St Andrews Day is on 30 November. On this day, Scots all around the world celebrate their national day. The Scottish flag is the cross of St. Andrew, also known as the Saltire. It is said to be one of the oldest national flags of any country, dating back at least to the 12th century.
Saint Andrew is the patron saint of Scotland, Greece and Russia and was Christ's first disciple.
St. Andrew was one of the Twelve Apostles (disciples of Jesus) and brother of Simon Peter (Saint Peter). He was a fisherman by trade, who lived in Galilee (in present-day Israel.)
