The Javanese calendar is the calendar of the Javanese people. It is used concurrently with the Gregorian calendar and the Islamic calendar; the Gregorian calendar is the official calendar of the Republic of Indonesia and civil society, while the Islamic calendar is used by Muslims and the Indonesian government for religious worship and deciding relevant Islamic holidays. The Javanese calendar is used by the main ethnicities of Java island—that is, the Javanese and Sundanese people—primarily as a cultural icon and identifier, as a maintained tradition of antiquity; the Javanese calendar is used for cultural and spiritual purposes. The current system of the Javanese calendar was inaugurated by Sultan Agung of Mataram in the Gregorian year 1633 CE. Prior to this, the Javanese had used the Hindu calendar, which begins in 78 CE and uses the solar cycle for calculating time. Sultan Agung's calendar retained the Saka calendar year system of counting, but differs by using the same lunar year measurement system as the Islamic calendar, rather than the solar year.
The Javanese calendar is referred to by its Latin name Anno Javanico or AJ. The Javanese calendar contains multiple, overlapping measurements of times, called "cycles"; these include: the native five-day week, called Pasaran the common Gregorian and Islamic seven-day week the Solar month, called Mangsa the Lunar month, called Wulan the lunar year, or Tahun the octo-ennia cycles, or Windu the 120-year cycle of 15 Windu, called Kurup Days in the Javanese calendar, like the Islamic calendar, begin at sunset. Traditionally, Javanese people do not divide the night into hours, but rather into phases; the division of a day and night are: The native Javanese system groups days into a five-day week called Pasaran, unlike most calendars that uses a seven-day week. The name, pasaran, is derived from the root word pasar, but still today, Javanese villagers gather communally at local markets to meet, engage in commerce, buy and sell farm produce, cooked foods, home industry crafted items and so on. John Crawfurd suggested that the length of the weekly cycle is related to the number of fingers on the hand, that itinerant merchants would rotate their visits to different villages according to a five-day "roster".
The days of the cycle each have two names, as the Javanese language has distinct vocabulary associated with two different registers of politeness: ngoko and krama. The krama names for the days, second in the list, are much less common. ꦊꦒꦶ – ꦩꦤꦶꦱ꧀ ꦥꦲꦶꦁ – ꦥꦲꦶꦠ꧀ ꦥꦺꦴꦤ꧀ – ꦥꦼꦠꦏ꧀ ꦮꦒꦺ – ꦕꦼꦩꦺꦁ ꦏ꧀ꦭꦶꦮꦺꦴꦤ꧀ – ꦲꦱꦶꦃ The origin of the names is unclear, their etymology remains obscure. The names may be derived from indigenous gods, like the European and Asian names for days of the week. An ancient Javanese manuscript illustrates the week with five human figures: a man seizing a suppliant by the hair, a woman holding a horn to receive an offering, a man pointing a drawn sword at another, a woman holding agricultural produce, a man holding a spear leading a bull. Additionally, Javanese consider these days' names to have a mystical relation to colors and cardinal direction: Legi: white and East Pahing: red and South Pon: yellow and West Wage: black and North Kliwon: blurred colors/focus and'center'. Most Markets no longer operate under this traditional Pasaran cycle, instead pragmatically remaining open every day of the Gregorian week.
However many markets in Java still retain traditional names that indicated that once the markets only operated on certain Pasaran days, such as Pasar Legi, or Pasar Kliwon. Some markets in small or medium size locations will be much busier on the Pasaran day than on the other days. On the market's name day itinerate sellers appear selling such things as livestock and other products that are either less purchased or are more expensive; this allows a smaller number of these merchants to service a much larger area much as in bygone days. Javanese astrological belief dictates that an individual’s characteristics and destiny are attributable to the combination of the Pasaran day and the "common" weekday of the Islamic calendar on that person's birthday. Javanese people find great interest in the astrological interpretations of this combination, called the Wetonan cycle; the seven-day-long week cycle is derived from the Islamic calendar, adopted following the spread of Islam throughout the Indonesian archipelago.
