Days Until World UFO Day

About World UFO Day

July 2 is popularly associated with World UFO Day, an informal, non-governmental observance rather than a UN-designated day, commonly linked by UFO enthusiasts to the Roswell incident of 1947, though some sources instead mark an alternative UFO-related observance date of June 24.

Unlike the UN-system observances on this list, this date's significance rests on popular and enthusiast tradition rather than an official international body's designation.

The Roswell incident the informal observance is often linked to involved a US military balloon-borne surveillance device, according to the US Air Force's later official explanation, though the case remains a fixture of American UFO folklore regardless.

Roswell's annual UFO festival, held around the anniversary of the 1947 incident, has become a significant local tourism draw for the small New Mexico town, independent of the informally observed July 2 date itself.
