International Day of Light

The International Day of Light is a global celebration of the unique role that light plays in our lives, its transformative nature, its impact on science, culture, and arts, and ways in which it drives economic growth and sustainable development. Every year on 16th May, countries around the world celebrate the power of light and its ability to inspire breakthroughs in fields as diverse as medicine, communications, energy, and agriculture. The Observance is a time when we recognise the countless ways in which light enriches our lives and encourages the sharing of knowledge, resources, and experiences that can help build a more enlightened world.

Initially endorsed in 2017, the International Day of Light is based on the highly successful International Year of Light and Light-based Technologies celebrated in 2015, which saw more than 13,000 events in 147 countries take place. This global initiative was the catalyst that led to the proclamation of the annual event by the United Nations General Assembly. The day is commemorated with events focused on public outreach, art installations, academic conferences, and educational resources, further advancing people's understanding of the importance of light technology and its necessity in creating a better, more sustainable future.

For New Zealanders, embracing the International Day of Light is an opportunity to learn about the many ways light impacts our lives and our environment. From solar energy to the magical beauty of the Southern Lights, Aotearoa is a land where light plays a crucial part in shaping our world. Mark your calendars and join the global community in celebrating the International Day of Light every 16th May, and become a part of the conversation on the wonders and potential of light.
