When Is Earth Day 2025. In 2025 earth day is on april 22nd (tuesday). In october 1969, at the national unesco conference in san francisco, john mcconnell proposed a global holiday to celebrate earth's life and beauty and to advance peace.

This is why earth day’s theme for 2025, our power, our planet, is perhaps our most important theme ever. It is a day held to demonstrate and promote environmental awareness and calls for the protection of our planet.
