when is the union jack called the union jack
Union Jack The terms Union Jack and Union Flag are both historically correct for describing the de facto national flag of the United Kingdom. Whether the term Union Jack applies only when used as a jack flag on a ship is a modern matter of debate.[9]

Union Jack When the first flag representing Britain was introduced on the proclamation of King James I in 1606,[19] it became known simply as the "British flag" or the "flag of Britain". The royal proclamation gave no distinctive name to the new flag. The word "jack" was in use before 1600 to describe the maritime bow flag.[9] By 1627 a small Union Jack was commonly flown in this position. One theory goes that for some years it would have been called just the "Jack", or "Jack flag", or the "King's Jack", but by 1674, while formally referred to as "His Majesty's Jack", it was commonly called the "Union Jack", and this was officially acknowledged.[8]
Union Jack In 1606, James VI gave orders for a British flag to be created which bore the combined crosses of St. George and of St. Andrew. The result was the Union Jack, Jack being a shortening of Jacobus, the Latin version of James".
