I was looking at a small video clip we put up on You Tube the other day. This shows the world maps on our TimeMap of World History running quickly in sequence, giving a very raw, unscripted whistle-stop overview of world history. What interested me was the comments people had posted about it. I doubt whether most British history teachers have either. I can truly understand what its proponents are trying to do. Even to someone like myself, a committed and practising Christian, this is problematic.

Keeping Time: The Origin of B.C. & A.D.

The proposal caused consternation among Christian traditionalists and some of the corporation’s most famous names, who promised to ignore the idea. If you saw a date reference followed by the letters BC , you’d be likely to know that whatever was being described happened a jolly long time ago. But if you saw one preceded or followed by the letters CE , would you be clear about its position in the sequence of time?

For the uninitiated, CE is an abbreviation of the expression Common Era , and in , it’s proving rather controversial. CE and BCE … were conceived as … expressions that are not specifically anchored in Christianity and are therefore sensitive to all and any of the world’s religions and belief systems.

When comparing historical dates, it’s important to note that the Gregorian calendar, used universally today in Western countries and in international commerce, was adopted at different times by different countries. Britain and her colonies including what is now the United States , did not switch to the Gregorian calendar until , when Wednesday 2nd September in the Julian calendar dawned as Thursday the 14th in the Gregorian.

The Gregorian calendar is a minor correction to the Julian. In the Julian calendar every fourth year is a leap year in which February has 29, not 28 days, but in the Gregorian, years divisible by are not leap years unless they are also divisible by How prescient was Pope Gregory!

We analysed sediment from a latrine dating to the early s for the presence of helminth eggs and protozoan parasites which caused.

References to historical dates under either classification shouldn’t create confusion in a researcher’s mind. Identifying historical dates until that point was often a complicated proposition, since different historians worked under different calendars. Converting historical dates to the standard Gregorian calendar would not have been easy.

Using the birth of Jesus Christ as a central point made more sense to the religious historians. The term BC is short for “Before Christ. The time following the birth of Christ was now referred to as the “Vulgar Era” in some circles. The meaning of the word vulgar actually meant ‘common’ at that time, not distasteful or obscene. Eventually many areas of the Western world adopted the less Christ-centered term “Common Era. Modern scholars believe the actual birth of Christ would fall around 7 to 4 BC, which renders the actual year of 1 AD relatively meaningless historically.

By the time he reformed the Julian calendar in using the observations of Christopher Clavius and Johannes Kepler , it had drifted 10 days off course. To this day, most of the world uses his Gregorian calendar. Ironically, by the time the Catholic church buckled under the weight of the scientific reasoning that pointed out the error, it had lost much of its power to implement the fix.

The “new” calendar, as we know it today, was not adopted uniformly across Europe until well into the 18th century. In some ways, yes. When Julius Caesar introduced his calendar in 45 B.

Common Era CE is one of the notation systems for the world’s most widely used calendar era. The year-numbering system used by the Gregorian calendar is used throughout the world today, and is an international standard for civil calendars. The expression has been traced back to , when it first appeared in a book by Johannes Kepler as the Latin annus aerae nostrae vulgaris , [5] [6] and to in English as ” Vulgar [b] Era”. The term “Common Era” can be found in English as early as , [7] and became more widely used in the midth century by Jewish religious scholars.

In the later 20th century, the use of CE and BCE was popularized in academic and scientific publications as a culturally neutral term. It is also used by some authors and publishers who wish to emphasize sensitivity to non-Christians by not explicitly referencing Jesus as ” Christ ” and Dominus “Lord” through use of the abbreviation [c] “AD”.

Writing About History

With some rather heated debate, authors, pundits, scholars, and literary style masters took one side over the other. Decades later, they remain split, but the consensus seems to be that the decision to use one or the other is a personal or organizational preference. The same applies to the use of periods: use or don’t use them, based on personal or organizational preference. Both take as their starting point the year when 4th-century Christian scholars believed Jesus Christ was born, designated as AD 1 or 1 CE.

The designation of a particular year in either set has identical values. In other words, today Jesus is believed to have been born somewhere between 4 and 7 BCE, which is equivalent to 4 and 7 BC.

The idea of counting years has been around for as long as we have written records, but the idea of syncing up where everyone starts counting is relatively new. Many publications use “C. In the early Middle Ages, the most important calculation, and thus one of the main motivations for the European study of mathematics, was the problem of when to celebrate Easter. The First Council of Nicaea , in A. Computus Latin for computation was the procedure for calculating this most important date, and the computations were set forth in documents known as Easter tables.

It was on one such table that, in A. Dionysius devised his system to replace the Diocletian system, named after the 51st emperor of Rome, who ruled from A. Dionysius never said how he determined the date of Jesus’ birth, but some authors theorize that he used current beliefs about cosmology, planetary conjunctions and the precession of equinoxes to calculate the date. Dionysius attempted to set A.

The addition of the B. There was no year zero. However, zero did exist; our modern conception of zero was first published in A.

Understanding Historical Dating: BC, AD, CE, BCE, Circa, Historic, Historical

The continuing use of AD and BC is not only factually wrong but also offensive to many who are not Christians. What year is it? This most basic of historical questions yields no universal answer. For Orthodox Jews, counting from the putative creation of the universe, the October issue of History Today , where this article first appeared, was published Anno Mundi According to the Muslim lunar calendar, dating from Muhammad’s Hijra flight or emigration from Mecca, it is now ah Persians, Mayans, Jains, even Freemasons, all have their own eras.

Writers would use that date as a reference point. Roman consular dating prevailed in the West until the year CE when the Emperor Justinian I stopped​.

It is logical, with the biggest denominators being listed first the same way as numbers, times and weights are , making it easily sortable and utterly clear. The International Organization for Standardization specification for the International Date Format is the ISO format, adopted so far by the computer industry in general due to the advantages of sorting by dates in filenames , United Nations, commerce groups, scientific communities and some Western governments, although most individuals generally continue to use culture-specific date formats.

The full standard runs to a heady length of 33 pages. Wouldn’t it be wonderful if there were an internationally agreed standard? Well, there is. It follows conventions of scale where the biggest denominators come first i. Most have now done so” [Galpin ]. I have been using the YYYY MMM DD format since late when the Millennium Bug started to hit the news; I came up with the format independently of the International Organization for Standardization after thinking on what would make a good, universal, systematic date format that would be completely non-ambiguous.

Conversion Converting dates in the calendar we use into Roman dates is tricky and involves some degree of compromise. The Roman calendar was altered many times as errors in previous calendars were corrected and political considerations led to compromises in those changes. So whether it is the day, the month or the year we convert into ‘Roman’ the final result may end up overall as something a Roman would not recognise.

‘CE’ means Common Era, or Current Era. ‘CE’ is equivalent to ‘AD’ as a date and places the ‘common’ or ‘current’ era as being from the.

In almost all archaeology books and articles the authors use dates. This is the Christian era in the Gregorian calendar, starting from 1 AD as the year in which Christ was believed to have been born. The date was calculated about years after the event, so was a broad estimate. If lower case letters are used, this often means that the date is based on an uncalibrated radiocarbon date see below for date calibrations.

Battle of Hastings was in CE. First used almost years ago, it has become especially popular from the late twentieth century to emphasise secularism or sensitivity to non-Christians. This signifies the pre-Christian era in the Gregorian calendar. This runs backwards from 1 BC. The use of BP by archaeologists, geologists, and other scientists, refers to radiocarbon ages and results from other radiometric dating techniques. Radiometric dating techniques are those that provide absolute dates based on the decay of radioactive isotopes.
