The 39th Session of the UNESCO General Conference has proclaimed the date of May 16th as the International Day of Light. The proclamation of this annual International Day enables global appreciation of the central role that light and light-based technologies play in the lives of the citizens of the world in areas of science, technology, culture, education, and sustainable development.
The International Day of Light is an enduring follow-up to UNESCO’s International Year of Light in 2015 that reached over 100 million people in over 140 countries.
The International Year of Light and Light-based Technologies 2015 built many new bridges between science and culture, and forged new links between decision makers, industry leaders, scientists, non-governmental organizations and the public at large. An International Day of Light responds to the critical need for improved dialogue between citizens, scientists, and policy-makers in order to pursue sustainability with a help of lighting.
