The division of the Catholic Church and the unrest associated with the Hussite movement would become factors in the rise of the Protestant Reformation in the following century. The event forced Western Europeans to find a new route, adding further momentum to what was the beginning of the Age of Discovery. Explorations by the Spanish and Portuguese led to European sightings of the Americas and these expeditions ushered in the era of the Portuguese and Spanish colonial empires. The fall of Constantinople led to the migration of Greek scholars and texts to Italy and these two events played key roles in the development of the Renaissance.

Berber calendar
–
The Berber calendar is the agricultural calendar traditionally used by Berbers. It is also known as the fellaḥi, the calendar is utilized to regulate the seasonal agricultural works. It is used in lieu of the Islamic calendar, a calendar considered ill-adapted for agriculture because it does not relate to seasonal cycles. The current Berber calendar is a legacy of the Roman province of Mauretania Caesariensis, the latter calendar was used in Europe before the adoption of the Gregorian calendar, with month names derived from Latin. Berber populations previously used various indigenous calendars, such as that of the Guanche autochthones of the Canary Islands, however, relatively little is known of these ancient calendrical systems. Not much is known about the division of time among the ancient Berbers, some elements of a pre-Islamic, and almost certainly a pre-Roman calendar, emerge from some medieval writings, analyzed by Nico van den Boogert. Some correspondences with the traditional Tuareg calendar suggest that in antiquity there existed, with degree of diffusion. According to a 17th-century manuscript by Tomás Marín de Cubas, they computed their year, called Acano and it began in summer, when the sun enters in Cancer, on June 21, at the first conjunction they celebrated nine festival days for the crop. The name of one month is known in the native language. It seems it was the month of the year, corresponding to August. Such a name, in case it was made up by something like *wen that of + smet, may correspond, in the list of medieval Berber month names, with the ninth and tenth months, but data are too scarce for this hypothesis to be deepened. The agricultural Berber calendar still in use is almost certainly derived from the Julian calendar, the only slight discrepancy lies in that the extra day in leap years is not usually added at the end of February, but at the end of the year. Jean Servier has doubted that the calendar descends directly from the Julian calendar of the Latin era, there are standard forms for the names of the Amazigh calendar. The table below provides the forms used in Morocco, Algeria and Tunisia. In some areas they may be different due to communication and manipulation by the government. Moreover, pronunciation differs according to the region, the coldest period is made up by 20 white nights, from 12 to 31 dujamber, and 20 black nights, beginning on the first day of yennayer, corresponding to the Gregorian 14 January. The first day of the year is celebrated in various ways in the different parts of North Africa, a widespread tradition is a meal with particular foods, which vary from region to region, but in many zones it is provided by the sacrifice of an animal. In Algeria, such a holiday is celebrated even by people who dont use the Berber calendar in daily life

Philip II of Spain
–
Philip II of Spain, called the Prudent, was King of Spain, King of Portugal, King of Naples and Sicily, and jure uxoris King of England and Ireland. He was also Duke of Milan, from 1555, he was lord of the Seventeen Provinces of the Netherlands. Known in Spain as Felipe el Prudente, his empire included territories on every continent then known to Europeans, during his reign, Spain reached the height of its influence and power. This is sometimes called the Golden Age, the expression, the empire on which the sun never sets, was coined during Philips time to reflect the extent of his dominion. During Philips reign there were separate state bankruptcies in 1557,1560,1569,1575 and this was partly the cause of the declaration of independence that created the Dutch Republic in 1581. The Ambassador went on to say He dresses very tastefully, the culture and courtly life of Spain were an important influence in his early life. He was tutored by Juan Martínez Siliceo, the future Archbishop of Toledo, Philip displayed reasonable aptitude in arms and letters alike. Later he would study with more illustrious tutors, including the humanist Juan Cristóbal Calvete de Estrella, though Philip had good command over Latin, Spanish, and Portuguese, he never managed to equal his father, Charles V, as a polyglot. While Philip was also a German archduke of the House of Habsburg, Philip felt himself to be culturally Spanish, he had been born in Spain and raised in the Castilian court, his native tongue was Spanish, and he preferred to live in Spain. This would ultimately impede his succession to the imperial throne, in April 1528, when Philip was eleven months old, he received the oath of allegiance as heir to the crown from the Cortes of Castile. Philip was also close to his two sisters, María and Juana, and to his two pages, the Portuguese nobleman Rui Gomes da Silva and Luis de Requesens, the son of his governor Juan de Zúñiga. These men would serve Philip throughout their lives, as would Antonio Pérez, Philips martial training was undertaken by his governor, Juan de Zúñiga, a Castilian nobleman who served as the commendador mayor of Castile. The practical lessons in warfare were overseen by the Duke of Alba during the Italian Wars, Philip was present at the Siege of Perpignan in 1542 but did not see action as the Spanish army under Alba decisively defeated the besieging French forces under the Dauphin of France. On his way back to Castile, Philip received the oath of allegiance of the Aragonese Cortes at Monzón. The king-emperors interactions with his son during his stay in Spain convinced him of Philips precocity in statesmanship, Philip, who had previously been made the Duke of Milan in 1540, began governing the most extensive empire in the world at the young age of sixteen. Charles left Philip with experienced advisors—notably the secretary Francisco de los Cobos, Philip was also left with extensive written instructions that emphasised piety, patience, modesty, and distrust. These principles of Charles were gradually assimilated by his son, who would grow up to become grave, self-possessed, personally, Philip spoke softly and had an icy self-mastery, in the words of one of his ministers, he had a smile that cut like a sword. After living in the Netherlands in the years of his reign

