International Day of Happiness

What Is International Day of Happiness?

Every year on March 20th, the world observes "International Day of Happiness." It was established by unanimous agreement of all 193 UN member states at the General Assembly in June 2012. Based on the idea that the pursuit of happiness is a fundamental and universal human goal, the day encourages societies to value people's happiness and well-being -- not just economic growth. Bhutan, the country that proposed the observance, had a major influence on the world with its concept of Gross National Happiness (GNH).

Measuring Happiness: Indices and Surveys

Happiness isn't just subjective -- it's analyzed through a wide range of data.

• The World Happiness Report: Published each year around this time by the UN Sustainable Development Solutions Network (SDSN), the report ranks countries based on factors like GDP, social support, healthy life expectancy, freedom to make life choices, and generosity.
• The stability of Nordic countries: Finland, Denmark, Iceland, and other Nordic countries have consistently ranked near the top for years, reflecting strong social safety nets and excellent work-life balance.

The Psychology and Neuroscience of Happiness

Specific neurotransmitters are at work in the brain when we feel happy.

• The four "happy chemicals": Dopamine (a sense of achievement), oxytocin (trust and affection), serotonin (emotional stability), and endorphins (euphoria) are all scientifically linked to our experience of happiness.
• Well-being: Beyond momentary "joy," the modern concept of "well-being" -- a sustained state of physical, mental, and social fulfillment -- has become the standard definition of happiness in contemporary society.

Interesting Facts About Happiness

• Income and happiness: Happiness tends to rise with income up to a certain point, but research suggests that beyond a certain level (roughly the equivalent of an annual income of 8-10 million yen), additional income has little effect on happiness -- a "saturation point."
• Gratitude journaling: Studies in psychology have shown that the habit of writing down three things you're grateful for each day ("three good things") can reduce depression and significantly increase happiness.
• The importance of connection: A Harvard study spanning more than 80 years concluded that "good relationships" are the single most important factor for health and happiness.
• Bhutan's commitment: Bhutan's constitution states that the government must work to create conditions for the happiness of its people, and the country measures its development through Gross National Happiness (GNH) rather than GDP alone.
• Happiness in Japan: Japan often ranks in the middle among developed countries in happiness surveys, with comparison to others and anxiety about the future often weighing on people's sense of well-being -- though a deep cultural tradition of finding contentment in nature, daily life, and "knowing what's enough" remains strong.

Ideas for Observing International Day of Happiness

• Write down the moments when you feel truly at ease, and prioritize your own values over others' expectations
• Say "thank you" or do something small and kind for someone close to you, and share in the warmth that good relationships bring
• To mark the day, put down your phone, take a walk in nature, or breathe deeply, savoring the mindful contentment of being present in the moment
• Take part in a small activity that helps others or your community -- donating, volunteering, or cleaning up -- and notice the deep sense of self-worth that comes from contributing

A Smile and a Sense of Fulfillment Can Ripple Outward Into a Chain of Happiness

March 20th is a day for people around the world to come together around the shared goal of happiness, lighting a warm glow in our hearts. Happiness isn't some distant destination -- it already exists in the small flowers blooming at your feet, or in a casual word shared with someone close to you. When you fill and care for your own heart, that calm energy ripples outward to those around you, becoming a force for a better world. Cherishing life's small joys is what guides your life toward something truly fresh and meaningful.
