Computus (Latin for computation) is the calculation of the date of Easter in the Christian calendar. The name has been used for this procedure since the early Middle Ages, as it was one of the most important computations of the age. The canonical rule is that Easter Sunday is the first Sunday after the 14th day of the lunar month (the nominal full moon) that falls on or after 21 March (nominally the day of the vernal equinox). For determining the feast, Christian churches settled on a method to define a reckoned "ecclesiastic" ...

Computus - Gregorian calendar. This method for the computation of the date of Easter was introduced with the Gregorian calendar reform in 1582. First determine the epact for the year. The epact can have a value from "*" (=0 or 30) to 29 days. The first day of a lunar month is considered the day of the New Moon. The 14th day is considered the day of the Full Moon. The epacts for the current (anno 2003) Metonic cycle are: (M=March, A=April) This table can be extended for previous and following 19-y ...

Epacts are used to find the date in the lunar calendar from the date in the common solar calendar. Epact - Solar and lunar years. A (solar) calendar year usually has 365 days (366 days in leap years). A lunar year usually has 12 synodic months, that last about 29+½ days (and a bit) on average. So the lunar year has months that start with the New Moon and alternate between 30 and 29 days in length, and the lunar year is counted to have 12 × 29.5 = 354 days. So the solar yea ...

The Runic alphabets are a set of related alphabets using letters known as runes, formerly used to write Germanic languages, mainly in Scandinavia and the British Isles. In all their varieties they may be considered an ancient writing system of Northern Europe. The Scandinavian version is known as Futhark (derived from its first six letters: 'F', 'U' 'Th', 'A', 'R', and 'K'), and the Anglo-Saxon version as Futhorc (also so named after its first letters). The earliest runic inscriptions date from ca. 150, and the al ...

In a few, predominantly Eastern Orthodox, nations, religious holidays are celebrated on the corresponding day in the Julian Calendar. From 1900 until 2100, there is a thirteen-day difference between the Julian and the Gregorian Calendar, which is used in most of the world as well as in Eastern Orthodox countries for civil purposes. Thus, for example, Christmas is celebrated on January 7 in these countries. The computation of the day of Easter is, however, completely different between the tw ...

Some Protestant churches recognize a liturgical year, including Anglicans, Methodists, Presbyterians and Lutherans. In general those Protestant churches that recognize a liturgical year, and follow a conventional lectionary, follow the pre-Vatican II Roman Catholic parlance, recognizing an Epiphany Season (or "Sundays after Epiphany") and a Pentecost Season (or "Sundays after Pentecost"). Some Christian festivals and when they occur according to Roman and Protestant (Western) Christianity are: Epiphany: January 6See also:

The runes were introduced to, or invented by, the Germanic peoples in the 1st or 2nd century (The oldest known runic inscription dates to ca. the 160s and is found on a comb discovered in the bog of Vimose, Funen. The inscription reads harja). While at this time the Germanic language was certainly not at the Proto-Germanic stage any longer, it may still have been a continuum of dialects not yet clearly separated into the three branches of later centuries, viz. North Germanic, West Germanic and East Germanic. Most of the early runes fr ...

In the 7th century appeared an intermediary form of runes between the Elder Futhark and the Younger Futhark, but there are very few inscriptions. Two of them are the Stentoften Runestone and the Björketorp Runestone, where the haglaz rune has evolved into having the same form as the h-rune of the younger futhark, but it is used for an a-phoneme. The k-rune, which looks like a Y is a transition form between and in the two futharks. The two futharks were in parallel use f ...

The Younger Fuþark, also called Scandinavian Fuþark, is a reduced form of the Elder Futhark, consisting of only 16 characters. The reduction correlates with phonetic changes when Proto-Norse evolved into Old Norse. They are found in Scandinavia and Viking Age settlements abroad, probably in use from the 9th century onward. They are divided into long-branch (Danish) and short-twig (Swedish and Norwegian) runes. The difference between the two versions has been a matter of controversy. A general opinion is that the difference was functional, ...

Runic alphabet - Third Reich. Runes have been used in Nazi symbolism by National Socialists and neo-Nazi groups that associate themselves with Germanic traditions, mainly the Sigel, Eihwaz, Tyr, Odal (see Odalism) and Algiz runes. The fascination that runes seem to have exerted on the Nazis can be traced to the occult and völkisch author Guido von List, one of the important figures in Germanic mysticism and runic revivalism in the late 19th and early 20th century. In 1908, List published in Das Geheimn ...
