What is the birthdate of this King of Denmark and Norway, of whom Mogens Gaye was the Royal councillor?

Mogens Gøye
Mogens Gøye (surname also spelled Gøje or Gjøe) (ca. 1470 – 6 April 1544) was a Danish statesman and Steward of the Realm, whose enormous wealth earned him the derogatory nickname "the King of Northern Jutland".
 Gøye was the Royal councillor of Danish Kings John I, the feuding Christian II and Frederick I, and Christian III.
 He was a key supporter of the Reformation in Denmark-Norway and Holstein.
 Often lauded by elder Danish historians as a knightly, social liberal upper-class idealist, Gøye is today viewed as a realist statesman understanding the need of a government and a moderate political attitude of the nobility.
Frederick I of Denmark
Frederick I (7 October 1471 – 10 April 1533) was the King of Denmark and Norway.
 His name is also spelled "Friedrich" in German, "Frederik" in Danish and Norwegian and "Fredrik" in Swedish.
 He was the penultimate Roman Catholic monarch to reign over Denmark, when subsequent monarchs embraced Lutheranism after the Protestant Reformation.
 As King of Norway, Frederick is most remarkable in never having visited the country and was never being crowned King of Norway.
 Therefore he was styled "King of Denmark, the Vends and the Goths, elected King of Norway".
