An almanac is a calendar, in which are set down the rising and setting of the sun, the phases of the moon, the most remarkable positions and phenomena of the heavenly bodies, for every month and day of the year; also the several fasts and feasts to be observed in the church and state, etc, and often much miscellaneous information likely to be useful to the public.
The term is of Arabic origin, but the Arabs were not the first to use almanacs, which indeed existed from remote ages. In England they are known from the fourteenth century, there being several English almanacs of this century existing in manuscript form. They became generally used in Europe within a short time after the invention of printing; and they were very early remarkable, as some are still, for the mixture of truth and falsehood which they contained. Their effects in France were found so mischievous, from the pretended prophecies which they published, that an edict was promulgated by Henry III in 1579 forbidding any predictions to be inserted in them relating to civil affairs, whether those of the state or of private persons.
In the reign of James I of England letters-patent were granted to the two universities and the Stationers' Company for an exclusive right of printing almanacs, but in 1775 this monopoly was abolished. During the English Civil War, and thence onward, English almanacs were conspicuous for the unblushing boldness of their astrological predictions, and their determined perpetuation of popular errors. The most famous English almanac was Poor Robin's Almanac, which was published from 1663 to 1775.
Gradually, however, a better taste began to prevail, and in 1828 the Society for the Diffusion of Useful Knowledge, by publishing the British Almanac, had the merit of taking the lead in the production of an unexceptionable almanac in Great Britain. The example thus set has been almost universally adopted. The circulation of almanacs continued to be much cramped by the very heavy duty of one shilling and threepence per copy until 1834, when this duty was abolished. About 200 new almanacs were started immediately on the repeal.
Almanacs, from their periodical character, and the frequency with which they are referred to, are now more and more used as vehicles for conveying statistical and other useful information, some being intended for the inhabitants of a particular country or district, others for a particular class or party. Some of the almanacs that are regularly published every year are extremely useful, and before the Internet and improved communications were almost indispensable to men engaged in official, mercantile, literary, and professional business. Such in Great Britain were Thorn's Official Directory of the United Kingdom, the British Almanac, Oliver and Boyd's Edinburgh Almanac, and Whitaker's Almanac, now so well known.
In the United States was published The American Almanac, a useful compilation. The Almanach de Gotha, which first appeared at Gotha in 1764, contained in small bulk a wonderful quantity of information regarding the reigning families and governments, the finances, commerce, population, etc, of the different states throughout the world. It was published both in a French and in a German edition. Almanacs that pretend to foretell the weather and occurrences of various kinds are still popular in Britain, France, and elsewhere.
The Nautical Almanack was an important work published annually by the British government, two or three years in advance, in which was contained much useful astronomical matter, more especially the distances of the moon from the sun, and from certain fixed stars, for every three hours of apparent time, adapted to the meridian of the Royal Observatory, Greenwich. By comparing these with the distances carefully observed at sea the mariner could with comparative ease, infer his longitude to a degree of accuracy unattainable in the past by any other way, and sufficient in the past for most nautical purposes. This almanac was commenced in 1767 by Dr. Maskelyne, astronomer royal. The French Connaissance des Temps was published with the same views as the English Nautical Almanac, and nearly on the same plan. It commenced in 1679. Of a similar character was the Astronomisches Jahrbuch formerly published at Berlin. Research Almanac
