International Day of Light

The International Day of Light (IDL) is a worldwide celebration that highlights the importance of light and its various applications in science, culture, art, education, and sustainable development. The annual observance aims to raise awareness about light-based technologies, promote sustainable practices, and improve quality of life in numerous sectors such as energy, agriculture, and healthcare. This global initiative intends to illuminate the vital role of light in our daily lives and inspire future generations to recognize its transformative power and endless possibilities.

Launched by UNESCO in 2015 during the International Year of Light and Light-based Technologies, the International Day of Light has been celebrated annually on 16 May since 2018. This day serves as an important platform for stakeholders such as scientists, industry professionals, artists, and educators to exchange ideas, share knowledge, and foster collaborations. South Africa, with its wealth of scientific and technological capabilities, actively participates in this initiative, contributing to local and global discussions about light and its potential to drive development and innovation.

Marking the anniversary of the first successful operation of the laser by Theodore Maiman in 1960, the International Day of Light provides an exciting opportunity for South Africa to explore and showcase its own achievements, discoveries, and advancements in the field of light science and technology. Be sure to join your fellow South Africans and the global community in celebrating this illuminating day on 16 May every year.
