Tabular Islamic Calendar
The Tabular Islamic calendar () is a rule-based variation of the Islamic calendar. It has the same numbering of years and months, but the months are determined by arithmetical rules rather than by observation or astronomical calculations. It was developed by early Muslim astronomers of the second hijra century (the 8th century of the Common Era) to provide a predictable time base for calculating the positions of the moon, sun, and planets. It is now used by historians to convert an Islamic date into a Western calendar when no other information (like the day of the week) is available. Its calendar era is the Hijri year. An example is the Fatimid or Misri calendar. It is used by some Muslims in everyday life, particularly in Ismaili and Shi'a communities, believing that this calendar was developed by Ali. It is believed that when Ali drew up this calendar, the previous events of the earlier prophets also fell into line with this calendar. It is their belief that all Fatimid Imam ...

Islamic Calendar
The Hijri calendar (), also known in English as the Islamic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the Ramadan, annual fasting and the annual season for the Hajj, great pilgrimage. In almost all countries where the predominant religion is Islam, the civil calendar is the Gregorian calendar, with Assyrian calendar, Syriac month-names used in the Arabic names of calendar months#Levant and Mesopotamia, Levant and Mesopotamia (Iraq, Syria, Jordan, Lebanon and Palestine), but the religious calendar is the Hijri one. This calendar enumerates the Hijri era, whose Epoch (reference date), epoch was established as the Islamic New Year in 622 Common Era, CE. During that year, Muhammad and his followers migrated from Mecca to Medina and established the first Muslim community (''ummah''), an event commemorated as the Hijrah.

Kūshyār Ibn Labbān
Abul-Hasan Kūshyār ibn Labbān ibn Bashahri Daylami (971–1029), also known as Kūshyār Daylami (), was an Iranian mathematician, geographer, and astronomer from Daylam, south of the Caspian Sea, Iran. Career Kūshyār Daylami's main work was probably done about the beginning of the 11th century, and seems to have taken an important part in the elaboration of trigonometry. He continued the investigations of the 10th century mathematician and astronomer Abul Wáfa, and devoted much space to this in his (book of astronomical tables) ("The Comprehensive and Mature Tables"), which incorporated the improved values of the planetary apogees observed by al-Battani. The tables were translated into the Persian language before the end of the century. He wrote also an astrological introduction and an arithmetic treatise ('' Principles of Hindu Reckoning'', that is extant in both Arabic and Hebrew), and was translated to English in 1963. Kūshyār Daylami's pupils included the Persi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dawoodi Bohras
The Dawoodi Bohras are a religious denomination within the Ismā'īlī branch of Shia Islam. They number approximately one million worldwide and have settled in over 40 countries around the world. The majority of the Dawoodi Bohra community resides in India, with sizable congregations in Pakistan, Yemen, East Africa, and the Middle East. They also have a growing presence in Europe, North America, and Australia. The Dawoodi Bohra community follows Islam and is specifically identified as Shia Fatimid Ismaili Tayyibi Dawoodi Bohra. Their faith is founded on the conviction that there is only one God, that the Quran is the message of God, that the Islamic prophet Muhammad is the last of the prophets, and that Ali is his legatee and successor. They follow the tenets of Islam, such as reciting the Quran, performing the five daily prayers (Salah), annual tithes of 2.5% (or 1⁄40) of total income and savings (Zakat), fasting during the month of Ramadan (Sawm), the mandatory Hajj pil ...

Dutch East Indies
The Dutch East Indies, also known as the Netherlands East Indies (; ), was a Dutch Empire, Dutch colony with territory mostly comprising the modern state of Indonesia, which Proclamation of Indonesian Independence, declared independence on 17 August 1945. Following the Indonesian National Revolution, Indonesian War of Independence, Indonesia and the Netherlands Dutch–Indonesian Round Table Conference, made peace in 1949. In the Anglo-Dutch Treaty of 1824, the Dutch ceded the governorate of Dutch Malacca to Britain, leading to its eventual incorporation into Malacca, Malacca (state) of modern Malaysia. The Dutch East Indies was formed from the nationalised Factory (trading post), trading posts of the Dutch East India Company, which came under the administration of the Batavian Republic, Dutch government in 1800. During the 19th century, the Dutch fought Royal Netherlands East Indies Army, many wars against indigenous rulers and peoples, which caused hundreds of thousands of d ...

