Nautical almanac
A nautical almanac is a publication describing the positions and movements of celestial bodies, including the sun, moon, planets, and stars. In Great Britain a nautical almanac has been published annually by the HM Nautical Almanac Office, ever since the first edition was published in 1767. The nautical almanac is usually used together with a sextant and a chronometer for celestial navigation while at sea.
