Earth Hour 2026 | Cities Across India Go Dark As Earth Hour 2026 Observed

New Delhi's iconic India Gate, The Rashtrapati Bhavan and will go dark on Saturday night, between 8:30 pm and 9:30 pm IST, as part of Earth Hour 2026, a global environmental initiative encouraging people and institutions to switch off non-essential lights for one hour to raise awareness about climate change and environmental sustainability. Earth Hour this year marks the 20th anniversary of the global movement, observed under the theme "Give an Hour for Earth," highlighting collective action for our planet. Organised annually by the World Wildlife Fund (WWF), Earth Hour began in 2007 as a symbolic "lights-off" event in Sydney, Australia, and has since grown into one of the world's greatest grassroots environmental efforts, uniting millions of people, businesses, and monuments in more than 190 countries and territories.
