Earth Overshoot Day - Annual Date Varies

Earth Overshoot Day is hosted and calculated by the Global Footprint Network. The first Overshoot day in 1987 was calculated to be October 23rd. In 2022, that date was pushed back to July 28th.

Earth Hour - Annually at the End of March
Starting as a symbolic lights-out event in Sydney, Australia, in 2007, Earth Hour is one of the world's largest grassroots movements for the environment, inspiring millions of people to take action for our planet and nature. Every year, millions of people, businesses, and landmarks switch off their lights and set aside an hour to host events from 8:30 - 9:30 pm (local time) and make noise for the Earth Hour movement. This year, speak up for why nature matters to you and put action at the center of international conversations! For more resources, visit the WWF Earth Hour Website including activities for schools.
