This is the chronological timeline of "K-ON!"
But, after the release of "K-ON! Shuffle", it seems to have been changed to an unknown timeline (only known to be somewhere in the current era), this timeline is adapted to the original run, which covers from 1984 to 2011, and will be updated once Kakifly announces the time span of the Shuffle adaptation.
