In the history of Europe, this period is considered the part of the High Middle Ages. There was a decline of Byzantine power and rise of Norman domination over much of Europe. In Northern Italy, a growth of population in urban centers gave rise to early organized capitalism, in Ukraine, there was the golden age for the principality of Kievan Rus.

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

Henry I of England
–
Henry I, also known as Henry Beauclerc, was King of England from 1100 to his death. Henry was the son of William the Conqueror and was educated in Latin. On Williams death in 1087, Henrys elder brothers Robert Curthose and William Rufus inherited Normandy and England, respectively, Henry purchased the County of Cotentin in western Normandy from Robert, but William and Robert deposed him in 1091. Henry gradually rebuilt his power base in the Cotentin and allied himself with William against Robert, Henry was present when William died in a hunting accident in 1100, and he seized the English throne, promising at his coronation to correct many of Williams less popular policies. Henry married Matilda of Scotland but continued to have a number of mistresses. Robert, who invaded in 1101, disputed Henrys control of England, the peace was short-lived, and Henry invaded the Duchy of Normandy in 1105 and 1106, finally defeating Robert at the Battle of Tinchebray. Henry kept Robert imprisoned for the rest of his life, following Henrys victory at the Battle of Brémule, a favourable peace settlement was agreed with Louis in 1120. Considered by contemporaries to be a harsh but effective ruler, Henry skilfully manipulated the barons in England, Normandy was also governed through a growing system of justices and an exchequer. Many of the officials who ran Henrys system were new men of obscure backgrounds rather than families of high status. Henry encouraged ecclesiastical reform, but became embroiled in a dispute in 1101 with Archbishop Anselm of Canterbury. He supported the Cluniac order and played a role in the selection of the senior clergy in England. Henrys only legitimate son and heir, William Adelin, drowned in the White Ship disaster of 1120, Henry took a second wife, Adeliza, in the hope of having another son, but their marriage was childless. In response to this, Henry declared his daughter, Matilda, his heir, the relationship between Henry and the couple became strained, and fighting broke out along the border with Anjou. Henry died on 1 December 1135 after a week of illness, despite his plans for Matilda, the King was succeeded by his nephew, Stephen of Blois, resulting in a period of civil war known as the Anarchy. Henry was probably born in England in 1068, in either the summer or the last weeks of the year, possibly in the town of Selby in Yorkshire. His father was William the Conqueror, who had originally been the Duke of Normandy and then, following the invasion of 1066, became the King of England, the invasion had created an Anglo-Norman elite, many with estates spread across both sides of the English Channel. These Anglo-Norman barons typically had close links to the kingdom of France, Henrys mother, Matilda of Flanders, was the granddaughter of Robert II of France, and she probably named Henry after her uncle, King Henry I of France. Henry was the youngest of William and Matildas four sons, physically he resembled his older brothers Robert Curthose, Richard and William Rufus, being, as historian David Carpenter describes, short, stocky and barrel-chested, with black hair

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