The names of the days of the week in Javanese are derived from their Arabic counterparts, namely: These two-week systems occur concurrently. This combination forms the Wetonan cycle; the Wetonan cycle superimposes the five-day Pasaran cycle with the seven-day week cycle. Each Wetonan cycle lasts for 35 days. An example of Wetonan cycle: From the example above, the Weton for Tuesday May 6, 2008 would be read as Selasa Wage; the Wetonan cycle is important for divinatory systems, important celebrations, rites of passage. Commemorations and events are held on days considered to be auspicious. An prominent example, still taught in primary schools, is that the Weton for the Proclamation of Indonesian Independence on 17 August 1945 took place on Jumat Legi. Therefore, Jumat Legi is considered an important night for pilgrimage. There are taboos
Twenty-sixth Dynasty of Egypt
The Twenty-sixth Dynasty of Egypt was the last native dynasty to rule Egypt before the Persian conquest in 525 BC. The dynasty's reign is called the Saite Period after the city of Sais, where its pharaohs had their capital, marks the beginning of the Late Period of ancient Egypt; this dynasty traced its origins to the Twenty-fourth Dynasty. Psamtik I was a descendant of Bakenranef, following the Neo-Assyrian Empire's invasions during the reigns of Taharqa and Tantamani, he was recognized as sole king over all of Egypt. While the Neo-Assyrian Empire was preoccupied with revolts and civil war over control of the throne, Psamtik threw off his ties to the Assyrians circa 655 BC, formed alliances with King Gyges of Lydia, recruited mercenaries from Caria and ancient Greece to resist Assyrian attacks. With the sack of Nineveh in 612 BC and the fall of the Assyrian Empire, both Psamtik and his successors attempted to reassert Egyptian power in the Near East, but were driven back by the Neo-Babylonian Empire under Nebuchadnezzar II.
With the help of Greek mercenaries, Apries was able to hold back Babylonian attempts to conquer Egypt, only for the Persians to do so. Their king, Cambyses II, captured and executed Psamtik III; the 26th Dynasty may be related to the 24th Dynasty. Manetho begins the dynasty with: Ammeris the Nubian, 12 years Stephinates, 7 years Nechepsos, 6 years Necho, 8 years; when the Nubian King Shabaka defeated Bakenranef, son of Tefnakht, he installed a Nubian commander as governor at Sais. This may be the man named Ammeris. Stephinates may be a descendant of Bakenrenef, he is sometimes referred to as Tefnakht II in the literature. Nechepsos has been identified with a local king named Nekauba. Manetho's Necho is King Necho I. Necho was killed during a conflict with the Nubian king Tantamani. Psamtik I fled to Nineveh – capital of the Neo-Assyrian Empire – and returned to Egypt when Ashurbanipal defeated Tantamani and drove him back south. Scholars now start the 26th Dynasty with the reign of Psamtik I. Sextus Julius Africanus states in his accurate version of Manetho's Epitome that the dynasty numbered 9 pharaohs, beginning with a "Stephinates" and ending with Psamtik III.
Africanus notes that Psamtik I and Necho I ruled for 54 and 8 years respectively.

1st millennium BC
The 1st millennium BC is the period of time between from the year 1000 BC to 1 BC. It encompasses the Iron Age in the Old World and sees the transition from the Ancient Near East to classical antiquity. World population doubled over the course of the millennium, from about 100 million to about 200–250 million; the Neo-Assyrian Empire dominates the Near East in the early centuries of the millennium, supplanted by the Achaemenid Empire in the 6th century. Ancient Egypt is in decline, falls to the Achaemenids in 525 BC. In Greece, Classical Antiquity begins with the colonization of Magna Graecia and peaks with the conquest of the Achaemenids and the subsequent flourishing of Hellenistic civilization; the Roman Republic supplants the Etruscans and the Carthaginians. The close of the millennium sees the rise of the Roman Empire; the early Celts dominate Central Europe. In East Africa, the Nubian Empire and Aksum arise. In South Asia, the Vedic civilization blends into the Maurya Empire; the Scythians dominate Central Asia.
