Are you saying the league is closed when it should be open according to its schedule? If so that sounds odd. If you’re asking about why there’s a schedule:

From Turn 10’s announcement:
"Leagues are a brand new multiplayer feature for Forza 6, one that lets players compete in thrilling multiplayer races that are scheduled and based around each player’s skill level and temperament. The cornerstones of Leagues are its scheduled race lobbies. All League lobbies run on a schedule and will be open in the game during specific times each day. For example, there might be a B-Class League lobby that will be open for four hours per day for a full week; after which, it will be replaced with a new League lobby featuring different cars and/or tracks. While a League’s daily open window may vary from League to League, we are designing these windows to be open to allow the most players within different time zones.
During an open window, players can join a League Lobby and compete against one another in that lobby’s playlist. After each race, players will earn points based on their performance (what position they placed in, as well as the number of higher-skilled players they beat). As long as a League window is open, players can continue to play in that lobby and earn points; these points will accumulate on that League’s leaderboard for the duration of the League. Once a scheduled League has closed down, players will earn credits based on their final position on the League’s overall leaderboard.
