Klinghammer's Computus
Klinghammer's computus is a mechanism determining the elements of the computus, in particular the date of Easter in the Gregorian calendar. This mechanism was built in the 1970s by Frédéric Klinghammer (1908–2006) and is nearly a reduced model of the computus found on the Strasbourg cathedral astronomical clock. Frédéric Klinghammer (1908-2006) Frédéric Klinghammer was a former employee of the Ungerer company, a company which used to take care of the Strasbourg astronomical clock. He was then seriously involved in the design and building of the Messina astronomical clock. Later, he set down in Moulins (France) and spend the 1970s in Morocco where he built his computus. How it works Klinghammer's computus works along the lines of Jean-Baptiste Schwilgué's computus, which was described in the reference books of 1922 and 1992. Klinghammer's computus was restored by Joseph Flores in 2006-2007 who published a book on it. Flores' book was the subject of critiques, in part becaus ...

Computus
As a moveable feast, the date of Easter is determined in each year through a calculation known as (). Easter is celebrated on the first Sunday after the Paschal full moon, which is the first full moon on or after 21 March (a fixed approximation of the March equinox). Determining this date in advance requires a correlation between the lunar months and the solar year, while also accounting for the month, date, and weekday of the Julian or Gregorian calendar. The complexity of the algorithm arises because of the desire to associate the date of Easter with the date of the Jewish feast of Passover which, Christians believe, is when Jesus was crucified. It was originally feasible for the entire Christian Church to receive the date of Easter each year through an annual announcement by the Pope. By the early third century, however, communications in the Roman Empire had deteriorated to the point that the church put great value in a system that would allow the clergy to determine ...

Strasbourg Astronomical Clock
The Strasbourg astronomical clock is located in the Cathédrale Notre-Dame of Strasbourg, Alsace, France. It is the third clock on that spot and dates from the time of the first French possession of the city (1681–1870). The first clock had been built in the 14th century, the second in the 16th century, when Strasbourg was a Free imperial city of the Holy Roman Empire. The current, third clock dates from 1843. Its main features, besides the automata, are a perpetual calendar (including a ''computus''), an orrery (planetary dial), a display of the real position of the Sun and the Moon, and solar and lunar eclipses. The main attraction is the procession of the 18 inch high figures of Christ and the Apostles, which occurs every day at solar noon, while the life-size cock crows thrice. Clocks First clock The Third of its kind against the south transept. The name of its maker is not known. This clock was known as the "Three Kings clock" and had several automata. One of them ...

Messina Astronomical Clock
The astronomical clock of Messina is an astronomical clock constructed by the Ungerer Company of Strasbourg in 1933. It is built into the campanile of Messina Cathedral. The mechanism was designed by Frédéric Klinghammer, with the artistic design based on plans by Théodore Ungerer. Parts of the design are similar to the Strasbourg astronomical clock. It was commissioned by the Archbishop of Messina ( Angelo Paino) to mark the reconstruction of the campanile after the 1908 Messina earthquake, on the advice of Pope Pius XI, who gave him a functioning model of the Strasbourg clock. The clock's displays appear in several different levels of the campanile, on the sides facing the square and the cathedral. Components The side of the campanile facing the square has the following displays, described from bottom to top: * The carousel of the days of the week. Each day is represented by its classical deity, in a chariot pulled by an animal: ** Sunday: Apollo, driving a horse ** Monda ...

Jean-Baptiste Schwilgué
Jean-Baptiste Schwilgué (born in Strasbourg in 1776, died in the same place in 1856) was the author of the third astronomical clock of Strasbourg Cathedral, built between 1838 and 1843 (not 1842, as it is written on the clock itself). In 1844 Schwilgué, together with his son Charles, patented a key-driven calculating machine (see the link in the External Links section), which seems to be the third key-driven machine in the world, after that of Luigi Torchi (1834) and James White (1822). He produced a number of clocks for church towers, of which the only one still functioning in Strasbourg is that of Saint Aurelia’s Church, Strasbourg The Church of Saint Aurelia (église Sainte-Aurélie), situated in the west of Strasbourg near the railway station, is one of the Strasbourg churches with the longest history. A Lutheran church since the Reformation, the church is of particular hi .... Gallery File:Jean-Baptiste Schwilgué-Buste (1).JPG, Bust of Jean-Baptiste Schwilgué File:Fr ...
