Elizabeth I of England
Elizabeth I was Queen of England and Ireland from 17 November 1558 until her death on 24 March 1603. Sometimes called The Virgin Queen, Gloriana or Good Queen Bess, Elizabeth was the last of the five monarchs of the House of Tudor. Elizabeth was the daughter of Henry VIII and Anne Boleyn, his second wife, executed two-and-a-half years after Elizabeth's birth. Anne's marriage to Henry VIII was annulled, Elizabeth was declared illegitimate, her half-brother, Edward VI, ruled until his death in 1553, bequeathing the crown to Lady Jane Grey and ignoring the claims of his two half-sisters and the Roman Catholic Mary, in spite of statute law to the contrary. Edward's will was set aside and Mary became queen, deposing Lady Jane Grey. During Mary's reign, Elizabeth was imprisoned for nearly a year on suspicion of supporting Protestant rebels. In 1558 upon Mary's death, Elizabeth succeeded her half-sister to the throne and set out to rule by good counsel, she depended on a group of trusted advisers, led by William Cecil, 1st Baron Burghley.
One of her first actions as queen was the establishment of an English Protestant church, of which she became the Supreme Governor. This Elizabethan Religious Settlement was to evolve into the Church of England, it was expected that Elizabeth would produce an heir. She was succeeded by her first cousin twice removed, James VI of Scotland, she had earlier been responsible for the imprisonment and execution of James's mother, Queen of Scots. In government, Elizabeth was more moderate. One of her mottoes was "video et taceo". In religion, she was tolerant and avoided systematic persecution. After the pope declared her illegitimate in 1570 and released her subjects from obedience to her, several conspiracies threatened her life, all of which were defeated with the help of her ministers' secret service. Elizabeth was cautious in foreign affairs, manoeuvring between the major powers of Spain, she only half-heartedly supported a number of ineffective, poorly resourced military campaigns in the Netherlands and Ireland.
By the mid-1580s, England could no longer avoid war with Spain. England's defeat of the Spanish Armada in 1588 associated Elizabeth with one of the greatest military victories in English history; as she grew older, Elizabeth became celebrated for her virginity. A cult grew around her, celebrated in the portraits and literature of the day. Elizabeth's reign became known as the Elizabethan era; the period is famous for the flourishing of English drama, led by playwrights such as William Shakespeare and Christopher Marlowe, for the seafaring prowess of English adventurers such as Francis Drake. Some historians depict Elizabeth as a short-tempered, sometimes indecisive ruler, who enjoyed more than her share of luck. Towards the end of her reign, a series of economic and military problems weakened her popularity. Elizabeth is acknowledged as a charismatic performer and a dogged survivor in an era when government was ramshackle and limited, when monarchs in neighbouring countries faced internal problems that jeopardised their thrones.
After the short reigns of her half-siblings, her 44 years on the throne provided welcome stability for the kingdom and helped forge a sense of national identity. Elizabeth was born at Greenwich Palace and was named after her grandmothers, Elizabeth of York and Elizabeth Howard, she was the second child of Henry VIII of England born in wedlock to survive infancy. Her mother was Anne Boleyn. At birth, Elizabeth was the heir presumptive to the throne of England, her older half-sister, had lost her position as a legitimate heir when Henry annulled his marriage to Mary's mother, Catherine of Aragon, to marry Anne, with the intent to sire a male heir and ensure the Tudor succession. She was baptised on 10 September 1533. A canopy was carried at the ceremony over the three-day old child by her uncle Viscount Rochford, Lord Hussey, Lord Thomas Howard, Lord Howard of Effingham. Elizabeth was two years and eight months old when her mother was beheaded on 19 May 1536, four months after Catherine of Aragon's death from natural causes.
Elizabeth was deprived of her place in the royal succession. Eleven days after Anne Boleyn's execution, Henry married Jane Seymour, who died shortly after the birth of their son, Edward, in 1537. From his birth, Edward was undisputed heir apparent to the throne. Elizabeth was placed in his household and carried the chrisom, or baptismal cloth, at his christening. Elizabeth's first governess, Margaret Bryan, wrote that she was "as toward a child and as gentle of conditions as I knew any in my life". Catherine Champernowne, better known by her married name of Catherine "Kat" Ashley, was appointed as Elizabeth's governess in 1537, she remained Elizabeth's friend until her death in 1565. Champernowne taught Elizabeth four languages: French, Flemish and Spanish. By the time William Grindal became her tutor in 1544, Elizabeth could write English and Italian. Under Grindal, a talented and skilful tutor, she progressed in French and Greek. After Grindal died in 1548, Elizabeth received her education under Roger Ascham, a sympathetic teacher who believed that learning should be engaging.
