September 18 is a valuable date for competitive-examination students because it connects labour rights, Latin American history, modern journalism, East Asian history, the United Nations, space exploration, sustainability and India's technology and artisan sectors.
The United Nations observes September 18 as International Equal Pay Day. The day promotes the principle of equal pay for work of equal value and is linked with wider goals of gender equality, decent work and inclusive economic development.
The UN General Assembly established International Equal Pay Day through Resolution A/RES/74/142 in 2019 and decided that the observance would begin in 2020.
In world history, September 18, 1810 marks the formation of Chile's First National Government Junta in Santiago. Although Chile's formal proclamation of independence came later in 1818, September 18 became the country's principal national celebration.