In China, the Spring and Autumn period sees the rise of Confucianism. Towards the close of the millennium, the Han Dynasty extends Chinese power towards Central Asia, where it borders on Indo-Greek and Iranian states. Japan is in the Yayoi period; the Maya civilization rises in Mesoamerica. The first millennium BC is the formative period of the classical world religions, with the development of early Judaism Zoroastrianism in the Near East, Vedic religion and Vedanta and Buddhism in India. Early literature develops in Greek, Hebrew, Sanskrit and Chinese; the term Axial Age, coined by Karl Jaspers, is intended to express the crucial importance of the period of c. the 8th to 2nd centuries BC in world history. World population more than doubled over the course of the millennium, from about an estimated 50–100 million to an estimated 170–300 million. Close to 90% of world population at the end of the first millennium BC lived in the Iron Age civilizations of the Old World; the population of the Americas was below 20 million, concentrated in Mesoamerica.
The population of Oceania was less than one million people. 10th century BC Near East: Neo-Assyrian Empire Near East: Shoshenq I invades Canaan Aegean: Helladic period ends 9th century BC Egypt: 872 BC: Nile floods the Temple of Luxor Egypt: 836 BC: Civil war in Egypt North Africa: 814 BC: Carthage founded China: 841 BCndash.

Ab urbe condita
Ab urbe condita, or Anno urbis conditæ abbreviated as AUC in either case, is a convention, used in antiquity and by classical historians to refer to a given year in Ancient Rome. Ab urbe condita means "from the founding of the City," while anno urbis conditæ means "in the year since the City's founding." Therefore, the traditional year of the foundation of Rome, 753 BC, would be written AUC 1, while AD 1 would be AUC 754. The foundation of the Empire in 27 BC would be AUC 727. Usage of the term was more common during the Renaissance, when editors sometimes added AUC to Roman manuscripts they published, giving the false impression that the convention was used in antiquity. In reality, the dominant method of identifying years in Roman times was to name the two consuls who held office that year. In late antiquity, regnal years were in use, as was the Diocletian era in Roman Egypt after AD 293, in the Byzantine Empire after AD 537, following a decree by Justinian; the traditional date for the founding of Rome, 21 April 753 BC, is due to Marcus Terentius Varro.
Varro may have used the consular list and called the year of the first consuls "ab urbe condita 245," accepting the 244-year interval from Dionysius of Halicarnassus for the kings after the foundation of Rome. The correctness of this calculation has not been confirmed. From the time of Claudius onward, this calculation superseded other contemporary calculations. Celebrating the anniversary of the city became part of imperial propaganda. Claudius was the first to hold magnificent celebrations in honor of the anniversary of the city, in AD 48, the eight hundredth year from the founding of the city. Hadrian and Antoninus Pius held similar celebrations, in AD 121, in AD 147 and AD 148, respectively. In AD 248, Philip the Arab celebrated Rome's first millennium, together with Ludi saeculares for Rome's alleged tenth sæculum. Coins from his reign commemorate the celebrations. A coin by a contender for the imperial throne, explicitly states "ear one thousand and first", an indication that the citizens of the empire had a sense of the beginning of a new era, a Sæculum Novum.
