Suzumiya Haruhi no Yuuutsu (2009) EP13 エンドレスエイト

Like the previous episode, Kyon's easy going summer vacation is interrupted as the group is taken on a whirlwind tour of summer activities. However, Kyon is wracked by a sense of déjà vu. Itsuki is likewise troubled, while Yuki seems even more detached than usual. They finally figure out that Haruhi has put the last two weeks of August into an infinite loop because she refuses to let summer end. They find out that the loop has repeated 15,498 times, but none of them can devise anything to stop the cycle from repeating. Though the repeating cycle changed during the 2391 and 11054th times when the SOS Brigade did not attend the Bon Odori festival, 437 times when they did not go goldfish catching and 9025 times when they did various part time jobs, which is divided into six different jobs. Upon their last meeting in a restaurant on August 30, Kyon calls out after Haruhi in a last-ditch attempt to stop her from leaving, but fails to think of anything he can do, and she leaves. As the last day of vacation arrives, Kyon, resigned to the loop repeating itself, goes to bed without finishing his summer homework.
