Week

A week is a time unit equal to seven days. It is the standard time period used for cycles of work days and rest days in most parts of the world, mostly alongside (but not strictly part of) the Gregorian calendar.

The days of the week were named in different languages after classical planets, various deities (example: Thursday – Thor's day, a variation after Jupiter's day from Roman times) and heavenly bodies (example: Sunday – Sun's day) and other sources. In English, the names are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.

ISO 8601 includes the ISO week date system, a numbering system for weeks within a given year – each week begins on a Monday and is associated with the year that contains that week's Thursday (so that if a year starts in a long weekend Friday–Sunday, week number one of the year will start after that).

The term "week" is sometimes expanded to refer to other time units comprising a few days, such as the nundinal cycle of the ancient Roman calendar.

League of Legends Championship Series

The League of Legends Championship Series (LCS), formerly known as the Riot Championship Series, is the name of two professional League of Legends eSports leagues run by Riot Games. Twenty teams compete in two separate competitions in North America and Europe, with ten teams per continent. Each annual season of play is divided into two splits, spring and summer, both consisting of nine weeks of round-robin tournament play, which then conclude with play-off tournaments between the top six teams from each region. At the end of the season, the highest placing three teams in each league qualify for the annual League of Legends World Championship.

The LCS represents the highest level of League of Legends play in Europe and North America. The LCS has a promotion and relegation system; the bottom teams in the LCS from each split compete with the top teams from the Challenger Series (CS) to compete for spots in the next split of the LCS. The Challenger Series in each continent is composed of six teams: three teams which failed to advance in the previous promotion tournament, one team from the previous CS split, and the top two teams from ranked ladder play in the respective public League of Legends online game server.

Last Week Tonight with John Oliver

Last Week Tonight with John Oliver, often abridged as Last Week Tonight, is an American late-night talk and news satire television program airing on Sundays on HBO in the United States and HBO Canada, and on Mondays (originally Tuesdays) on Sky Atlantic in the United Kingdom. The half-hour long show premiered on Sunday, April 27, 2014, and is hosted by comedian John Oliver. Last Week Tonight shares some similarities with Comedy Central's The Daily Show with Jon Stewart, where Oliver was previously featured as a correspondent and fill-in host, as it takes a satirical look at news, politics and current events on a weekly basis.

Oliver has said that he has full creative freedom, including free rein to criticize corporations. His initial contract with HBO was for two years with an option for extension. In February 2015, it was announced that the show has been renewed for two additional seasons of 35 episodes each. Oliver and HBO programming president Michael Lombardo have discussed extending the show from half an hour to a full hour and airing more than once a week after Oliver "gets his feet under him".
