As first pointed out by Swiftie @tayslotsversion on X, the order of Swift's eras on the concert setlist seems to correspond with the months she announces her 'Taylor's Version' albums. For instance, Fearless is the show's second act, and she confirmed the Fearless (TV) release date in February 2021.
Since the Eras Tour kicked off in March 2023, Swift has revealed her 'Taylor's Version' albums at her shows, announcing Speak Now (TV) onstage in Nashville and in Los Angeles.