Mary I of England
–
Mary I was the Queen of England and Ireland from July 1553 until her death. Her executions of Protestants led to the posthumous sobriquet Bloody Mary and she was the only child of Henry VIII by his first wife Catherine of Aragon to survive to adulthood. Her younger half-brother Edward VI succeeded their father in 1547, when Edward became mortally ill in 1553, he attempted to remove Mary from the line of succession because of religious differences. On his death their first cousin once removed, Lady Jane Grey, was proclaimed queen, Mary assembled a force in East Anglia and deposed Jane, who was ultimately beheaded. Mary was—excluding the disputed reigns of Jane and the Empress Matilda—the first queen regnant of England, in 1554, Mary married Philip of Spain, becoming queen consort of Habsburg Spain on his accession in 1556. Mary is remembered for her restoration of Roman Catholicism after her half-brothers short-lived Protestant reign, during her five-year reign, she had over 280 religious dissenters burned at the stake in the Marian persecutions. After her death in 1558, her re-establishment of Roman Catholicism was reversed by her younger half-sister and successor Elizabeth I, daughter of Henry, Mary was born on 18 February 1516 at the Palace of Placentia in Greenwich, London. She was the child of King Henry VIII by his first wife, Catherine of Aragon. Her mother had many miscarriages, before Marys birth, four previous pregnancies had resulted in a stillborn daughter and she was baptised into the Catholic faith at the Church of the Observant Friars in Greenwich three days after her birth. Her godparents included her great-aunt the Countess of Devon, Lord Chancellor Thomas Wolsey, Henry VIIIs cousin once removed, Margaret Pole, Countess of Salisbury, stood sponsor for Marys confirmation, which was held immediately after the baptism. The following year, Mary became a godmother herself when she was named as one of the sponsors of her cousin Frances Brandon, in 1520, the Countess of Salisbury was appointed Marys governess. Sir John Hussey, later Lord Hussey, was her chamberlain from 1530, in July 1520, when scarcely four and a half years old, she entertained a visiting French delegation with a performance on the virginals. By the age of nine, Mary could read and write Latin and she studied French, Spanish, music, dance, and perhaps Greek. Henry VIII doted on his daughter and boasted to the Venetian ambassador Sebastian Giustiniani, also, as the miniature portrait of her shows, Mary had, like both her parents, a very fair complexion, pale blue eyes and red or reddish-golden hair. She was also ruddy cheeked, a trait she inherited from her father, despite his affection for Mary, Henry was deeply disappointed that his marriage had produced no sons. By the time Mary was nine years old, it was apparent that Henry and Catherine would have no more children, in 1525, Henry sent Mary to the border of Wales to preside, presumably in name only, over the Council of Wales and the Marches. She was given her own based at Ludlow Castle and many of the royal prerogatives normally reserved for the Prince of Wales. Vives and others called her the Princess of Wales, although she was never technically invested with the title and she appears to have spent three years in the Welsh Marches, making regular visits to her fathers court, before returning permanently to the home counties around London in mid-1528

Snake (zodiac)
–
The Snake is one of the 12-year cycle of animals which appear in the Chinese zodiac and related to the Chinese calendar, as well as in related East Asian zodiacal or calendrical systems. The Year of the Snake is associated with the Earthly Branch symbol 巳, according to one mythical legend, there is a reason for the order of the 12 animals in the 12-year cycle. The story goes that a race was held to cross a river. The same 12 animals are used to symbolize the cycle of hours in the day. The hour of the Snake is 9,00 to 11,00 a. m. the time when the sun warms up the earth, the month of the Snake is May 5 to June 5. In Chinese symbology, Snakes are regarded as intelligent, but with a tendency to be somewhat unscrupulous, the Snake is the 6th of the 12 signs and belongs to the Second Trine, together with the Ox and the Rooster, with which it is most compatible. Depictions of zodiacal Snakes either solo or in context with the other eleven zodiacal creatures shows how they have been imagined in the calendrical context.

