Johann Sebastian Bach (1685-1750) left us a wide collection of cantatas, written for celebratory days of the liturgical calendar or other special celebrations.
This website follows that calendar, based on the liturgical rhythm and the dates of those celebrations, presenting the cantata(s) for the day and playlists with those cantatas on five major audio streaming services: Spotify, Apple Music, Tidal, Qobuz and Deezer.
