International Day of Light

International Day of Light History

International Day of Light highlights 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.

Initially endorsed in 2017, 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, International Day of Light gives 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. International Day of Light is celebrated each year on 16th May.
