Understanding Calendar Notation: Difference between BC, BCE, AD and CE. A little bit about the birth of Jesus as well.
- This right here is a fresco birapheal of Plato hanging out with his best student Aristotle
- And you may or may not know that this two two fellow along with Plato's teacher Socrates
- who is considered the fathers of Western philosophy
- but that's not what this video is about
- This is actually just a small little video about different dates or
- a better way to think about it different ways to specify dates or dating machinisms
- and so if you were to look up Plato's birth you might get either 428 or 427
- but we'll go with 428
- if you were to look up Plato's birth
- you might see it written as 428 BC
- or you might see it written as 428 BCE
- and the natural question is, well, what's the difference here
- they both have BC but this one has an E and it's the same year right now
- And the answer is that these are referring to the exact same year
- but the in history but the ... here do stand for different things
- BC literally stands for Before Christ
- so the date is written 428 BC
- the implication is that this is 428 years before the birth of Christ
- We'll see in a second that that's not exactly right
- But that's what the implication is. But if someone writes BCE
- they're saying something very different. The B still stands for before.
- So the B still stands for Before. But the CE. The C in CE does not stand for Christ anymore. It now stands
- for Common. And so the CE part, the CE part is Common Era. Common Era.
- Even thogh it's not referring to Christ anymore and that is kind of the intention here
- so that it is less religious than the term Before Christ
- it is still kind of putting an importance on Christ's birth
- because it is saying that the Common Era is the time period after the birth of Christ
- which we'll see in a second isn't exactly right
- but it's essentially the same exact dating sheme.
- One with a -- not directly referring to Christ
- one that is directly referring to Christ.
- Similarly, this right here is a painting of Christopher Columbus
- and if you would look up in history books
- you'd know what was his first voyage
- and when did he first show up in the New World
- fighting an island in the Bahamas you would see it written as
- either 1492 or AD 1492
- or 1492 CE
- And once again these are all referring to the same year
- just using different
- one of them is a little bit more religious
- or more directly refers to Christ
- and one is a little less religious.
- So AD some people think it refers to After Death
- It does not refer to After Death.
- Because if you think about it if you have years before the Christ and
- if you start numbering years after his death how would you number the years during his life?
- So Ad does not stand for After Death.
- It stands for Anno -- Anno Domini.
- Which literally means -- Anno means year
- and Domini means Lord or the Lord or the year of our Lord
- one anno domini would be the year of Jesus Christ's birth