Hebrew calendar
–
The Hebrew or Jewish calendar is a lunisolar calendar used today predominantly for Jewish religious observances. It determines the dates for Jewish holidays and the public reading of Torah portions, yahrzeits. The present Hebrew calendar is the product of evolution, including a Babylonian influence, when to add it was based on observation of natural agriculture-related events in Israel. Through the Amoraic period and into the Geonic period, this system was displaced by the mathematical rules used today. The principles and rules were codified by Maimonides in the Mishneh Torah in the 12th century. Maimonides work also replaced counting years since the destruction of the Temple with the modern creation-era Anno Mundi, the era used since the Middle Ages is the Anno Mundi epoch. As with Anno Domini, the words or abbreviation for Anno Mundi for the era should properly precede the date rather than follow it, AM5777 began at sunset on 2 October 2016 and will end at sunset on 20 September 2017. The Jewish day is of no fixed length, the Jewish day is modeled on the reference to. there was evening and there was morning. In the creation account in the first chapter of Genesis, based on the classic rabbinic interpretation of this text, a day in the rabbinic Hebrew calendar runs from sunset to the next sunset. In most populated parts of the world this is always approximately 24 standard hours, halachically, a day ends and a new one starts when three stars are visible in the sky. The time between sunset and the time when the three stars are visible is known as bein hashmashot, and there are differences of opinion as to which day it falls into for some uses. This may be relevant, for example, in determining the date of birth of a child born during that gap, there is no clock in the Jewish scheme, so that the local civil clock is used. The civil clock is used only as a reference point – in expressions such as, Shabbat starts at. In Judaism, an hour is defined as 1/12 of the time from sunrise to sunset, so, during the winter, an hour can be less than 60 minutes. This proportional hour is known as a shaah zmanit, a Jewish hour is divided into 1080 halakim or parts. A part is 3⅓ seconds or 1/18 minute, the ultimate ancestor of the helek was a small Babylonian time period called a barleycorn, itself equal to 1/72 of a Babylonian time degree. These measures are not generally used for everyday purposes, instead of the international date line convention, there are varying opinions as to where the day changes. One opinion uses the antimeridian of Jerusalem, the weekdays start with Sunday and proceed to Saturday, Shabbat

Hindu calendar
–
Hindu calendar is a collective term for the various lunisolar calendars traditionally used in Hinduism. They adopt a similar underlying concept for timekeeping, but differ in their emphasis to moon cycle or the sun cycle, the names of months. A Hindu calendar is referred to as Panchanga. The ancient Hindu calendar is similar in design to the Jewish calendar. Early Buddhist communities of India adopted the ancient Indian calendar, later Vikrami calendar, Buddhist festivals continue to be scheduled according to a lunar system. The Buddhist calendar and the traditional calendars of Cambodia, Laos, Myanmar, Sri Lanka. Similarly, the ancient Jainism traditions have followed the lunisolar system as the Hindu calendar for festivals, texts. However, the Buddhist and Jaina timekeeping systems have attempted to use the Buddha, the Hindu calendar is also important to the practice of Hindu astrology and zodiac system, most of which it adopted from Greece, in centuries after the arrival of Alexander the Great. The Indian national calendar or Saka calendar was introduced in 1952 based on the traditional Hindu calendars and this study was one of the six ancient Vedangas, or ancillary science connected with the Vedas – the scriptures of Hinduism. The ancient Indian culture developed a time keeping methodology and calendars for Vedic rituals. David Pingree has proposed that the field of timekeeping in Jyotisha may have derived from Mesopotamia during the Achaemenid period. Ohashi states that this Vedanga field developed from actual astronomical studies in ancient India, timekeeping as well as the nature of solar and moon movements are mentioned in Vedic texts. For example, Kaushitaki Brahmana chapter 19.3 mentions the shift in the location of the sun towards north for 6 months. The Vikrami calendar is named after king Vikramaditya and starts in 57 BCE, Hindu scholars attempted to keep time by observing and calculating the cycles of sun, moon and the planets. These texts present Surya and various planets and estimate the characteristics of the respective planetary motion, other texts such as Surya Siddhanta dated to have been complete sometime between the 5th century and 10th century present their chapters on various planets with deity mythologies. The manuscripts of texts exist in slightly different versions, present Surya- and planets-based calculation. These vary in their data, suggesting that the text were open and they tracked the solar year by observing the entrance and departure of surya in the constellation formed by stars in the sky, which they divided into 12 intervals of 30 degrees each. Like other ancient human cultures, Hindus innovated a number of systems of which intercalary months became most used, as their calendar keeping and astronomical observations became more sophisticated, the Hindu calendar became more sophisticated with complex rules and greater accuracy

