An almanac (also spelled almanack and almanach) is an annual publication listing a set of current information about one or multiple subjects. [1] It includes information like weather forecasts, farmers' planting dates, tide tables, and other tabular data often arranged according to the calendar. Celestial figures and various statistics are found in almanacs, such as the rising and setting times of the Sun and Moon, dates of eclipses, hours of high and low tides, and religious festivals. The set of events noted in an almanac may be tailored for a specific group of readers, such as farmers, sailors, or astronomers.



The etymology of the word is unclear. The earliest documented use of the word in any language is in Latin in 1267 by Roger Bacon, where it meant a set of tables detailing movements of heavenly bodies including the Moon.

It has been suggested that the word almanac derives from a Greek word meaning calendar. [2] However, that word appears only once in antiquity, by Eusebius who quotes Porphyry as to the Coptic Egyptian use of astrological charts (almenichiaká). The earliest almanacs were calendars that included agricultural, astronomical, or meteorological data. But it is highly unlikely Roger Bacon received the word from this etymology: "Notwithstanding the suggestive sound and use of this word (of which however the real form is very uncertain), the difficulties of connecting it historically either with the Spanish Arabic manākh, or with Medieval Latin almanach without Arabic intermediation, seem insurmountable." [3]

One etymology report says "The ultimate source of the word is obscure. Its first syllable, al-, and its general relevance to medieval science and technology, strongly suggest an Arabic origin, but no convincing candidate has been found". [4] Ernest Weekley similarly states of almanac: "First seen in Roger Bacon. Apparently from Spanish Arabic, al-manakh, but this is not an Arabic word....The word remains a puzzle." [5] Walter William Skeat concludes that the construction of an Arabic origin is "not satisfactory". [6] The Oxford English Dictionary similarly says "the word has no etymon in Arabic" but indirect circumstantial evidence "points to a Spanish Arabic al-manākh". [7]

The reason why the proposed Arabic word is speculatively spelled al-manākh is that the spelling occurred as "almanach", as well as almanac (and Roger Bacon used both spellings). The earliest use of the word was in the context of astronomy calendars.

The prestige of the Tables of Toledo and other medieval Arabic astronomy works at the time of the word's emergence in the West, together with the absence of the word in Arabic, suggest it may have been invented in the West and is pseudo-Arabic. At that time in the West, it would have been prestigious to attach an Arabic appellation to a set of astronomical tables. Also around that time, prompted by that motive, the Latin writer Pseudo-Geber wrote under an Arabic pseudonym. (The later alchemical word alkahest is known to be pseudo-Arabic.)


Hemerologies and parapegmata

The earlier texts considered to be almanacs have been found in the Near East, dating back to the middle of the second millennium BC. They have been called generally hemerologies, from the Greek hēmerā, meaning "day". Among them is the so-called Babylonian Almanac, which lists favorable and unfavorable days with advice on what to do on each of them. Successive variants and versions aimed at different readership have been found. [8] Egyptian lists of good and bad moments, three times each day, have also been found. Many of these prognostics were connected with celestial events. [9] [10] [11] The flooding of the Nile valley, a most important event in ancient Egypt, was expected to occur at the summer solstice, but as the civil calendar had exactly 365 days, over the centuries, the date was drifting in the calendar. [note 1] The first heliacal rising of Sirius was used for its prediction and this practice, the observation of some star and its connecting to some event apparently spread.

The Greek almanac, known as parapegma, has existed in the form of an inscribed stone on which the days of the month were indicated by movable pegs inserted into bored holes, hence the name. There were also written texts and according to Diogenes Laërtius, Parapegma was the title of a book by Democritus. [12] Ptolemy, the Alexandrian astronomer (2nd century) wrote a treatise, Phaseis—"phases of fixed stars and collection of weather-changes" is the translation of its full title—the core of which is a parapegma, a list of dates of seasonally regular weather changes, first appearances and last appearances of stars or constellations at sunrise or sunset, and solar events such as solstices, all organized according to the solar year. With the astronomical computations were expected weather phenomena, composed as a digest of observations made by various authorities of the past. Parapegmata had been composed for centuries.

Ptolemy believed that astronomical phenomena caused the changes in seasonal weather; his explanation of why there was not an exact correlation of these events was that the physical influences of other heavenly bodies also came into play. Hence for him, weather prediction was a special division of astrology. [13]

Ephemerides, zijs and tables

The origins of the almanac can be connected to ancient Babylonian astronomy, when tables of planetary periods were produced in order to predict lunar and planetary phenomena. [14] Similar treatises called Zij were later composed in medieval Islamic astronomy.

