St. Andrew's Day is the feast day of Saint Andrew. It is celebrated on November 30 in Scotland.

Saint Andrew is the patron saint of Scotland, and St. Andrew's Day (Scots: Saunt Andra's Day, Scottish Gaelic: Latha Naomh Anndra) is Scotland's official national day. In 2006, the Scottish Parliament designated St Andrew's Day as an official bank holiday.

Although most commonly associated with Scotland, Saint Andrew is also the patron saint of Greece, Romania, Russia, Ukraine and the Ecumenical Patriarchate of Constantinople.

In Germany, the feast day is celebrated as Andreasnacht ("St Andrew's Night"), in Austria with the custom of Andreasgebet ("St Andrew's Prayer"), and in Poland as Andrzejki ("Andrew's").

In 2006, the Scottish Parliament passed the St. Andrew's Day Bank Holiday (Scotland) Act 2007, which designated the Day as an official bank holiday. If 30 November falls on a weekend, the next Monday is a bank holiday instead.

The notion that the day should be an official bank holiday was first proposed by Dennis Canavan, Independent Member of the Scottish Parliament for Falkirk West in 2003. However, the Bill he introduced to the Parliament was initially rejected as the Executive did not support it. A compromise deal was reached whereby the holiday would not be an additional entitlement. Then First Minister, Jack McConnell, stated that he believed that employers and employees should mark the day with a holiday, but that this should be as a substitute for an existing local holiday, rather than an additional one.

Operation Sea Lion (German: Unternehmen Seelöwe) was Germany's plan to invade the United Kingdom during the Second World War, beginning in 1940. To have had any chance of success, however, the operation would have required air and naval supremacy over the English Channel. With the German defeat in the Battle of Britain, Sea Lion was postponed indefinitely on 17 September 1940 and never carried out.

By early November 1939, Adolf Hitler had decided on forcing a decision in the West by invading Belgium, the Netherlands and France. With the prospect of the Channel ports falling under Kriegsmarine (German Navy) control and attempting to anticipate the obvious next step that might entail, Grand Admiral (Großadmiral) Erich Raeder (head of the Kriegsmarine) instructed his operations officer, Kapitän Hans Jürgen Reinicke, to draw up a document examining "the possibility of troop landings in England should the future progress of the war make the problem arise." Reinicke spent five days on this study and set forth the following prerequisites:

St Andrew's is an association football stadium in the Bordesley district of Birmingham, England. It has been the home ground of Birmingham City Football Club for more than a century.

Constructed and opened in 1906 to replace the Muntz Street ground, which had become too small to meet the club's needs, the original St Andrew's could hold an estimated 75,000 spectators, housed in one grandstand and a large uncovered terrace. The attendance record, variously recorded as 66,844 or 67,341, was set at a 1939 FA Cup tie against Everton. During the Second World War, St Andrew's suffered bomb damage and the grandstand, housing a temporary fire station, burned down in an accidental fire. In the 1950s, the club replaced the stand and installed floodlights, and later erected a second small stand and roofed over the open terraces, but there were few further changes.

The ground became dilapidated: a boy was killed when a wall collapsed during rioting in the 1980s. When new owners took the club out of administration in 1993, they began a six-year redevelopment programme during which the ground was converted to an all-seater stadium to comply with the Taylor Report into safety at sports grounds, and all areas apart from the Main Stand were completely rebuilt. The seating capacity of the modern stadium is just over 30,000. It has function rooms suitable for business or social events and a club store selling Birmingham City merchandise. A 2004 proposal that the club should sell the ground and move into a multi-purpose City of Birmingham Stadium remains speculative.

Saint Andrew (Greek: Ἀνδρέας, Andreas; from the early 1st century—mid to late 1st century AD), called in the Orthodox tradition Prōtoklētos, or the First-called, is a Christian Apostle and the brother of Saint Peter. The name "Andrew" (Greek: manly, brave, from ἀνδρεία, Andreia, "manhood, valour"), like other Greek names, appears to have been common among the Jews, Christians, and other Hellenized peoples of the region. No Hebrew or Aramaic name is recorded for him. He is considered the founder and the first bishop of the Church of Byzantium and is consequently the patron saint of the Ecumenical Patriarchate of Constantinople.

The New Testament states that Andrew was the brother of Simon Peter, by which it is inferred that he was likewise a son of John, or Jonah.^{[Mt. 16:17] [Jn. 1:42]} He was born in Bethsaida on the Sea of Galilee.^[Jn. 1:44] Both he and his brother Peter were fishermen by trade, hence the tradition that Jesus called them to be his disciples by saying that he will make them "fishers of men" (Greek: ἁλιεῖς ἀνθρώπων, halieĩs anthrōpōn). At the beginning of Jesus' public life, they were said to have occupied the same house at Capernaum.^{[Mk. 1:21-29]}