The Anno Domini year numbering was developed by a monk named Dionysius Exiguus in Rome in AD 525, as a result of his work on calculating the date of Easter. Dionysius did not use the AUC convention, but instead based his calculations on the Diocletian era; this convention had been in use since AD 293, the year of the tetrarchy, as it became impractical to use regnal years of the current emperor. In his Easter table, the year AD 532 was equated with the 248th regnal year of Diocletian; the table counted the years starting from the presumed birth of Christ, rather than the accession of the emperor Diocletian on 20 November AD 284, or as stated by Dionysius: "sed magis elegimus ab incarnatione Domini nostri Jesu Christi annorum tempora praenotare". Blackburn and Holford-Strevens review interpretations of Dionysius which place the Incarnation in 2 BC, 1 BC, or AD 1, it has been calculated that the year AD 1 corresponds to AUC 754, based on the epoch of Varro. Thus, AUC 1 = 753 BC AUC 753 = 1 BC AUC 754 = AD 1 AUC 1000 = AD 247 AUC 1229 = AD 476 AUC 2206 = AD 1453 AUC 2753 = AD 2000 AUC 2772 = AD 2019 List of Latin phrases
Balinese saka calendar
The Balinese saka calendar is one of two calendars used on the Indonesian island of Bali. Unlike the 210-day pawukon calendar, it is based on the phases of the Moon, is the same length as the Gregorian year. Based on a lunar calendar, the saka year comprises sasih, of 30 days each. However, because the lunar cycle is shorter than 30 days, the lunar year has a length of 354 or 355 days, the calendar is adjusted to prevent it losing synchronization with the lunar or solar cycles; the months are adjusted by allocating two lunar days to one solar day every 9 weeks. This day is called ngunalatri, Sanskrit for "minus one night". To stop the Saka from lagging behind the Gregorian calendar – as happens with the Islamic calendar, an extra month, known as an intercalary month, is added after the 11th month, or after the 12th month; the length of these months is calculated according to the normal 63-day cycle. An intercalary month is added whenever necessary to prevent the final day of the 7th month, known as Tilem Kapitu, from falling in the Gregorian month of December.
The names the twelve months are taken from a mixture of Old Balinese and Sanskrit words for 1 to 12, are as follows: Kasa Karo Katiga Kapat Kalima Kanem Kapitu Kawalu Kasanga Kadasa Jyestha SadhaEach month begins the day after a new moon and has 15 days of waxing moon until the full moon 15 days of waning, ending on the new moon. Both sets of days are numbered 1 to 15; the first day of the year is the day after the first new moon in March. Note, that Nyepi falls on the first day of Kadasa, that the years of the Saka era are counted from that date; the calendar is 78 years behind the Gregorian calendar, is calculated from the beginning of the Saka Era in India. It is used alongside the 210-day Balinese pawukon calendar, Balinese festivals can be calculated according to either year; the Indian saka calendar was used for royal decrees as early as the ninth century CE. The same calendar was used in Java until Sultan Agung replaced it with the Javanese calendar in 1633; the Balinese Hindu festival of Nyepi, the day of silence, marks the start of the Saka year.
Tilem Kepitu, the last day of the 7th month, is known as Siva Ratri, is a night dedicated to the god Shiva. Devotees stay up all meditate. There are another 24 ceremonial days in the Saka year celebrated at Purnama. Eiseman, Fred B.

Wahibre Psamtik I, known by the Greeks as Psammeticus or Psammetichus, who ruled 664–610 BC, was the first of three kings of that name of the Saite, or Twenty-sixth Dynasty of Egypt. Historical references for what the Greeks referred to as the Dodecarchy, a loose confederation of twelve Egyptian territories, based on the traditional nomes, the rise of Psamtik I in power, establishing the Saitic Dynasty, are recorded in Herodotus's Histories, Book II: 151–157. From cuneiform texts, it was discovered that twenty local princelings were appointed by Esarhaddon and confirmed by Ashurbanipal to govern Egypt. Necho I, the father of Psamtik by his queen Istemabet, was the chief of these kinglets, but they seem to have been quite unable to lead the Egyptians under the hated Assyrians against the more sympathetic Nubians; the labyrinth built by Amenemhat III of the Twelfth Dynasty of Egypt is ascribed by Herodotus to the Dodecarchy, which must represent this combination of rulers. Necho I died in 664 BC when the Kushite king Tantamani tried unsuccessfully to seize control of lower Egypt from the Assyrian Empire.