The modern almanac differs from Babylonian, Ptolemaic and Zij tables in the sense that "the entries found in the almanacs give directly the positions of the celestial bodies and need no further computation", in contrast to the more common "auxiliary astronomical tables" based on Ptolemy's Almagest. The earliest known almanac in this modern sense is the Almanac of Azarqueil written in 1088 by Abū Ishāq Ibrāhīm al-Zarqālī (Latinized as Arzachel) in Toledo, al-Andalus. The work provided the true daily positions of the sun, moon and planets for four years from 1088 to 1092, as well as many other related tables. A Latin translation and adaptation of the work appeared as the Tables of Toledo in the 12th century and the Alfonsine tables in the 13th century. [15]

After almanacs were devised, people still saw little difference between predicting the movements of the stars and tides, and predicting the future in the divination sense. Early almanacs therefore contained general horoscopes, as well as the more concrete information. In 1150 Solomon Jarchus created such an almanac considered to be among the first modern almanacs. Copies of 12th century almanacs are found in the British Museum, and in the Universities of Oxford and Cambridge. In 1300, Petrus de Dacia created an almanac (Savilian Library, Oxford). This was the same year Roger Bacon, OFM, produced his as well. In 1327 Walter de Elvendene created an almanac and later on John Somers of Oxford, in 1380. In 1386 Nicholas de Lynne, Oxford produced an almanac. In 1457 the first printed almanac was published at Mainz, by Gutenberg (eight years before the famous Bible). Regio-Montanus produced an almanac in 1472 (Nuremberg, 1472), which was continued in print for several centuries in many editions. In 1497 the Sheapheard’s Kalendar , translated from French (Richard Pynson) became the first English printed almanac.

By the second half of the 16th century, yearly almanacs were being produced in England by men such as Anthony Askham, Thomas Buckminster, John Dade and Gabriel Frende. In the 17th century, English almanacs were bestsellers, second only to the Bible; by the middle of the century, 400,000 almanacs were being produced annually (a complete listing can be found in the English Short Title Catalogue). Until its deregulation in 1775, the Stationers' Company maintained a lucrative monopoly over almanac publication in England. [17] Richard Allestree (who is not the same as this Richard Allestree) wrote one of the more popular English almanacs, producing yearly volumes from 1617 to 1643, but his is by no means the earliest or the longest-running almanac.

Works that satirized this type of publication appeared in the late 1500s. During the next century, a writer using the pseudonym of "Poor Richard, Knight of the Burnt Island" began to publish a series of such parodies that were entitled Poor Robin's Almanack . The 1664 issue of the series stated: "This month we may expect to hear of the Death of some Man, Woman, or Child, either in Kent or Christendom." [18]

British America and United States

The first almanac printed in the Thirteen Colonies of British America was William Pierce's 1639 An Almanac Calculated for New England . The almanac was the first in a series of such publications that Stephen Daye, or Day, printed each year until 1649 in Cambridge, Massachusetts. [19] The Cambridge/Boston area in Massachusetts soon became the first center in the colonies for the annual publication of almanacs, [20] to be followed by Philadelphia during the first half of the eighteenth century. [21]

Nathaniel Ames of Dedham, Massachusetts, issued his popular Astronomical Diary and Almanack in 1725 and annually after c.1732. [22] James Franklin published The Rhode Island Almanack by "Poor Robin" for each year from 1728 to 1735. [23] James' brother, Benjamin Franklin, published his annual Poor Richard's Almanack in Philadelphia from 1732 to 1758. [24]

Samuel Stearns of Paxton, Massachusetts, issued the North-American Almanack, published annually from 1771 to 1784, as well as the first American nautical almanac, The Navigator's Kalendar, or Nautical Almanack, for 1783. [25] Andrew Ellicott of Ellicott's Upper Mills, Maryland, authored a series of almanacs, The United States Almanack, the earliest known copy of which bears the date of 1782. [26] Benjamin Banneker, a free African American living near Ellicott's Mills, composed a series of almanacs for the years of 1792 to 1797. [27]

Contemporary use

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 statistical 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 and The Almanac for Farmers & City Folk. The Inverness Almanac, an almanac/literary journal, was published in West Marin, California, from 2015 to 2016. [28] In 2007, Harrowsmith Country Life Magazine launched a Canadian Almanac, written in Canada, with all-Canadian content. The nonprofit agrarian organization the Greenhorns currently publishes The New Farmer's Almanac as a resource for young farmers. [29]

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.

Other examples include The Almanac of American Politics published by Columbia Books & Information Services, The Almanac of American Literature, The Almanac of British Politics and the Wapsipinicon Almanac.

