Shining a Light on May 16, 2025
Each year on May 16, the world comes together to celebrate the International Day of Light, a day dedicated to the wonders and significance of light in our daily lives. Light is essential to humanity in more ways than we can imagine — from powering our daily routines to inspiring breakthroughs in science, art, and culture. But how did this luminous celebration come about, and why is it so important?
The History of the International Day of Light
The International Day of Light was first proclaimed by UNESCO in 2017, and it has been celebrated annually since May 16, 2018. The date, May 16, was chosen to commemorate the anniversary of the first successful operation of the laser in 1960, a groundbreaking achievement by physicist Theodore Maiman. This invention paved the way for countless innovations in fields ranging from medicine to telecommunications.
The day aims to highlight the crucial role light plays in addressing challenges in sustainable development, education, and health while recognizing its influence on culture and art throughout history.
Why Celebrate Light?
Light is more than what meets the eye. It is a symbol of knowledge, innovation, and progress.
