A decade is simply a time span of 10 years and a century a span of 100 years. The start dates of each are determined by how they are being used. The first decade of 21st century is 2000s I think that statement is where the problem lies. Strictly speaking it isn't true. Under the Gregorian calendar, the 21st Century started on January 1, 2001. The date ...

There was no announcement by the terrorists after 9/11 using that name nor taking ownership for the events (check me on that). The name "9/11", and the significance of the date, was given by the US media after the fact, something the terrorists could not have likely predicted. It doesn't follow the pattern of any of the previous big attacks on the US. We ...

I think we can narrow down your date-range to 1891-1903. According to the Directory of London Photographers, 1841-1908, by Michael Pritchard, Hermann Ernst's studio was only in St. Johns Wood between those dates. After that it moved to premises in Finchley Road, where it remained until after 1908 (the last date covered by the directory). His entry in the ...

A modern secondary historical paper or book should always use the Gregorian Calendar and the era of Exiguus. For pre-Gregory dates the proleptic calendar should be used. The reason for this is so that the exact distance between two dates can always be calculated easily and so that all books are using the same time scale so that dates in one book can easily ...

I know this would not be to OP's liking (considering his expressed opinion of Chinese history), but other people might find this interesting. The earliest event in Chinese history with a verifiable year is the Interregnum following the expulsion of King Li from the Zhou Kingdom. With the king exiled, his chief ministers ruled the realm in his stead. They ...

Le Cerf Volant, a 14-gun warship, was probably captured in late December 1668 (New Style date) by Edward Collier while commanding the Oxford. Collier seized the French ship at Cow island while it was anchored not far from Morgan's ship. According to Dudley Pope in Harry Morgan's Way: The Biography Of Sir Henry Morgan 1635-1688 (2013), Sir Thomas Modyford, ...

Most folks are used to positional numbers meaning they have a position to indicate the number of ones, the number of tens, the number of hundreds, and so on. The common Hindu-Arabic numerals are positional. "102" is one hundred plus zero tens plus two ones. You can see why a zero is necessary. Otherwise "12" could be "one hundred and two" or "ten and two (...

There are lots of documents in Sumerian and Akkadian with precise dates mentioned in the documents themselves. These go back well into the 3rd millennium BC. These can be converted without difficulty into Julian or Gregorian dates. But of course, all this depends on what you mean by “events”. If you include astronomical events visible on earth (eclipses, ...

The ancient state of Osroene did it earlier Regardless of the validity of the claim that Armenia became Christian in 301 AD, it isn't the first. Osroene - at the time a client state of the Roman Empire - formally adopted Christianity as the state religion under Abgar the Great in 201 AD. Looking first to the eastward, we find that in Edessa, the capital ...

Most likely Eusebius was dating Augustus' reign from the time he was named Consul and recognized as the son of Julius, in 44 BC, or from the power-sharing agreement made with Marc Antony in 43 BC. The later date you give corresponds to his assuming the title "Augustus" and the formal leadership of the Senate. This may technically be how the reign of "...

The short answer is we aren't sure. There are two basic methods that are commonly used to derive a birth year based on information from the Gospels. The first is the nativity accounts in Luke and Mathew. Both reference the reign of Herod the Great. Since he died in 4 BC, that means it couldn't possibly have been any later than then. The main issue with ...

As near as I can find, the Cour Volant was captured by Edward Collier in December 1668 at the Isle à la Vache, off the harbour of Aux Cayes in Hispaniola. Collier was, at that point commander of the frigate, Oxford, having been given command in early November 1668. The Oxford was blown up, and Collier took the newly named Satisfaction as his flagship in ...

A lot of crafted items can be reasonably dated by how they were made, and what they were made of. How readily available a given material (in this case, stone) is can be influenced by a lot of factors: trade, weather, societal conditions, affluence in different social tiers, etc. The item's time period of origin can be narrowed down by substances found in ...

