Solar Calendar
A solar calendar is a calendar whose dates indicate the season or almost equivalently the apparent position of the Sun relative to the stars. The Gregorian calendar, widely accepted as a standard in the world, is an example of a solar calendar. The main other type of calendar is a lunar calendar, whose months correspond to cycles of Moon phases. The months of the Gregorian calendar do not correspond to cycles of the Moon phase. The Egyptians appear to have been the first to develop a solar calendar, using as a fixed point the annual sunrise reappearance of the Dog Star—Sirius, or Sothis—in the eastern sky, which coincided with the annual flooding of the Nile River. They constructed a calendar of 365 days, consisting of 12 months of 30 days each, with 5 days added at the year’s end. The Egyptians’ failure to account for the extra fraction of a day, however, caused their calendar to drift gradually into error. Examples The oldest solar calendars include the Julian calendar a ...

Mughal Empire
The Mughal Empire was an early-modern empire that controlled much of South Asia between the 16th and 19th centuries. Quote: "Although the first two Timurid emperors and many of their noblemen were recent migrants to the subcontinent, the dynasty and the empire itself became indisputably Indian. The interests and futures of all concerned were in India, not in ancestral homelands in the Middle East or Central Asia. Furthermore, the Mughal empire emerged from the Indian historical experience. It was the end product of a millennium of Muslim conquest, colonization, and state-building in the Indian subcontinent." For some two hundred years, the empire stretched from the outer fringes of the Indus river basin in the west, northern Afghanistan in the northwest, and Kashmir in the north, to the highlands of present-day Assam and Bangladesh in the east, and the uplands of the Deccan Plateau in South India. Quote: "The realm so defined and governed was a vast territory of some , rang ...

Hussain Shahi Dynasty
The Hussain Shahi dynasty ( bn, হোসেন শাহী খান্দান, fa, حسين شاهی خاندان) was a family which ruled the late medieval Sunni Muslim Sultanate of Bengal from 1494 to 1538. History The dynasty's founder, Alauddin Husain Shah, a descendant of Husayn ibn Ali, is considered as the greatest of all the sultans of Bengal for bringing a cultural renaissance during his reign. He conquered Kamrup-Kamata and Orissa and extended the Sultanate all the way to the port of Chittagong, which witnessed the arrival of the first Portuguese merchants. His supposed heir, Shahzada Danyal, who he had appointed as the governor of Kamata, was executed by rebellious chieftains in Assam. Husain Shah's son and successor, Nasiruddin Nasrat Shah, gave refuge to the Afghans during the invasion of Babur though he remained neutral. Known as the Akbar of Bengal, Nasrat was known by the Hindus of Bengal as Nripati Tilak and Jagatbhusan. He encouraged the translation of San ...

Alauddin Husain Shah
Ala-ud-din Husain Shah ( bn, আলাউদ্দিন হোসেন শাহ (1494–1519)Majumdar, R.C. (ed.) (2006). ''The Delhi Sultanate'', Mumbai: Bharatiya Vidya Bhavan, pp.215-20 was an independent late medieval Sultan of Bengal, who founded the Hussain Shahi dynasty. He became the ruler of Bengal after assassinating the Sultan, Shams-ud-Din Muzaffar Shah, whom he had served under as wazir. After his death in 1519, his son Nusrat Shah succeeded him. The reigns of Husain Shah and Nusrat Shah are generally regarded as the "golden age" of the Bengal sultanate. Origin and early life There are several opinions regarding the origin of Alauddin Husain Shah. According to a 1788 chronicle, ''Riyaz-us-Salatin'', Sayyid Husain Sharif Makki was the son of Sayyid Ashraf al-Husaini, a Sharif of Mecca, with ''al-Husaini'' suggesting descent from Husayn ibn Ali. An earlier work by Firishta also mentions Husain as a Sayyid and former inhabitant of Mecca. His father's name is backed u ...

Aryabhata
Aryabhata (ISO: ) or Aryabhata I (476–550 CE) was an Indian mathematician and astronomer of the classical age of Indian mathematics and Indian astronomy. He flourished in the Gupta Era and produced works such as the ''Aryabhatiya'' (which mentions that in 3600 ''Kali Yuga'', 499 CE, he was 23 years old) and the ''Arya-siddhanta.'' Aryabhata created a system of phonemic number notation in which numbers were represented by consonant-vowel monosyllables. Later commentators such as Brahmagupta divide his work into ''Ganita ("Mathematics"), Kalakriya ("Calculations on Time") and Golapada ("Spherical Astronomy")''. His pure mathematics discusses topics such as determination of square and cube roots, geometrical figures with their properties and mensuration, arithmetric progression problems on the shadow of the gnomon, quadratic equations, linear and indeterminate equations. Aryabhata calculated the value of pi (''π)'' to the fourth decimal digit and was likely aware that p ...

Sanskrit
Sanskrit (; attributively , ; nominally , , ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rig Veda, a colle ...

Surya
Surya (; sa, सूर्य, ) is the sun as well as the solar deity in Hinduism.
