The Nautical Almanac
The free online Nautical Almanac
The world's most complete source of free celestial navigation information



The Nautical Almanacs and Sun Almanacs listed at the top of our site were created or derived from a program written by the great Norwegian sailor Enno Rodegerdts.  Without his work this site wouldn't exist.
