Significance of International Day of Light

Light plays an important role in not only our lives but also in the field of science, culture and art, education, and sustainable development. More than that, light also finds its application in fields of medicine, communications and energy. On the most basic level, light is responsible for photosynthesis and is the origin of life as well. To celebrate all that light does and can do for us, International Day of Light began to be celebrated.

Information about International day of living together in peace

Study of light has led to finding medical advances in diagnostics technology and treatments that turned out to be a lifesaving discovery. Alternative energy sources, light-speed internet and many more discoveries are there that revolutionized society which was only possible with the development of light-based technology.

History behind International Day of Light

To raise awareness around the globe regarding the achievements of light science and its numerous applications, the United Nations observe the International Year of Light and Light-based Technologies in 2015 (IYL 2015). The event was a great success and following it, the countries of Ghana, Mexico, New Zealand and Russia put forward a resolution before the UNESCO Executive Board supporting to observe International Day of Light annually. At the Board’s 200th session the resolution was adopted on September 19, 2016 at the UNESCO HQ in Paris, France.
