What it is Filled

July 12, day 193 (day 194 in leap years) of the year in the Gregorian calendar, with 172 days remaining in both common and leap years. July 12 is Independence Day in Sao Tome and Principe marking 1975 and in Kiribati marking 1979, and in Northern Ireland the Twelfth, when the Orange Order commemorates the 1690 Battle of the Boyne with parades that some communities regard as contentious; in 2022 the full initial set of images and spectra from the James Webb Space Telescope was released on this date, following the release of its first full-colour image on July 11.

Only with a human decision

May

  • List observances on July 12 with the country or community that holds each one.

Moral aspects Filled
