The Wikipedia article of the day for January 1, 2019 is Die Zeit, die Tag und Jahre macht, BWV 134a.Die Zeit, die Tag und Jahre macht (Time, which day and year doth make), BWV 134a, is a secular cantata by Johann Sebastian Bach for a celebration of New Year's Day in 1719 at the court of Leopold, Prince of Anhalt-Köthen (hall in the palace pictured). The libretto by the author Christian Friedrich Hunold portrays a dialogue between two allegorical figures, Time (representing the past) and Divine Providence (the future). Bach set the words to eight movements consisting of alternating recitatives and arias, culminating in a choral finale. Most movements are duets for alto and tenor, supported by a Baroque instrumental ensemble of two oboes, strings and continuo. The character of the music is close to Baroque opera, including its French dances. In Leipzig in 1724, Bach used this secular work as the basis for a church cantata for the Third Day of Easter, omitting two movements and changing only the text.
