AutumnAutumn, also known as fall in North American English, is one of the four temperate seasons on Earth. Outside the tropics, autumn marks the transition from summer to winter, in September (Northern Hemisphere) or March (Southern Hemisphere). Autumn is the season when the duration of daylight becomes noticeably shorter and the temperature cools considerably. Day length decreases and night length increases as the season progresses until the Winter Solstice in December (Northern Hemisphere) and June (Southern Hemisphere).
BedeBede (biːd Bǣda ˈbæːdɑ, Bēda ˈbeːdɑ; 672/3 - 26 May 735) was an English monk and an author and scholar. He was one of the greatest teachers and writers during the Early Middle Ages, and his most famous work, Ecclesiastical History of the English People, gained him the title "The Father of English History". He served at the monastery of St Peter and its companion monastery of St Paul in the Kingdom of Northumbria of the Angles. He is also known as Saint Bede, The Venerable Bede, and Bede the Venerable (Beda Venerabilis).
Shaka eraThe Shaka era (IAST: Śaka, Śāka) is a historical Hindu calendar era (year numbering), the epoch (its year zero) of which corresponds to Julian year 78. The era has been widely used in different regions of the Indian subcontinent as well as in Southeast Asia. According to the Government of India, it is referred as the Shalivahana Era (IAST: Śālivāhana). The origin of the Shaka era is highly controversial.
Attic calendarThe Attic calendar or Athenian calendar is the lunisolar calendar beginning in midsummer with the lunar month of Hekatombaion, in use in ancient Attica, the ancestral territory of the Athenian polis. It is sometimes called the Greek calendar because of Athens's cultural importance, but it is only one of many ancient Greek calendars. Although relatively abundant, the evidence for the Attic calendar is still patchy and often contested. As it was well known in Athens and of little use outside Attica, no contemporary source set out to describe the system as a whole.
Calendar dateA calendar date is a reference to a particular day represented within a calendar system. The calendar date allows the specific day to be identified. The number of days between two dates may be calculated. For example, "25 " is ten days after "15 ". The date of a particular event depends on the observed time zone. For example, the air attack on Pearl Harbor that began at 7:48 a.m. Hawaiian time on 7 December 1941 took place at 3:18 a.m. Japan Standard Time, 8 December in Japan.
Terrestrial TimeTerrestrial Time (TT) is a modern astronomical time standard defined by the International Astronomical Union, primarily for time-measurements of astronomical observations made from the surface of Earth. For example, the Astronomical Almanac uses TT for its tables of positions (ephemerides) of the Sun, Moon and planets as seen from Earth. In this role, TT continues Terrestrial Dynamical Time (TDT or TD), which succeeded ephemeris time (ET). TT shares the original purpose for which ET was designed, to be free of the irregularities in the rotation of Earth.
TishreiTishrei (ˈtɪʃreɪ) or Tishri (ˈtɪʃriː; tīšrē or tīšrī; from Akkadian tašrītu "beginning", from šurrû "to begin") is the first month of the civil year (which starts on 1 Tishrei) and the seventh month of the ecclesiastical year (which starts on 1 Nisan) in the Hebrew calendar. The name of the month is Babylonian. It is a month of 30 days. Tishrei usually occurs in September–October on the Gregorian calendar. In the Hebrew Bible the month is called Ethanim (אֵתָנִים – ), or simply the seventh month.
Julian year (astronomy)In astronomy, a Julian year (symbol: a or aj) is a unit of measurement of time defined as exactly 365.25 days of 86400 SI seconds each. The length of the Julian year is the average length of the year in the Julian calendar that was used in Western societies until the adoption of the Gregorian Calendar, and from which the unit is named. Nevertheless, because astronomical Julian years are measuring duration rather than designating dates, this Julian year does not correspond to years in the Julian calendar or any other calendar.
NundinaeThe nundinae (nənˈdɪnaɪ, -niː), sometimes anglicized to nundines, were the market days of the ancient Roman calendar, forming a kind of weekend including, for a certain period, rest from work for the ruling class (patricians). The nundinal cycle, market week, or 8-day week (nundinum or internundinum) was the cycle of days preceding and including each nundinae. These were marked on fasti using nundinal letters from A to H.
