International Youth Day (IYD) is an awareness day designated by the United Nations. The first IYD was on 12 August 2000. As with other political awareness days, such as Earth Day, the purpose of the day is to draw attention to a given set of cultural and legal issues surrounding an endangered demographic.

International Youth Day is on August 12 each year. It was designated by the United Nations in 1999 by the adoption of resolution 54/120.^[1]

The Sea Organization or Sea Org is an association of Scientologists established in 1968 by L. Ron Hubbard, the science fiction writer and founder of Scientology. Its members are found in the central management organizations of the Church of Scientology as well as in individual churches. Initially created at sea, maritime customs and traditions persist today even in the land-based branches of the organization.

Despite the name, the Sea Organization itself is not an actual incorporated entity, but rather what the Church refers to as a fraternal religious order. Sea Org members do not actually work for the Sea Org, but for the specific Church of Scientology where they are employed and receive their weekly allowance.
