The Connaissance des temps is an official astronomical yearly publication in France.

History[edit]

Connaissance des temps is the oldest such publication in the world, published without interruption since 1679 (originally named La Connaissance des Temps ou calendrier et éphémérides du lever & coucher du Soleil, de la Lune & des autres planètes), when the astronomer Jean Picard (1620–1682) obtained from the King the right to create the journal. Notable authors were:

Among the other prestigious ephemerides, The Nautical Almanac was only established in 1767 and the Berliner Astronomisches Jahrbuch in 1776.

Contents[edit]

The volumes of the Connaissance des temps had two parts:

  • a section of ephemerides, containing various tables
  • articles giving a deeper coverage of various topics, often written by famous astronomers
