International Day of Light?

Explanation:
International Day of Light is set on 16 May because that date marks the first successful operation of the laser in 1960, a milestone in the science and technology of light. The day honors how light and light-based technologies drive science, medicine, energy, communications, and sustainable development. Other May dates don’t correspond to this specific milestone or the official observance, so 16 May is the correct choice.
