September 23 is the 266th day of the year(267th in leap years) in the Gregorian calendar.There are 99 days remaining until the end of the year. It is frequently the day of the autumnal equinox in the Northern Hemisphere and the day of the vernal equinox in the Southern Hemisphere.

A leap year is a calendar year containing one additional day added to keep the calendar year synchronized with the astronomical or seasonal year. Because seasons and astronomical events do not repeat in a whole number of days, calendars that have the same number of days in each year drift over time with respect to the event that the year is supposed to track. By inserting an additional day or month into the year, the drift can be corrected. A year that is not a leap year is called a common year.

The Gregorian calendar is the most widely used civil calendar in the world. It is named after Pope Gregory XIII, who introduced it in October 1582. The calendar spaces leap years to make the average year 365.2425 days long, approximating the 365.2422-day tropical year that is determined by the Earth's revolution around the Sun. The rule for leap years is:

Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the year 2000 is.

Autumn one of the Earths four temperate seasons, occurring between summer and winter

Autumn, also known as fall in American English and sometimes in Canadian English, is one of the four temperate seasons. Autumn marks the transition from summer to winter, in September or March, when the duration of daylight becomes noticeably shorter and the temperature cools down considerably. One of its main features is the shedding of leaves from deciduous trees.

Year 1122 (MCXXII) was a common year starting on Sunday of the Julian calendar.

Concordat of Worms agreement between Pope Calixtus II and Holy Roman Emperor Henry V on September 23, 1122 near the city of Worms

The Concordat of Worms, sometimes called the Pactum Calixtinum by papal historians, was an agreement between Pope Callixtus II and Henry V, Holy Roman Emperor on September 23, 1122, near the city of Worms. It brought to an end the first phase of the power struggle between the Papacy and the Holy Roman Emperors and has been interpreted as containing within itself the germ of nation-based sovereignty that would one day be confirmed in the Peace of Westphalia (1648). In part this was an unforeseen result of strategic maneuvering between the Church and the European sovereigns over political control within their domains. The King was recognised as having the right to invest bishops with secular authority in the territories they governed, but not with sacred authority. The result was that bishops owed allegiance in worldly matters both to the pope and to the king, for they were obliged to affirm the right of the sovereign to call upon them for military support, under his oath of fealty. Previous Holy Roman Emperors had thought it their right, granted by God, to name Church officials within their territories and to confirm the Papal election. In fact, the Emperors had been heavily relying on bishops for their secular administration, as they were not hereditary or quasi-hereditary nobility with family interests. A more immediate result of the Investiture struggle identified a proprietary right that adhered to sovereign territory, recognising the right of kings to income from the territory of a vacant diocese and a basis for justifiable taxation. These rights lay outside feudalism, which defined authority in a hierarchy of personal relations, with only a loose relation to territory. The pope emerged as a figure above and out of the direct control of the Holy Roman Emperor.


Year 1338 (MCCCXXXVIII) was a common year starting on Thursday of the Julian calendar.

Births

Year 63 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Cicero and Hybrida. The denomination 63 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Augustus First emperor of the Roman Empire

Augustus was a Roman statesman and military leader who was the first Emperor of the Roman Empire, controlling Imperial Rome from 27 BC until his death in AD 14. His status as the founder of the Roman Principate has consolidated an enduring legacy as one of the most effective and controversial leaders in human history. The reign of Augustus initiated an era of relative peace known as the Pax Romana. The Roman world was largely free from large-scale conflict for more than two centuries, despite continuous wars of imperial expansion on the Empire's frontiers and the year-long civil war known as the "Year of the Four Emperors" over the imperial succession.

Year 1158 (MCLVIII) was a common year starting on Wednesday of the Julian calendar.

Deaths

788 Year

Ælfwald I of Northumbria Northumbrian king

Kingdom of Northumbria Medieval kingdom of the Angles

The Kingdom of Northumbria was a medieval Anglian kingdom in what is now northern England and south-east Scotland. The name derives from the Old English Norþan-hymbre meaning "the people or province north of the Humber", which reflects the approximate southern limit to the kingdom's territory, the Humber Estuary. Northumbria started to consolidate into one kingdom in the early seventh century, when the two earlier core territories of Deira and Bernicia entered into a dynastic union. At its height, the kingdom extended from the Humber, Peak District and the River Mersey on the south to the Firth of Forth on the north. Northumbria ceased to be an independent kingdom in the mid-tenth century, though a rump Earldom of Bamburgh survived around Bernicia in the north, later to be absorbed into the mediaeval kingdoms of Scotland and England.
