A flag day is a flag-related holiday—either a day designated for flying a certain flag (such as a national flag), or a day set aside to celebrate a historical event such as a nation's adoption of its flag.

Flag days are usually codified in national statutes, however, in some countries a decree by the head of state can also order a flag day. The statute or decree may specify locations where flags are flown and how are they flown (for example, at full- or half-staff); alternatively, custom may prevail.^[1]

Study Technology, or Study Tech, is a methodology for learning developed by L. Ron Hubbard, founder of the Church of Scientology. Hubbard's "Study Technology" is used by Church of Scientology members as part of their training, and is also promoted outside the church by a church-affiliated corporation known as Applied Scholastics, which presents Study Tech as a universally applicable method to enhance the comprehension of any student, studying any topic.

It was publicly stated by Hubbard that Study Tech is directly affiliated with Scientology. He wrote in a policy letter that "Study Tech is our primary bridge to Society."^[1] All Study Tech books include a two-page biography of Hubbard which does not mention his role in creating Scientology.^[2]
