3 November: what is celebrated today
3 November is a day of contrasts, where a watchmaker's precision is twinned with the patience of a scientist studying a forest; where the simplest bread can become culinary art, and the colour orange symbolises the silent fight against pain. On this day, humanity looks at itself: in its ingenuity, its fragility and its ability to turn the everyday—nature, food, time and health—into an affirmation of life.
International Day for Biosphere Reserves
Proclaimed by UNESCO in 2021, this day celebrates the planet’s natural sanctuaries: biosphere reserves. They are territories where human beings and nature attempt to coexist without destroying one another, where science and local tradition work together to maintain the balance between development and conservation.
There are more than seven hundred of these reserves worldwide — mountains, rainforests, wetlands, deserts — which act as living laboratories for sustainability. Spain leads the global list, reminding us that wealth is not always measured in gold, but in trees, clean water and shared air. Each reserve is a promise: not to forget that our common home needs constant care, not merely passing admiration.
World Sandwich Day
Not every tribute needs solemnity. World Sandwich Day is also celebrated today, a tribute to the invention of Count John Montagu, who in the 18th century decided to satisfy his hunger without leaving the gaming table. Two slices of bread, a filling, and one of the most universal foods in history was born.
Since then, the sandwich has travelled across cultures and social classes: from the club house of British cafés to the Cuban pressed in iron, from the workers’ bocadillo to modern brunch. Its secret lies not only in its flavour, but in its democratic spirit: it fits in any hand and in any story. In its simplicity, the sandwich embodies what human beings do best — adapt, mix, reinvent.
Sudeck Syndrome Awareness Day
Every first Monday in November, the colour orange recalls an almost invisible illness: Sudeck Syndrome or Complex Regional Pain. Those who suffer from it bear pain that cannot be seen, an inner fire that burns the limbs, alters the nervous system and changes an entire life.
The observance seeks to shine light on that medical shadow, promoting research and empathy. It is not only about science, but about humanity: understanding that another person’s pain, even if we do not understand it, deserves attention and respect. The orange campaigns and marches organised in different countries are an act of quiet solidarity, a way of saying “I believe you” to those who live between pain and hope.
International Jeweller and Watchmaker Day
Time, beauty and precision go hand in hand on this day devoted to the artisans of shine and seconds. It commemorates the birth, in 1500, of Benvenuto Cellini, the Renaissance goldsmith who turned metal into art. In his honour, every 3 November celebrates those who master the craft of giving shape to eternity: jewellers and watchmakers.
Their work demands almost mystical concentration: one millimetre can change everything, a steady hand can determine perfection. They transform matter and time, carving gold or adjusting gears with a patience that seems to defy the accelerated world around them. In their hands, time ceases to be an abstraction and becomes something tangible: a jewel that shines, a watch that beats.
