20 January: what is celebrated today

Blue Monday: the saddest day of the year

Every third Monday in January, so-called Blue Monday returns as a reminder of the emotional weight that often comes with the start of the year. The formula proposed in 2005 by psychologist Cliff Arnall—a combination of factors such as weather, debt, lack of motivation, or the end of the holidays—never had solid scientific backing, but it did capture something millions of people feel: the inertia of a cold, slow month, where goals wobble and enthusiasm fades.

Beyond its accuracy, Blue Monday works as a contemporary metaphor for discouragement. As communicators and psychologists explain, it is easy to turn a label into a self-fulfilling prophecy if we accept the role of 'sad day' without question. But it is also an opportunity to reverse that narrative: to remember that sadness is not an enemy, but a legitimate emotion, and that choosing how to go through it is part of our mental care. In a world saturated with urgencies, pausing to recognise our own feelings is already an act of resistance.

Martin Luther King Day: memory and justice

The same Monday that some fear for its gloom is, in the United States, a public holiday in honour of Martin Luther King, born on 15 January and a universal symbol of the peaceful struggle against racial segregation. His legacy, built through marches, speeches, and constant threats, transformed the political landscape of the United States and opened spaces of dignity where before there was only exclusion.

The official establishment of the holiday in 1983, after years of social pressure, turned this date into an act of collective remembrance. It is not just about remembering a leader assassinated in Memphis in 1968, but about understanding the ongoing relevance of his message: that civil rights are not definitive achievements, but commitments that must be renewed. Film screenings, civic activities, and volunteering reinforce each year the idea that equality is not an inheritance, but daily work.

Penguin Awareness Day

This 20 January also pays tribute to penguins, creatures that have fascinated for centuries with their clumsy elegance, resilience, and extraordinary community life. Although for a long time it was thought they originated in Antarctica, fossil records point to New Zealand as their evolutionary cradle. From there, they began a slow journey towards the coldest regions of the southern hemisphere, where their bodies—wings turned into flippers, two-tone plumage as camouflage—found a perfect balance between ice and current.

Celebrating this day is a reminder of the fragility of their ecosystems. With 18 different species and growing threats from climate change, pollution, and overfishing, penguins have become indicators of ocean health. Documentaries and environmental campaigns remind us that their survival depends on concrete human actions: protecting the seas, reducing waste, and understanding that when a species disappears, a part of our own world is lost as well.

Semana Europea de Prevención del Cáncer de Cuello Uterino

Coincidiendo with this day, Europe begins a week dedicated to the prevention of cervical cancer, a disease that still causes thousands of deaths despite being, to a large extent, preventable. Information is a vital tool here: knowing the role of the human papillomavirus, attending regular check-ups, receiving recommended vaccines. Each action is a barrier raised against a disease that advances silently.

The week also serves as a space for public awareness. Health institutions, civil organisations, and educational centres promote talks, informational materials, and early screening campaigns. The message is clear: prevention is a right, but also a shared responsibility. In a January so full of symbolism, this date reminds us that caring for health is not an isolated act, but a way of building the future.

Semana de Oración for the Unity of the Cristianos

Finalmente, from 18 to 25 January, different Christian denominations celebrate the Semana de Oración for Unity, a time of reflection marked each year by a different theme. For 2025, the question 'Do you believe this?' resonates as an invitation to review one's own faith, not from dogma, but from coexistence. From Rome to local communities, ecumenical gatherings seek to heal historical divisions and remind us that spirituality can be a meeting place rather than a boundary.

The reflection materials distributed worldwide—including those for young people and children—invite us to think about justice, mercy, and compassion, themes that transcend any tradition. In a global time full of tensions, this week proposes a simple and profound gesture: to recognise oneself in the other, even in what is not shared. A reflection that, in some way, connects with all the commemorations of the day: the sadness we seek to understand, the equality we defend, the nature we protect, and the health we care for.
