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. I have argued against this view of history in more than one previous post for example, this one about Britain and China in the 18th century.

To BCE or not to BCE? Common era of BC and AD appears to be over

Our calendar points to the birth of the most important human in history. AD stands for the years after Jesus Christ was born. BC stands for the years before the birth of Christ. There is no year zero, so there is only the year 1 BC followed by AD 1. By convention- here is how the years are said and written. BC always comes after the year, and AD comes before the year.

Should We Use BC/AD or BCE/CE for Dating Years? (B.C./A.D. or B.C.E./C.E.)

As abbreviations for Before the Common Era BCE and Common Era CE , they do not specifically privilege Christianity the criticism of using “BC” and “AD” and instead simply make reference to the fact that we are living in an era shared in common between Christianity and other religions—though Christianity and Judaism are the two religions usually in mind. Here are the facts. The tradition in the West is to base the count of our years around the alleged time when Jesus would have been born.

Dates can be expressed as AD, BC, BCE (before common era), and BP (before present). The accepted way to represent C ages is in terms of years BP.

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.

Muslims have a lunar calendar reckoned from A. The Jewish calendar is also a lunar one and is the official calendar of the State of Israel The Christian or Gregorian calendar has become the second calendar in most non-Christian countries, and as this is the Christian calendar, I cannot see why ‘before Christ’ and ‘in the year of Our Lord’ would be objectionable.

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

Anno Domini was the first of these to appear. This was supposedly in part a response to advice Diocletian received at the oracle of Apollo at Didyma. Previous to this, he had purportedly only advocated banning Christians from such things as the military and ruling body in hopes that would appease the gods. Afterward, he switched to an escalating policy of persecution to try to get Christians to worship the Roman gods. When this sort of thing was ineffective, they progressed to arresting and torturing Christians, starting with the leaders.

This method of convincing people to worship the Roman gods ended up being an amazing failure and the persecution appears to have only continued after AD in the Eastern half of the empire under Galerius and Maximinus.

Though there are a few frequently cited inflection points in that history—recorded instances of particular books using one system or another—the things that happened in the middle, and how and when new systems of dating were adopted, remain uncertain.
