An almanac (also spelled almanack and almanach) is an annual publication containing tabular information in a particular field or fields often arranged according to the calendar. Astronomical data and various statistics are also found in almanacs, such as the times of the rising and setting of the sun and moon, eclipses, hours of full tide, stated festivals of churches, terms of courts, lists of all types, timelines, and more.
Currently published almanacs such as Whitaker's Almanack have expanded their scope and contents beyond that of their historical counterparts. Modern almanacs include a comprehensive presentation of statististical and descriptive data covering the entire world. Contents also include discussions of topical developments and a summary of recent historical events. Other currently published almanacs (ca. 2006) include TIME Almanac with Information Please, World Almanac and Book of Facts, The Farmer's Almanac and The Old Farmer's Almanac.
Major topics covered by almanacs (reflected by their tables of contents) include: geography, government, demographics, agriculture, economics and business, health and medicine, religion, mass media, transportation, science and technology, sport, and awards/prizes.
Modern or contemporary use of the word almanac has come to mean a chronology or time-table of events such as The Almanac of American Politics published by the National Journal, or The Almanac of American Literature, etc..
