a journal or account of daily transactions; a diary.

In Astronomy, it denotes an account of the daily state or positions of the planets; that is, a table, or a collection of tables, exhibiting the places of the planets each day at noon. It is from these tables that the eclipses, conjunctions, and other aspects of the planets, are calculated. The principal works of this kind are our own Nautical Almanack, the Berlin Jahrbuch, and the French Connaissance des Ephédiens Temps. See Astronomy.
