The Global Season is the season number used when counting from the beginning of Hattrick's existence. This number is also the same as the Sverige season, since Sverige has been in the game since its beginning. The leagues Argentina, Danmark, Deutschland, England, France, Italia, México, Suomi, and USA share the global season as well, although they are not as old as Sverige. After these leagues were created, all other leagues were given their own season number starting at 1.
The global season is currently season 71.
Any global season can be calculated by adding 16-week intervals (one Hattrick season) to the date 1997-05-25.
