Earth Day has always been a day that acknowledges our planet, which provides for us, and ways we can protect and preserve its beauty. That being said, here's everything you should know about Earth Day 2025, and its 55th annual celebration. Earth Day falls on April 22 every year. This year, it falls on a Tuesday.

Earth Day has its roots in growing concern over pollution in the 1960s, when author Rachel Carson's 1962 book “Silent Spring,” about the pesticide DDT and its damaging effects on the food chain, hit bestseller lists and raised awareness about nature's delicate balance.