Al-Bīrūnī
Abu Rayhan Muhammad ibn Ahmad al-Biruni (; ; 973after 1050), known as al-Biruni, was a Khwarazmian Iranian scholar and polymath during the Islamic Golden Age. He has been called variously "Father of Comparative Religion", "Father of modern geodesy", Founder of Indology and the first anthropologist. Al-Biruni was well versed in physics, mathematics, astronomy, and natural sciences, and also distinguished himself as a historian, chronologist, and linguist. He studied almost all the sciences of his day and was rewarded abundantly for his tireless research in many fields of knowledge. Royalty and other powerful elements in society funded al-Biruni's research and sought him out with specific projects in mind. Influential in his own right, al-Biruni was himself influenced by the scholars of other nations, such as the Greeks, from whom he took inspiration when he turned to the study of philosophy. A gifted linguist, he was conversant in Khwarezmian, Persian, Arabic, and Sanskrit, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taiyabi Ismaili
Tayyibi Isma'ilism () is the only surviving sect of the Musta'li branch of Isma'ilism, the other being the extinct Hafizi branch. Followers of Tayyibi Isma'ilism are found in various Bohra communities: Dawoodi, Sulaymani, and Alavi. The Tayyibi originally split from the Fatimid Caliphate-supporting Hafizi branch by supporting the right of at-Tayyib Abu'l-Qasim to the Imamate. History Upon the death of the twentieth Imam, al-Amir bi-Ahkam Allah (d. ), his new born child at-Tayyib Abu'l-Qasim (b. ) was appointed the twenty-first Imam. As he was not in a position to run the Dawah, the Queen Arwa al-Sulayhi, his Hujjah or proof, established the office of the Da'i al-Mutlaq, who acted on his behalf. The Da'i al-Mutlaq had now been given absolute authority and made independent from political activity. Da'i al-Mutlaq Dhu'ayb ibn Musa Da'i al-Mutlaq Zoeb bin Moosa used to live in and died in Huth, Yemen. His ''ma'zoon'' ("associate") was Khattab bin Hasan. After the deat ...

Alfonsine Tables
The ''Alfonsine Tables'' (, ), sometimes spelled ''Alphonsine Tables'', provided data for computing the position of the Sun, Moon and planets relative to the fixed stars. The tables were named after Alfonso X of Castile, who sponsored their creation. They were compiled in Toledo, Spain, and contain astronomical data starting on June 1, 1252, the date of the coronation of the King. Production Alfonso X assembled a team of scholars, known as the Toledo School of Translators, who among other translating tasks, were asked to produce new tables that updated the '' Tables of Toledo''. The new tables were based on earlier astronomical works and observations by Islamic astronomers, adding observations by astronomers Alfonso had gathered in Toledo, among them several Jewish scholars, like Yehuda ben Moshe and Isaac ibn Sid. He also brought Aben Raghel y Alquibicio and Aben Musio y Mohamat, from Seville, Joseph Aben Alí and Jacobo Abenvena, from Córdoba, and fifty more from Gas ...

Toledan Tables
The ''Toledan Tables'', or ''Tables of Toledo'', were astronomical tables which were used to predict the movements of the Sun, Moon and planets relative to the fixed stars. They were a collection of mathematical tables that describe different aspects of the cosmos including prediction of calendar dates, times of cosmic events, and cosmic motion. Origins The Toledan Tables were completed around 1080 by a group of Arabic astronomers at Toledo, Spain. They had started as preexisting Arabic tables made elsewhere, and were numerically adjusted to be centered on the location of Toledo. The Tables of Toledo were partly based on the work of al-Zarqali (known to the West as Arzachel), an Arab mathematician, astronomer, astronomy instrument-maker, and astrologer, who lived in Toledo. The tables were produced by a team whose membership is largely unknown, with the exception of al-Zarqali. Toledo came under Christian Spanish rule in the mid-1080s, shortly after the tables were completed. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Al-Battānī
Al-Battani (before 858929), archaically Latinized as Albategnius, was a Muslim astronomer, astrologer, geographer and mathematician, who lived and worked for most of his life at Raqqa, now in Syria. He is considered to be the greatest and most famous of the astronomers of the medieval Islamic world. Al-Battānī's writings became instrumental in the development of science and astronomy in the west. His (), is the earliest extant (astronomical table) made in the Ptolemaic tradition that is hardly influenced by Hindu or Sasanian astronomy. Al-Battānī refined and corrected Ptolemy's ''Almagest'', but also included new ideas and astronomical tables of his own. A handwritten Latin version by the Italian astronomer Plato Tiburtinus was produced between 1134 and 1138, through which medieval astronomers became familiar with al-Battānī. In 1537, a Latin translation of the was printed in Nuremberg. An annotated version, also in Latin, published in three separate volumes between ...
