Duanwu Festival, also known as Dragon Boat Festival and the Double Fifth, is a traditional and statutory holiday originating in China and associated with a number of East Asian and Southeast Asian societies. In Mandarin, it is known by the name Duānwǔ Jié; in Hong Kong and Macau, by the Cantonese name Tuen Ng Festival; in Hokkien-speaking areas, by the names Gō͘-go̍eh-cheh/Gō͘-ge̍h-choeh (五月節) and Gō͘-ji̍t-cheh/Gō͘-ji̍t-choeh (五日節). In 2008, it was recognised as a public holiday in mainland China for the first time since the 1940s.^[1][2] The festival has also long been celebrated in Taiwan, Singapore, and Malaysia. Equivalent and related festivals in Asia include the Kodomo no hi in Japan, Dano in Korea, and Tết Đoan Ngọ in Vietnam.

The festival occurs on the 5th day of the 5th month of the lunar calendar on which the Chinese calendar is based. This is the source of the alternative name of Double Fifth.^[3] In 2011, this fell on June 6. The focus of the celebrations includes eating the rice dumpling zongzi (Chinese: 粽子; pinyin: zòngzi)^[4], drinking realgar wine xionghuangjiu (Chinese: 雄黃酒; pinyin: Xiónghuángjiǔ), and racing dragon boats.

Juneteenth, also known as Freedom Day or Emancipation Day, is a holiday in the United States honoring African American heritage by commemorating the announcement of the abolition of slavery in the U.S. State of Texas in 1865. Celebrated on June 19, the term is a portmanteau of June and nineteenth,^[1] and is recognized as a state holiday or state holiday observance in 41 states of the United States.^[2][3]

The state of Texas is widely considered the first U.S. state to begin Juneteenth celebrations with informal observances taking place for over a century; it has been an official state holiday since 1890. It is considered a "partial staffing holiday", meaning that state offices do not close, but some employees will be using a floating holiday to take the day off. Schools are not closed, but most public schools in Texas are already into summer vacation by June 19th. Its observance has spread to many other states, with a few celebrations even taking place in other countries.^[4][5]

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]

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]
