cantata cycle overlap, and the two designations are often used interchangeably in scholarly literature. Otherwise the cycle is described as breaking off after Palm Sunday or Easter 1725. There are some cantatas that belong to one of both cycles, but not to the other, for instance the chorale cantata for Trinity 1727 replaces the Trinity cantata of the second cycle composed in 1725. Also, some cantatas traditionally seen as belonging to the chorale cantata cycle are not chorale cantatas in a strict sense, for instance the cantata for the Sunday between New Year and Epiphany added to the chorale cantata cycle in 1727. Neither the second cantata cycle, nor the chorale cantata cycle are complete annual cycles as extant. Even a merging of both cycles into one, with some occasions having two cantatas, which hardly can be seen as an intention of the composer, would still be missing a few cantatas (e.g. for Easter 3 and Trinity XXVI). Chorale cantatas composed as part of the second annual cycle (Trinity I 1724 to Palm Sunday 1725) All extant church cantatas Bach composed for occasions from 11 June 1724 (Trinity I) to 25March 1725 (Palm Sunday) are chorale cantatas. As such these cantatas have consecutive "K" numbers in the chronological Zwang catalogue for Bach's cantatas published in 1982. In the Zwang catalogue the cantata for Reformation Day Ein feste Burg ist unser Gott, BWV 80, is inserted between the cantatas for Trinity XXI and XII, as a cantata premiered in 1724. More recently, this cantata is, however, no longer considered to have been composed in 1724. Bach's last newly composed chorale cantata in his second year in Leipzig was , for the feast of the Annunciation on 25March, which fell on Palm Sunday in 1725. Of the chorale cantatas composed up to Palm Sunday 1725 only K77, 84, 89, 95, 96 and 109 (BWV135, 113, 130, 80, 115 and 111) were not included in the chorale cantata cycle that was still extant in Leipzig in 1830. Sundays after Trinity In 1724 the period of the Sundays after Trinity included St. John's Day (24June), Visitation (2July, that year coinciding with Trinity IV), St. Michael's Day (29September) and Reformation Day (31October). That year the last Sunday after Trinity, that is the last Sunday before Advent, was Trinity XXV: Trinity I, 11 June 1724: O Ewigkeit, du Donnerwort, BWV 20 (K 74). Trinity II, 18
