International Day of Light History

The International Day of Light (IDL) is a global annual observance that aims to cherish and honour the pivotal role of light in numerous facets of our lives - ranging from scientific discoveries, to cultural and artistic expressions, and its importance for sustainable development. Celebrated worldwide, IDL endeavors to raise awareness of the ways in which optical technologies, such as photonics and advanced imaging techniques, contribute to advancements in fields like medicine, communications, and energy, while also highlighting light’s sheer beauty and its embodiment of hope and inspiration.

Established by UNESCO in 2017, the International Day of Light commemorates the anniversary of the first successful operation of a laser by engineer and physicist Theodore Maiman. IDL's main objective is to encourage global appreciation for the vital role of light, and its associated technologies, in areas such as education, art, culture, and the achievement of the United Nations’ Sustainable Development Goals. By engaging various sectors of society, including scientific communities, industry, educational institutions, and cultural organizations, IDL fosters dialogue and collaboration that underscores the importance of light's impact on every aspect of our lives.

Held annually on May 16th, the International Day of Light reiterates the power and significance of light in various spheres of human endeavor, fostering a deep-rooted connection between people and the unifying power of light. In Australia, numerous events are organized, dedicated to celebrating the diverse and incredible ways in which light influences our world, providing the perfect opportunity for everyone to share in the marvel that is light.
