International Day of Light

International Day of Light is an annual event that aims to raise awareness about the critical role of light-based technologies, the importance of light in the fields of science, culture, and society, and how it contributes to a sustainable future. This global initiative focuses on illuminating the considerable potential of using light technology for the betterment of humankind and in tackling challenges such as climate change, health, and energy consumption. The event goes beyond mere celebration - it seeks to inspire reflection, dialogue, and collaboration around the countless applications of light in our world.

Launched in 2018 by UNESCO (United Nations Educational, Scientific and Cultural Organization), International Day of Light builds on the success of the International Year of Light, held in 2015. It was during this year that more than 13,000 events spread across 147 countries showcased the numerous practical applications and incredible potential of light-based technologies. The International Year of Light's impact extended beyond its timeframe, as initiatives such as the 1001 Inventions & the World of Ibn Al-Haytham campaign, designed to promote intercultural dialogue, continued to gain global attention.

In Canada, educational institutions, museums, and various organizations host an array of events, workshops, and exhibits to mark International Day of Light. Fostering knowledge, engagement, and collaboration, the celebrations highlight the many ways in which light technology touches our lives - from energy efficiency and telecommunications to agriculture and medicine. At these events, participants can expect to learn about the growing opportunities for innovation and development, powered by light technologies. International Day of Light is celebrated annually on May 16th, marking the anniversary of the first successful operation of the laser in 1960 by physicist and engineer Theodore Maiman.
