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