You question is all over the place, it's difficult to understand what you are asking. Based on what you've stated in your question and in comments I am interpreting your question as being “when were the European equivalent of Arabic numbers used with a common era calendar system to write dates similar to how they are written now?” At the same time you ...

All our system of exact dating of events of ancient history is based on Babylonian astronomical observations. There is a large number of astronomical cuneiform tables found in Mesopotamia. Only in British Museum there are 20,000 of them. They are dated and contain various astronomical data (positions of the Moon, planets, eclipses etc.) which can be ...

The Treaty of Versailles was signed on June 28, 1919. November 11, 1918 was the date the armistice was in force; that day is now known as "Armistice Day" in many countries and "Veterans Day" in the United States. Hindenburg gave his "Stab in the Back" speech on November 18, 1919 which later became part of Hitler's rhetoric.

The order of months in a year does not change, neither does the order of days in a month. January in a particular year is always before December in the same year. So, for your example, 25 January 500 BCE is earlier than 25 December 500 BCE. As a more general point, it is worth writing historic dates out in full, rather than using numbers for months. To ...

(I'm not sure I've got an answer, but I've got some research that may help someone else find a better answer). The practice appears to be commonplace in European commercial and industrial applications. In commercial and industrial applications (delivery times, production plans, etc.), especially in Europe, it is often required to refer to a week of a ...

The base-10 Arabic number system you are using in your question also didn't exist back then. It couldn't have because, as you have noticed, the entire concept relies on having the concept of "0". The system was invented in India around 700 AD (not so coincidentally only about a generation after someone there discovered the concept of 0). A bit more than a ...

You're conflating mathematical precision with linguistic labeling. The first decade starts on January 1 of a year ending with a "0". The problem stems from the fact that when our dating system was created people commonly used the reigns of kings and leaders to describe events. We are now in the second year of the reign of Trump. In the 6th year of the ...

You are conflating the quantity or number zero, denoting none, with the numeral or symbol explicitly denoting the quantity of none, and represented in our Arabic Numeral system by '0' but also named zero. The significance of the symbol '0' is its utility as a placeholder when performing complex calculations on paper. Note that numeral systems prior to the ...

After performing some social media searches, I realized that Mr. Jamieson has a Facebook page. I have started a short dialog with him during which he has responded thusly: Me: "When did you perform in Poland in the 70's?" Ian: "Hi Chris, It all happened in 1986" Me: "By the way, the reason I asked was to answer a question asked here: Where ...

Recitals of the Rescript in education were abolished in 1946 with the enactment of the Fundamental Law of Education. Officially, resolutions to repeal the Rescript were passed by both houses on 19 June 1948. I used the Japanese Wikipedia as a quick source, which is reasonably accurate on such basic facts (though notorious for its lack of citations). More ...

Nabu-kudurri-usur (Nebuchadnezzar II), was the oldest son of Nabu-apla-usur (Nabopolassar), founder of the 11th dynasty of Babylon. From the records, we know that he was born c634BC and died c562BC (aged 71/72). He succeeded his father to become king c605BC. (the "c" in all these dates stands for "circa" or "about") You are right that we use a number of ...

Since Callicates was a 5th century BC philosopher, it would seemly likely she said it in the 5th century BC. Note that linguistic evidence cannot be used to date the author, because it is very likely the text was changed or emended at some point. For example, Stobaeus, the sole source for the quote, who was writing in the 5th century AD, many hundreds of ...

Without suggesting there is any documented evidence of a connection, 9/11 was also the date of another recent aerial attack on the downtown of a major Western city, Pinochet's 1973 coup in Santiago, Chile.

Don't know if Al Qaeda was conscious of it or not, but 11 September 1683 was the all-time high water mark of the advance of Muslim armies into Christendom, when the Ottoman Turks stood outside the walls of Vienna. They were defeated and driven back the following day, 12 September 1683. I also don't know if it is significant that 12 September is of course a ...
