ISO week dateThe ISO week date system is effectively a leap week calendar system that is part of the ISO 8601 date and time standard issued by the International Organization for Standardization (ISO) since 1988 (last revised in 2019) and, before that, it was defined in ISO (R) 2015 since 1971. It is used (mainly) in government and business for fiscal years, as well as in timekeeping. This was previously known as "Industrial date coding". The system specifies a week year atop the Gregorian calendar by defining a notation for ordinal weeks of the year.
Mortal sinA mortal sin (peccatum mortale), in Catholic theology, is a gravely sinful act which can lead to damnation if a person does not repent of the sin before death. It is alternatively called deadly, grave, and serious. A sin is considered to be "mortal" when its quality is such that it leads to a separation of that person from God's saving grace. Three conditions must together be met for a sin to be mortal: "Mortal sin is sin whose object is grave matter and which is also committed with full knowledge and deliberate consent.
Jean GiraudJean Henri Gaston Giraud (ʒiʁo; 8 May 1938 – 10 March 2012) was a French artist, cartoonist and writer who worked in the Franco-Belgian bandes dessinées (BD) tradition. Giraud garnered worldwide acclaim predominantly under the pseudonym Mœbius (ˈmoʊbiəs; məbjys) for his fantasy/science-fiction work, and to a slightly lesser extent as Gir (ʒiʁ), which he used for the Blueberry series and his other Western themed work. Esteemed by Federico Fellini, Stan Lee, and Hayao Miyazaki, among others, he has been described as the most influential bande dessinée artist after Hergé.
