Resisters’ International is launching the international action #RefuseWar to support worldwide the refusal of war and the right to conscientious objection. This action is broadening their #ObjectWarCampaign that was launched after the start of the war in Ukraine to call for support and protection for conscientious objectors, deserters, and war resisters from Russia, Belarus, and Ukraine.

Nakba : the Catastrophe (1948) / Nakba 78: Palestinians Call For a Global Day of Action On 15 May 2026

Nakba

The Nakba (Arabic: النكبة, romanized: an-Nakbah, ’the “disaster”, “catastrophe”, or “cataclysm”‘), also known as the Palestinian Catastrophe, was the destruction of Palestinian society and homeland in 1948, and the permanent displacement of a majority of the Palestinian Arabs.

May 15, 2026, marks the 78th anniversary of the Nakba, the forced expulsion of approximately 750,000 Indigenous Palestinians from their homes in 1948. On top of the ruins of our homeland, the Zionist movement established Israel as a settler colony, which has adopted apartheid and military occupation to achieve its declared goal: maximum land, minimum Palestinians. Israel’s livestreamed genocide against 2.3 million Palestinians in Gaza is the darkest chapter in this ongoing Nakba of oppression and ethnic cleansing. Cutting all links of state, corporate, and institutional complicity in its genocidal regime has become an irrefutable legal, not just moral, obligation. Israel seeks to normalize and divert attention from its settler-colonial origins by overwhelming the world with tens of thousands of current crimes against Palestinians and the peoples of the region from Lebanon and Iran to Syria and Yemen. Perpetrating unspeakable depraved violence, it aims to colonize our minds not only with despair but also with amnesia. But Palestinians, like our ancient olive trees, are resilient and patient; we also have a fertile collective memory. Our refugees’ right to return home and receive reparations is our most fundamental goal. We struggle, after all, not just to end the genocide and the ongoing Nakba but also to dismantle their root cause: 78 years of settler-colonialism and apartheid.

The term Nakba is used to describe both the events of 1948 and the ongoing persecution, displacement, and occupation of the Palestinians, both in the occupied West Bank and the Gaza Strip, as well as in Palestinian refugee camps throughout the region. The foundational events of the Nakba took place during and shortly after the 1948 Palestine war, including 78% of Mandatory Palestine being declared as Israel, the expulsion and flight of 700,000 Palestinians, the related depopulation and destruction of over 500 Palestinian villages by Zionist militias and subsequent geographical erasure, the denial of the Palestinian right of return, the creation of permanent Palestinian refugees and the “shattering of Palestinian society”. The expulsion of the Palestinians has since been described by some historians as ethnic cleansing. In 1998, Yasser Arafat proposed that Palestinians should mark the 50th anniversary of the Nakba declaring 15 May, the day after Israeli independence in 1948, as Nakba Day, formalizing a date that had been unofficially used as early as 1949.The Nakba greatly influenced the Palestinian culture and is a foundational symbol of Palestinian identity, together with “Handala“, the keffiyeh and the symbolic key. Countless books, songs and poems have been written about the Nakba. Palestinian poet Mahmoud Darwish described the Nakba as “an extended present that promises to continue in the future.”
