The International Day of Light will provide an annual focal point for the continued appreciation of the central role that light plays in the lives of the citizens of the world in areas of science, culture and art, education, sustainable development, and in fields as diverse as medicine, communications and energy. Following the highly successful International Year of Light and Light-based Technologies 2015, the broad theme of light will allow many different sectors of society to participate in activities around the world around May 16th to raise awareness of science and technology, art and culture, and their importance in achieving the goals of UNESCO — education, equality and peace.
The International Day of Light will be proclaimed at the General Conference of UNESCO in November 2017 and the first celebration will take place on 16 May 2018.
The full website will be online in November 2017. In the meantime, you can begin to plan activities for the 16 May 2018 by reviewing the wide variety of events that took place throughout the International Year of Light in 2015.