After his father's death, Psamtik both united all of Egypt and freed it from Assyrian control within the first ten years of his reign. Psamtik reunified Egypt in his ninth regnal year when he dispatched a powerful naval fleet in March 656 BC to Thebes and compelled the existing God's Wife of Amun at Thebes, Shepenupet II, to adopt his daughter Nitocris I as her heiress in the so-called Adoption Stela. Psamtik's victory destroyed the last vestiges of the Nubian Twenty-fifth Dynasty's control over Upper Egypt under Tantamani since Thebes now accepted his authority. Nitocris would hold her office for 70 years from 656 BC until her death in 585 BC. Thereafter, Psamtik campaigned vigorously against those local princes who opposed his reunification of Egypt. One of his victories over certain Libyan marauders is mentioned in a Year 10 and Year 11 stela from the Dakhla Oasis. Psamtik won Egypt's independence from the Assyrian Empire and restored Egypt's prosperity during his 54-year reign; the pharaoh proceeded to establish close relations with archaic Greece and encouraged many Greek settlers to establish colonies in Egypt and serve in the Egyptian army.
In particular, he settled some Greeks at Tahpanhes. The Greek historian Herodotus conveyed an anecdote about Psamtik in the second volume of his Histories. During his travel to Egypt, Herodotus heard that Psammetichus sought to discover the origin of language by conducting an experiment with two children, he gave two newborn babies to a shepherd, with the instructions that no one should speak to them, but that the shepherd should feed and care for them while listening to determine their first words. The hypothesis was; when one of the children cried "βεκός" with outstretched arms, the shepherd concluded that the word was Phrygian because, the sound of the Phrygian word for "bread". Thus, they concluded that the Phrygians were an older people than the Egyptians, that Phrygian was the original language of men. There are no other extant sources to verify this story. Psamtik's chief wife was Mehytenweskhet, the daughter of Harsiese, the vizier of the North and High Priest of Atum at Heliopolis. Psamtik and Mehytenweskhet were the parents of Necho II, the Divine Adoratrice Nitocris I.
Psamtik's father-in-law—the aforementioned Harsiese—was married three times: to Sheta, with whom he had a daughter named Naneferheres, to Tanini and to an unknown woman, by whom he had both Djedkare, the vizier of the South and Mehytenweskhet. Harsiese was the son of vizier Harkhebi, was related to two other Harsieses, both viziers, who were a part of the family of the famous Mayor of Thebes Montuemhat. On 9 March 2017, Egyptian and German archaeologists discovered a colossal statue about 7.9 metres in height at the Heliopolis site in Cairo. Made of quartzite, the statue was found in a fragmentary state, with the bust, the lower part of the head and the crown submerged in groundwater, it has now been confirmed to be of Psamtik I due to engravings found that mentioned one of the pharaoh's names on the base of the statue. A spokesperson at the time commented that "If it does belong to this king it is the largest statue of the Late Period, discovered in Egypt." The head and torso are expected to be moved to the Grand Egyptian Museum.
The statue/colossus was sculpted in the ancient classical style of 2000 BC, establishing a resurgence to the greatness and prosperity of the classical period of old. However, from the many gathered fragments of quartzite collected, it has been established that the colossus was at some time deliberately destroyed. Certain discoloured & cracked rock fragments show evidence of having been heated to high temperatures shattered, a typical way of destroying ancient colossi; this article incorporates text from a publication now in the public domain: Chisholm, Hugh, ed..

An Olympiad is a period of four years associated with the Olympic Games of the Ancient Greeks. Although the Ancient Olympic Games were established during Archaic Greece, it was not until the Hellenistic period, beginning with Ephorus, that the Olympiad was used as a calendar epoch. Converting to the modern BC/AD dating system the first Olympiad began in the summer of 776 BC and lasted until the summer of 772 BC, when the second Olympiad would begin with the commencement of the next games. By extrapolation to the Gregorian calendar, the 3rd year of the 699th Olympiad will begin in mid-summer 2019. A modern Olympiad refers to a four-year period beginning on the opening of the Olympic Games for the summer sports; the first modern Olympiad began in 1896, the second in 1900, so on. The ancient and modern Olympiads would have synchronised had there been a year zero between the Olympiad of 4 BC and the one of 4 AD, but as the Gregorian calendar goes directly from 1 BC to 1 AD, the ancient Olympic cycle now lags the modern cycle by one year.
