The original equinoctial Earth Day is celebrated in most countries on the vernal equinox to mark the precise moment that spring begins in the Northern Hemisphere and autumn in the Southern Hemisphere. At this global moment, night and day are equal length anywhere on Earth. At the South Pole, the sun sets, bringing an end to the six-month-long day, while at the North Pole, the sun rises, ending six months of continuous darkness. Anyone standing on the equator at noon will not cast a shadow. Earth Day is a day of equilibrium when differences are forgotten and nature's renewal is celebrated by all.
This annual event marks the beginning of Earth Day which has been traditionally observed with the ringing of bells. Earth Day was created to remind us of our shared responsibility to protect the planet. The United Nations celebrates Earth Day each year on the vernal equinox (around March 21). On February 26, 1971, UN Secretary-General U Thant signed a proclamation to that effect: 'May there only be peaceful and cheerful Earth Days to come for our beautiful Spaceship Earth as it continues to spin and circle in frigid space with its warm and fragile cargo of animate life.'