By the time her formal education ended in 1550, Elizabeth was one of the best educated women of her generation. At the end of her life, Elizabeth was believed to speak Welsh, Cornish and Irish in addition to the languages men
The 15th century was the century which spans the Julian years 1401 to 1500. In Europe, the 15th century is seen as the bridge between the Late Middle Ages, the Early Renaissance, the Early modern period. Many technological and cultural developments of the 15th century can in retrospect be seen as heralding the "European miracle" of the following centuries. In religious history, the Roman Papacy was split in two parts in Europe for decades, until the Council of Constance; 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. Constantinople, in what is today Turkey the capital of the Christian Byzantine Empire, falls to the emerging Muslim Ottoman Turks, marking the end of the tremendously influential Byzantine Empire and, for some historians, the end of the Middle Ages; the event forced Western Europeans to find a new trade route, adding further momentum to what was the beginning of the Age of Discovery, which would lead to the global mapping of the world.
Explorations by the Portuguese and Spanish led to European sightings of the Americas and the sea passage along Cape of Good Hope to India, in the last decade of the century. 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, while Johannes Gutenberg's invention of the mechanical movable type began the Printing Press. These two events played key roles in the development of the Renaissance; the Spanish Reconquista leads to the final fall of the Emirate of Granada by the end of the century, ending over seven centuries of Muslim rule and returning Spain back to Christian rulers. The Hundred Years' War end with a decisive French victory over the English in the Battle of Castillon. Financial troubles in England following the conflict results in the Wars of the Roses, a series of dynastic wars for the throne of England; the conflicts end with the defeat of Richard III by Henry VII at the Battle of Bosworth Field, establishing the Tudor dynasty in the part of the century.
In Asia, under the rule of the Yongle Emperor, who built the Forbidden City and commanded Zheng He to explore the world overseas, the Ming Dynasty's territory reached its pinnacle. Tamerlane established a major empire in the Middle East and Central Asia, in order to revive the Mongol Empire. In Africa, the spread of Islam leads to the destruction of the Christian kingdoms of Nubia, by the end of the century leaving only Alodia; the vast Mali Empire teeters on the brink of collapse, under pressure from the rising Songhai Empire.

The traditional China calendar, or Former Calendar, Traditional Calendar or Lunar Calendar, is a lunisolar calendar which reckons years and days according to astronomical phenomena. It is defined by GB/T 33661-2017, "Calculation and promulgation of the Chinese calendar", issued by the Standardisation Administration of China on 12 May 2017. Although modern day China uses the Gregorian calendar, the traditional Chinese calendar governs holidays in China and in overseas Chinese communities, it lists the dates of traditional Chinese holidays and guides people in selecting auspicious days for weddings, moving, or starting a business. Like Chinese characters, variants of this calendar are used in different parts of the Chinese cultural sphere. Korea and the Ryukyu Islands adopted the calendar, it evolved into Korean and Ryukyuan calendars; the main difference from the traditional Chinese calendar is the use of different meridians, which leads to some astronomical events—and calendar events based on them—falling on different dates.
The traditional Japanese calendar derived from the Chinese calendar, but its official use in Japan was abolished in 1873 as part of reforms after the Meiji Restoration. Calendars in Mongolia and Tibet have absorbed elements of the traditional Chinese calendar, but are not direct descendants of it. Days begin and end at midnight, months begin on the day of the new moon. Years begin on the second new moon after the winter solstice. Solar terms govern the end of each month. Written versions in ancient China included stems and branches of the year and the names of each month, including leap months as needed. Characters indicated whether a month was short; the traditional Chinese calendar was developed between 771 and 476 BC, during the Spring and Autumn period of the Eastern Zhou dynasty. Before the Zhou dynasty, solar calendars were used. One version of the solar calendar is the five-elements calendar. A 365-day year was divided into five phases of 73 days, with each phase corresponding to a Day 1 Wu Xing element.
A phase began followed by six 12-day weeks. Each phase consisted of two three-week months. Years began followed by a bǐngzǐ day and a 72-day fire phase. Other days were tracked using the Yellow River Map. Another version is a four-quarters calendar. Weeks were ten days long, with one month consisting of three weeks. A year had 12 months, with a ten-day week intercalated in summer as needed to keep up with the tropical year; the 10 Heavenly Stems and 12 Earthly Branches were used to mark days. A third version is the balanced calendar. A year was 365.25 days, a month was 29.5 days. After every 16th month, a half-month was intercalated. According to oracle bone records, the Shang dynasty calendar was a balanced calendar with 12 to 14 months in a year; the first lunisolar calendar was the Zhou calendar, introduced under the Zhou dynasty. This calendar set the beginning of the year at the day of the new moon before the winter solstice, it set the shàngyuán as the winter solstice of a dīngsì year, making the year it was introduced around 2,758,130.
Several competing lunisolar calendars were introduced by states fighting Zhou control during the Warring States period. The state of Lu issued its own Lu calendar. Jin issued the Xia calendar in AD 102, with a year beginning on the day of the new moon nearest the March equinox. Qin issued the Zhuanxu calendar, with a year beginning on the day of the new moon nearest the winter solstice. Song's Yin calendar began its year on the day of the new moon after the winter solstice; these calendars are known as the six ancient calendars, or quarter-remainder calendars, since all calculate a year as 365 1⁄4 days long. Months begin on the day of the new moon, a year has 12 or 13 months. Intercalary months are added to the end of the year; the Qiang and Dai calendars are modern versions of the Zhuanxu calendar, used by mountain peoples. After Qin Shi Huang unified China under the Qin dynasty in 221 BC, the Qin calendar was introduced, it followed most of the rules governing the Zhuanxu calendar, but the month order was that of the Xia calendar.
