18 July: what is celebrated today
Some days invite us less to speak and more to understand. 18 July is one of them: a date marked by memory, listening and shared responsibility. From the struggle for human dignity to the defence of a species on the brink of extinction, and through the increasingly forgotten ability to listen to the world around us, this day offers a conscious pause to rethink how we inhabit the planet and live together.
International Nelson Mandela Day
International Nelson Mandela Day is celebrated every 18 July in honour of the birth of Nelson Mandela, one of the most influential moral and political figures of the twentieth century. Proclaimed by the UN in 2010, the day recognises his legacy in defending equality, freedom and reconciliation after decades of apartheid in South Africa.
Mandela showed that justice does not always advance along the path of revenge. After 27 years in prison, he chose dialogue, forgiveness and the building of a collective memory that did not conceal pain but allowed people to move forward. This commemoration recalls that profound change often begins with everyday gestures: an act of solidarity, a community organising itself, a voice raised without violence.
International Vaquita Day
18 July is also a critical date for biodiversity with International Vaquita Day, devoted to one of the planet’s most threatened marine mammals. Endemic to the Gulf of California, this small porpoise is on the brink of extinction, with only a few individuals still alive.
Its situation is not the result of chance, but of human decisions: illegal fishing nets, clandestine trade and inadequate marine-protection policies. Celebrating this day is, in reality, accepting collective responsibility. The vaquita has become an uncomfortable symbol of what happens when economic exploitation advances faster than environmental awareness.
World Listening Day
Less visible, but no less necessary, World Listening Day invites us to stop the constant noise and pay attention to the soundscapes around us. The date coincides with the birth of the Canadian composer and thinker Raymond Murray Schafer, a pioneer of acoustic ecology.
Listening is not merely hearing. It is recognising how sounds influence our health, coexistence and relationship with nature. In a world saturated with stimuli, this day proposes returning to what is essential: attending to voices, silences and surroundings, and understanding that listening better is also a way of caring.