An ancient Olympiad was a period of four years grouped together, counting inclusively as the ancients did. Each ancient Olympic year overlapped onto two of our modern reckoning of BC or AD years, from midsummer to midsummer. Example: Olympiad 140, year 1 = 220/219 BC. Therefore, the games would have been held in July/August of 220 BC and held the next time in July/August of 216 BC, after four olympic years had been completed; the sophist Hippias was the first writer to publish a list of victors of the Olympic Games, by the time of Eratosthenes, it was agreed that the first Olympic games had happened during the summer of 776 BC. The combination of victor lists and calculations from 776 BC onwards enabled Greek historians to use the Olympiads as a way of reckoning time that did not depend on the time reckonings of one of the city-states; the first to do so was Timaeus of Tauromenium in the third century BC. Since for events of the early history of the games the reckoning was used in retrospect, some of the dates given by historian for events before the 5th century BC are unreliable.
In the 2nd century AD, Phlegon of Tralles summarised the events of each Olympiad in a book called Olympiads, an extract from this has been preserved by the Byzantine writer Photius. Christian chroniclers continued to use this Greek system of dating as a way of synchronising biblical events with Greek and Roman history. In the 3rd century AD, Sextus Julius Africanus compiled a list of Olympic victors up to 217 BC, this list has been preserved in the Chronicle of Eusebius. Early historians sometimes used the names of Olympic victors as a method of dating events to a specific year. For instance, Thucydides says in his account of the year 428 BC: "It was the Olympiad in which the Rhodian Dorieus gained his second victory". Dionysius of Halicarnassus dates the foundation of Rome to the first year of the seventh Olympiad, 752/1 BC. Since Rome was founded on April 21, in the last half of the ancient Olympic year, it would be 751 BC specifically. In Book 1 chapter 75 Dionysius states: "... Romulus, the first ruler of the city, began his reign in the first year of the seventh Olympiad, when Charops at Athens was in the first year of his ten-year term as archon."
Diodorus Siculus dates the Persian invasion of Greece to 480 BC: "Calliades was archon in Athens, the Romans made Spurius Cassius and Proculus Verginius Tricostus consuls, the Eleians celebrated the Seventy-fifth Olympiad, that in which Astylus of Syracuse won the stadion. It was in this year that king Xerxes made his campaign against Greece." Jerome, in his Latin translation of the Chronicle of Eusebius, dates the birth of Jesus Christ to year 3 of Olympiad 194, the 42nd year of the reign of the emperor Augustus, which equates to the year 2 BC. An Olympiad started with the holding of the games, which occurred on the first or second full moon after the summer solstice, in what we call July or August; the games were therefore a new years festival. In 776 BC this occurred on either July 23 or August 21.. Though the games were held without interruption, on more than one occasion they were held by others than the Eleians; the Eleians declared such games Anolympiads, but it is assumed the winners were recorded.
During the 3rd century AD, records of the games are so scanty that historians are not certain whether after 261 they were still held every four years. During the early years of the Olympiad, any physical benefit deriving from a sport was banned; some winners were recorded though, until the last Olympiad of 393AD. In 394, Roman Emperor Theodosius. Though it would have been possible to continue the reckoning by just counting four-year periods, by the middle of the 5th century AD reckoning by Olympiads had become disused; the modern Olympiad is a period of four years, beginning at the opening of the Olympic Summer Games and ending at the opening of the next. The Olympiads are numbered consecutively from the first Games of the Olympiad celebrated in Athens in 1896; the XXXI Olympiad began on August 5, 2016 and will end on July 24, 2020. The Summer Olympics are more referred to as the Games of the Olympiad; the first poster to announce the games using this term was the one for the 1932 Summer Olympics, in Los Angeles, using the phrase: Call to the games of the Xth Olympiad Note, that the official numbering of the Winter Olympics does
