Leipzig observed "tempus clausum", quiet time, in Advent and Lent, when no cantatas were performed. All cantatas for these occasions date from Bach's earlier time. He reworked some cantatas from this period for different occasions. The high holidays Christmas, Easter and Pentecost were each celebrated on three days. Additionally, feasts were celebrated on fixed dates, the feasts of Purification of Mary (Mariae Reinigung, 2 February), Annunciation (Mariae Verkündigung, 25 March) and Visitation (Mariae Heimsuchung, 2 July), and the Saint's days of St. John the Baptist (Johannis, 24 June), St. Michael (Michaelis, 29 September), St. Stephen (Stephanus, 26 December, the second day of Christmas) and St. John the Evangelist (Johannes, 27 December, the third day of Christmas). Further feasts on fixed days were New Year's Day (Neujahr, 1 January), Epiphany (Epiphanias, 6 January) and Reformation Day (Reformationsfest, 31 October). Sacred cantatas were also performed for the inauguration of a new city council (Ratswechsel, in Leipzig in August), consecration of church and organ, weddings, confession, funerals, and functions of the University of Leipzig.