The GPS almanac, as part of the data transmitted by each GPS satellite, contains coarse orbit and status information for all satellites in the constellation, an ionospheric model, and information to relate GPS derived time to Coordinated Universal Time (UTC). Hence the GPS almanac provides a similar goal as the ancient Babylonian almanac, to find celestial bodies. [30]

The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon. This means that the lunar hemisphere facing Earth – the near side – is completely sunlit and appears as a circular disk. The full moon occurs roughly once a month.

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy. It was not completely separated in Europe during the Copernican Revolution starting in 1543. In some cultures, astronomical data was used for astrological prognostication. The study of astronomy has received financial and social support from many institutions, especially the Church, which was its largest source of support between the 12th century to the Enlightenment.

Benjamin Banneker Free African-American scientist, surveyor, almanac author and farmer

Benjamin Banneker was a free African-American almanac author, surveyor, landowner and farmer who had knowledge of mathematics and natural history. Born in Baltimore County, Maryland, to a free African-American woman and a former slave, Banneker had little or no formal education and was largely self-taught. He became known for assisting Major Andrew Ellicott in a survey that established the original borders of the District of Columbia, the federal capital district of the United States.

In astronomy and celestial navigation, an ephemeris gives the trajectory of naturally occurring astronomical objects as well as artificial satellites in the sky, i.e., the position over time. The etymology is from Latin ephemeris 'diary' and from Greek ἐφημερίς (ephemeris) 'diary, journal'. Historically, positions were given as printed tables of values, given at regular intervals of date and time. The calculation of these tables was one of the first applications of mechanical computers. Modern ephemerides are often computed electronically, from mathematical models of the motion of astronomical objects and the Earth. However, printed ephemerides are still produced, as they are useful when computational devices are not available.

<i>Poor Richards Almanack</i> Almanac published by Benjamin Franklin

Poor Richard's Almanack was a yearly almanac published by Benjamin Franklin, who adopted the pseudonym of "Poor Richard" or "Richard Saunders" for this purpose.

Stars in astrology

In astrology, certain stars are considered significant. Historically, all of the various heavenly bodies considered by astrologers were considered "stars", whether they were stars, planets, other stellar phenomena like novas and supernovas, or other solar system phenomena like comets and meteors.

The Astronomical Almanac is an almanac published by the United States Naval Observatory (USNO) and Her Majesty's Nautical Almanac Office (HMNAO); it also includes data supplied by many scientists from around the world. It is considered a worldwide resource for fundamental astronomical data, often being the first publication to incorporate new International Astronomical Union resolutions. The almanac largely contains solar system ephemeris and catalogs of selected stellar and extragalactic objects. The material appears in sections, each section addressing a specific astronomical category. The book also includes references to the material, explanations, and examples. It is available one year in advance of its date.

Egyptian astronomy

Egyptian astronomy begins in prehistoric times, in the Predynastic Period. In the 5th millennium BCE, the stone circles at Nabta Playa may have made use of astronomical alignments. By the time the historical Dynastic Period began in the 3rd millennium BCE, the 365 day period of the Egyptian calendar was already in use, and the observation of stars was important in determining the annual flooding of the Nile.

Nathan Daboll was an American teacher who wrote the mathematics textbook most commonly used in American schools in the first half of the 19th century.

Dudley Leavitt (publisher)

Dudley Leavitt was an American publisher. He was an early graduate of Phillips Exeter Academy in his native town of Exeter, New Hampshire, and later moved to Gilmanton where he first edited a newspaper and taught school. Within a few years, Leavitt relocated to Meredith, where in addition to teaching school and farming, he began publishing in 1797 Leavitt's Farmers Almanack, one of the nation's earliest farmers' almanacs. A polymath, Leavitt poured his knowledge of disparate fields including mathematics, language and astronomy into the wildly popular almanacs, which outlived their creator, being published until 1896. The inaugural issue of 1797 carried the title of The New England Calendar: Or, Almanack for the Year of Our Lord 1797. On the cover was the disclaimer that the new publication was "Calculated for the Meridian of Concord, Latitude 43° 14' N. Longitude 72° 45' W.: And with But Little Variation Will Answer for Any of the New England States."

Colonial American astronomy can be traced to the time when the English began colonizing in the New World during the 16th century. They brought with them their interest in astronomy. At first, astronomical thought in America was based on Aristotelian philosophy.

According to accounts that began to appear during the 1960s or earlier, a substantial mythology has exaggerated the accomplishments of Benjamin Banneker (1731–1806), who was a free African-American almanac author, surveyor, landowner and farmer who had knowledge of mathematics, astronomy and natural history. Well-known speakers, writers, artists and others have created, repeated and embellished a large number of such questionable reports during the two centuries that have elapsed since Banneker lived.

A tradition of almanacs published for the purposes of North America began in New England in the 17th century. A New World's dwelling would seldom be found without the latest print of North American almanac and The Pilgrim's Progress.
