Definition
-
A nautical almanac is a specialized publication commonly used by sailors, navigators, and astronomers as a comprehensive reference guide for celestial navigation and timekeeping at sea. It is an indispensable tool that provides essential astronomical information and data to determine positions and calculate celestial phenomena.
Usually published annually, a nautical almanac features astronomical tables, diagrams, and charts that enable navigators to accurately visualize and interpret celestial bodies in relation to their positions on Earth. It includes accurate predictions of the rising and setting of the Sun, Moon, planets, and stars, along with their azimuth and altitude angles, allowing sailors to calculate precise navigational bearings and establish their location on the open sea.
Furthermore, a nautical almanac contains information about lunar phases, eclipses, tides, and other celestial phenomena that influence navigation. It also incorporates various correction tables to account for factors such as atmospheric refraction, parallax, and deviations from standard timekeeping due to Earth's irregular rotation.
In addition to celestial navigation, the nautical almanac is also used by astronomers for observations, astrophysical calculations, and research purposes. Its accuracy and reliability make it an essential reference for celestial positioning, timekeeping, and astronomical calculations both on land and at sea.
Overall, a nautical almanac serves as a vital resource, providing the necessary data and knowledge to ensure safe and accurate navigation by sailors and astronomers alike.

Etymology of NAUTICAL ALMANAC
The word "nautical" originates from the Latin word "nauticus", which means "pertaining to ships or sailors". It ultimately derives from the Greek word "naútikos". The term "almanac", on the other hand, comes from the Arabic word "al-manākh", which means "calendar" or "annual table". Through various languages, such as Latin and Old French, the term entered English in the 14th century. Thus, the phrase "nautical almanac" combines the Latin and Arabic roots to refer to a publication or table with information concerning navigation, specifically for sailors or those related to ships.
