World Ozone Day

World Ozone Day is observed on 16/09/2026 in India. It commemorates the 1987 signing of the Montreal Protocol to phase out ozone-depleting substances. The day is typically marked by awareness drives at schools and environmental ministries.

For schools, offices and government bodies, this date often means half-day schedules, special assemblies, or public holidays depending on the state — worth checking your local calendar if you're planning around it.