Kali Yuga
–
Kali Yuga is the last of the four stages the world goes through as part of the cycle of yugas described in the Sanskrit scriptures, within the present Mahayuga. The other ages are called Satya Yuga, Treta Yuga, Kali Yuga is associated with the demon Kali. The Kali of Kali Yuga means strife, discord, quarrel or contention, according to Puranic sources, Krishnas departure marks the end of Dvapara Yuga and the start of Kali Yuga, which is dated to 17/18 February 3102 BCE. According to the Surya Siddhanta, Kali Yuga began at midnight on 18 February 3102 BCE and this is also considered the date on which Lord Krishna left the earth to return to his heavenly abode. This information is placed at the temple of Bhalka, the place of this incident, according to the astronomer and mathematician Aryabhatta the Kali Yuga started in 3102 BCE. He finished his book “Aryabhattiya” in 499 CE, in which he gives the year of the beginning of Kali Yuga. He writes that he wrote the book in the year 3600 of the Kali Age at the age of 23. As it was the 3600th year of the Kali Age when he was 23 years old, and given that Aryabhatta was born in 476 CE, according to KD Abhyankar, the starting point of Kaliyuga is an extremely rare planetary alignment, which is depicted in the Mohenjo-Daro seals. Going by this alignment the year 3102 BCE is slightly off, the actual date for this alignment is February 7 of 3104 BCE. There is also sufficient proof to believe that Vrdhha Garga knew of precession at least by 500 BCE, Garga had calculated the rate of precession to within 30% of what the modern scholars estimate. The Kali Yuga is thought by some authors to last 6480 years although other durations have been proposed, hindus believe that human civilization degenerates spiritually during the Kali Yuga, which is referred to as the Dark Age because in it people are as far away as possible from God. Hinduism often symbolically represents morality as an indian bull, in Satya Yuga, the first stage of development, the bull has four legs, but in each age morality is reduced by one quarter. By the age of Kali, morality is reduced to only a quarter of that of the golden age, the Mahabharata War and the decimation of Kauravas thus happened at the Yuga-Sandhi, the point of transition from one yuga to another. A discourse by Markandeya in the Mahabharata identifies some of the attributes of Kali Yuga, in relation to rulers, it lists, Rulers will become unreasonable, they will levy taxes unfairly. Rulers will no longer see it as their duty to promote spirituality, or to protect their subjects, people will start migrating, seeking countries where wheat and barley form the staple food source. (Srimad-Bhagavatam With regard to relationships, Markandeyas discourse says, Avarice. Humans will openly display animosity towards each other, people will have thoughts of murder with no justification and will see nothing wrong in that. Lust will be viewed as acceptable and sexual intercourse will be seen as the central requirement of life

Chinese calendar

The months begin on the day with the dark moon, the years begin with the dark moon near the midpoint between winter solstice and spring equinox. The solar terms are the important components of the Chinese calendar, in a month, there are one to three solar terms. The currently used traditional Chinese calendar is the end result of centuries of evolution, many astronomical and seasonal factors were added by ancient scientists, and people can reckon the date of natural phenomena such as the moon phase and tide upon the Chinese calendar. The Chinese calendar has over 100 variants, whose characteristics reflect the evolutionary path. As with Chinese characters, different variants are used in different parts of the Chinese cultural sphere, calendars in Mongolia and Tibet have absorbed elements from the Chinese calendar and elements from other systems, but they are not direct descendants of the Chinese calendar. The official calendar in China is the Gregorian calendar, but the traditional Chinese calendar still plays an important role there. The Chinese calendar is known officially as the Rural Calendar, but is referred to by other names, such as the Former Calendar.
