How many days until Earth Hour?

About Earth Hour

Earth Hour is a global environmental observance in which individuals, businesses, and landmarks around the world are encouraged to switch off non-essential electric lighting for one hour in the evening, as a symbolic gesture drawing attention to climate change and energy consumption. The event is organized annually by an international environmental organization, and its specific date is set independently each year rather than following a fixed calendar formula, though it consistently falls on a Saturday evening in the second half of March, with the exact date announced by the organizing body ahead of the event; because the date is set independently each year, reliable exact dates for years beyond the next one or two cannot be published with confidence until officially confirmed. The event began in a single city, Sydney, Australia, in 2007 as a localized initiative before rapidly expanding into a genuinely global observance within just a few years, eventually involving landmark buildings, monuments, and cities switching off lighting simultaneously across many time zones, coordinated so that the hour rolls around the globe rather than occurring at a single fixed universal time. Participation ranges from individual households turning off household lighting for the hour to major national governments and corporations coordinating large-scale lighting shutdowns at prominent public buildings and landmarks, giving the event both a personal, grassroots dimension and a highly visible, large-scale symbolic one. A common misconception is assuming Earth Hour meaningfully reduces global energy consumption in a measurable way; its organizers have generally framed the event primarily as a symbolic, awareness-raising gesture rather than a serious energy conservation measure, given the brief duration and voluntary, partial nature of participation.
