- This timeline is not exact but it should give everyone a good idea of when each game and important events happened. This should help minimize the number of mistakes made in histories due to a misunderstanding of the timelines.

Year 0 - Xehanort takes Ventus to the Destiny Islands with the intentions of allowing him to die. Instead Ven's heart connects with the heart of the newborn Sora. Xehanort takes Ventus to the Land of Departure and leaves him with Master Eraqus instead.

Year 4 - The events of Birth by Sleep happen over the course of a week. The Land of Departure is turned into Castle Oblivion in an attempt to hide and protect Ven's body.

Year 5 - By now the first 8 members of Organization XIII have been 'made'. Worlds have started falling to the darkness of the heartless and Traverse Town was born in response to this. All citizens of the Radiant Gardens were evacuated under the eye of Cid to Traverse Town.

Year 14 - The events of Kingdom Hearts happen over the course of a month. The nobodies Namine and Roxas are born. Kairi's heart is returned and she is sent back to the Islands after they are recovered. All worlds that were swallowed whole by the heartless have been restored, though some still sleep. Leon oversees the efforts to bring all citizens back to the Radiant Gardens and become restoration efforts.

Year 14.5 - The event of Days and Chain of Memories occur. Xion is born and dies. Roxas rebels against the Organization but is captured by Riku. Sora's memories are pulled apart by Namine and is placed into a year-long sleep to allow her to mend her mistake.

Year 15.5 - The events of ReCoded occur. Mickey realizes that he needs to test Sora and Riku before he can tell them the full truth of their situation. Sora and Riku are thrown into their Master of Mastery Exam where they must awaken several worlds that were unable to fully 'wake up' after being restored. Xehanort uses this as an attempt to split the two apart and to weaken Sora's heart and resolve, thus turning him into a vessel for darkness. The Nobodies of Organization XIII reawaken as their Somebodies and Lea is granted a keyblade before helping to save Sora from Xehanort. Riku dives into Sora's heart to cleanse the darkness from it and discovers that Sora's heart was protected the entire time by Ventus' armor. Riku is granted the title of Master and is told to bring Kairi in to begin her training.
