16 April: what is celebrated today
Some dates speak in several registers at once. 16 April brings together voice and silence, individual initiative and collective responsibility, the body's fragility and the power of human creativity. It is a day that invites us to listen more closely: to those who raise their voices, to those who still cannot, and to those who imagine new paths amid uncertainty.
World Voice Day
Since 1999, 16 April has marked World Voice Day, promoted by the Federación de Sociedades de Otorrinolaringología. The voice is an extension of the body and also of identity: we use it to work, teach, sing, protest and express affection. In 2025, the motto «Empower your voice» reminds us that caring for it is also a form of respect for oneself and for others.
Common problems such as aphonia — the total or partial loss of the voice — and dysphonia — an alteration in its quality — particularly affect those who depend on it in their daily lives. Constant noise, tobacco, dehydration and vocal overexertion take their toll. This date proposes something simple and unusual: turn down the volume, listen to the body and restore the voice to its natural place, without straining it.
International Day Against Child Slavery
16 April is also a date for remembrance and denunciation. International Day Against Child Slavery is commemorated in memory of Iqbal Masih, a Pakistani child murdered in 1995 after speaking out against forced child labour. His story symbolises a reality that remains current: millions of children around the world are deprived of their childhood through forced labour, trafficking, domestic exploitation, armed recruitment or forced marriages.
This observance does not exist to move people for a few minutes, but to make them persistently uncomfortable. Remembering this day means demanding effective public policies, responsible production chains and active social vigilance. Because no economic progress can be justified if it is built on stolen childhoods.
World Entrepreneurship Day
World Entrepreneurship Day celebrates those who dare to turn an idea into action. Entrepreneurship is not only about founding companies: it is about identifying a problem and seeking a possible solution, even in adverse circumstances. After the pandemic, entrepreneurship also became a strategy for survival, adaptation and reinvention.
Far from the myth of immediate success, this date highlights learning, continuing education and the ability to take meaningful risks. Many current ventures combine technological innovation with social impact, showing that creating economic value and human value are not opposing paths. Celebrating this day means recognising the invisible effort behind every project that begins.
International Wolf-Hirschhorn Syndrome Day
16 April raises awareness of Wolf-Hirschhorn Syndrome, a rare genetic disease also known as 4p syndrome. It affects physical and intellectual development and manifests through characteristic features, growth delay, muscular hypotonia, seizures and cognitive disability.
As with many rare diseases, the greatest challenge is not only medical but social: early diagnosis, access to appropriate therapies and support for families remain uneven. This date seeks to break isolation, encourage research and remind us that inclusion begins when we stop seeing difference as an exception.
World Creativity and Innovation Week
From 15 to 21 April, World Creativity and Innovation Week is celebrated, an initiative promoted by Canadian Marci Segal. It is not an official UN observance, but it has become a global movement that champions creativity as an everyday ability, not one reserved for geniuses or established artists.
This week naturally connects with the other observances of 16 April: creating means giving voice, imagining alternatives in the face of injustice, embarking on new ways of living and designing more humane solutions. In a rapidly changing world, creativity is not an ornament: it is a tool for adaptation and the future.