The intercalary month, known as the second Jiǔyuè, was placed at the end of the year. The Qin calendar was used into the Han dynasty. Emperor Wu of Han r. 141 – 87 BC introduced reforms halfway through his reign. His Taichu Calendar defined a solar year as 365 385⁄1539 days, the lunar month was 29 43⁄81 days; this calendar introduced the 24 solar terms. Solar terms were paired, with the 12 combined periods known as climate terms; the first solar term of the period was known as a pre-climate, the second was a mid-climate. Months were named for the mid-climat
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.

The Buddhist calendar is a set of lunisolar calendars used in mainland Southeast Asian countries of Cambodia, Laos and Thailand as well as in Sri Lanka and Chinese populations of Malaysia and Singapore for religious or official occasions. While the calendars share a common lineage, they have minor but important variations such as intercalation schedules, month names and numbering, use of cycles, etc. In Thailand, the name Buddhist Era is a year numbering system shared by the traditional Thai lunisolar calendar and by the Thai solar calendar; the Southeast Asian lunisolar calendars are based on an older version of the Hindu calendar, which uses the sidereal year as the solar year. One major difference is that the Southeast Asian systems, unlike their Indian cousins, do not use apparent reckoning to stay in sync with the sidereal year. Instead, they employ their versions of the Metonic cycle. However, since the Metonic cycle is not accurate for sidereal years, the Southeast Asian calendar is drifting out of sync with the sidereal one day every 100 years.
Yet no coordinated structural reforms of the lunisolar calendar have been undertaken. Today, the traditional Buddhist lunisolar calendar is used for Theravada Buddhist festivals, no longer has the official calendar status anywhere; the Thai Buddhist Era, a renumbered Gregorian calendar, is the official calendar in Thailand. The calculation methodology of the current versions of Southeast Asian Buddhist calendars is based on that of the Burmese calendar, in use in various Southeast Asian kingdoms down to the 19th century under the names of Chula Sakarat and Jolak Sakaraj; the Burmese calendar in turn was based on the "original" Surya Siddhanta system of ancient India. One key difference with Indian systems is that the Burmese system has followed a variation of the Metonic cycle, it is unclear from where, how the Metonic system was introduced. The Burmese system, indeed the Southeast Asian systems, thus use a "strange" combination of sidereal years from Indian calendar in combination with the Metonic cycle better for tropical years.
In all Theravada traditions, the calendar's epochal year 0 date was the day in which the Buddha attained parinibbāna. However, not all traditions agree on when it took place. In Burmese Buddhist tradition, it was 13 May 544 BCE, but in Thailand, it was 11 March 545 BCE, the date which the current Thai lunisolar and solar calendars use as the epochal date. Yet, the Thai calendars for some reason have fixed the difference between their Buddhist Era numbering and the Christian/Common Era numbering at 543, which points to an epochal year of 544 BCE, not 545 BCE. In Myanmar, the difference between BE and CE can be 543 or 544 for CE dates, 544 or 543 for BCE dates, depending on the month of the Buddhist Era. In Sri Lanka, the difference between BE and CE is 544; the calendar recognizes two types of months: sidereal month. The Synodic months are used to compose the years while the 27 lunar sidereal days, alongside the 12 signs of the zodiac, are used for astrological calculations; the days of the month are counted in two halves and waning.
The 15th of the waxing is the civil full moon day. The civil new moon day is the last day of the month; because of the inaccuracy of the calendrical calculation systems, the mean and real New Moons coincide. The mean New Moon precedes the real New Moon; as the Synodic lunar month is 29.5 days, the calendar uses alternating months of 29 and 30 days. Various regional versions of Chula Sakarat/Burmese calendar existed across various regions of mainland Southeast Asia. Unlike Burmese systems, Lan Na, Lan Xang and Sukhothai systems refer to the months by numbers, not by names; this means reading ancient texts and inscriptions in Thailand requires constant vigilance, not just in making sure one is operating for the correct region, but for variations within regions itself when incursions cause a variation in practice. However, Cambodian month system, which begins with Margasirsa as the first month, demonstrated by the names and numbers; the Buddhist calendar is a lunisolar calendar in which the months are based on lunar months and years are based on solar years.
One of its primary objectives is to synchronize the lunar part with the solar part. The lunar months twelve of them, consist alternately of 29 days and 30 days, such that a normal lunar year will contain 354 days, as opposed to the solar year of ~365.25 days. Therefore, some form of addition to the lunar year is necessary; the overall basis for it is provided by cycles of 57 years. Eleven extra days are inserted in every 57 years, seven extra months of 30 days are inserted in every 19 years; this provides 20819 complete days to both calendars. This 57-year cycle would provide a mean year of about 365.2456 days and a mean month of about 29.530496 days, if not corrected. As such, the calendar adds an intercalary month in leap years and sometimes an intercalary day in great leap years; the intercalary month not only corrects the length of the year but corrects the accumulating error of the month to extent of half a day. The average length of the month is further corrected by adding a day to Nayon
