2012–13 LEB Oro season

The champion of the regular season would be promoted to Liga ACB.

Like many other leagues in continental Europe, the Liga LEB takes a winter break once each team has played half its schedule.

One feature of the league that may be unusual to North American observers is that the two halves of the season are played in the same order—that is, the order of each team's first-half fixtures is repeated in the second half of the season, with the only difference being the arenas used.

This procedure is typical in Europe; it is also used by La Liga in football.

At the final of the season: New teams in the league: Teams that left the league: (C) = Copa Príncipe de Asturias champion At the half of the league, the two first teams in the table play the Copa Príncipe de Asturias at home of the winner of the first half season (17th round).
