the only thing i don't get is what event was so imporant the someone or some team of human being decided to begin counting years differently.

You are watching: Why bc years go backwards numerically

I'm conscious that the bear of christ is a possibility yet i'm feather for possible other answers due to the fact that Jesus is believed to it is in born from around 7-4 BC as result of the alignment that the regime of King Herod.

EDIT question was not worded really well; seemed favor a troll. But i'm actually trying to find answers.

Ok, based upon your various other comments, it sounds like what you are confused about is why AD/BC starts when it does, if Jesus was in fact born 4 BC or earlier. This is simply since Dionysius Exiguus who 'came up with' the advertisement system for numbering, miscalculated and also considered 1AD the year that Jesus birth. Actually, he doesn't rather say this, yet that was the expertise that emerged. But, as soon as this remained in place, and the mistake was made, it to be very challenging to change, which is why 'nothing in particular' occurred in 1AD.

Okay so it is just much easier to proceed with the present system than to bump all dates in background 4 years from what us know. Many thanks for the explanation. I'm off to research this Dionysius Exiguus guy to discover some more.

Not certain if troll, but I'll bite.

Let's say, you have a meeting at the doctor because of August 10th. Let's assume August 10th is the brand-new "zero".

August 12th will be 2 days due to the fact that the original date, for this reason it'll it is in "2 job after respectable 10th". August 13th will certainly be "3 days after respectable 10th" and also so on.

August 8th would certainly be "2 days prior to August 10th" and also August ninth would be "1 day prior to August 10th"

If we placed in order, it would certainly be (assuming B.A. Is "Before august 10th" and also A.A. Is "After august 10th): 2 B.A.; 1 B.A.; 0; 1 A.A.; 2 A.A. Etc

TL;DR: It's a an easy mathematics question. The bear of jesus is "year 1"

I recognize the math, thats not complex. I refuse to think that Jesus was born in year 0. Jesus was born under the reign of Herod witch lasted from about 37-4 BC. And also it's no that i don't recognize the mathematics or the counting down to the "year 0" what i don't understand is what exactly was the " year 0 " and who or what team thought it to be so crucial that they have to number all years the past and also future according to that one anchor point.

It is simple to assume that it is a christianity point to assume that the bear of jesus was the "0" top top the timeline and thus the church ordered that all dates prior to Jesus are merely a countdown come Jesus, favor the ticking time of a bomb, and also everything after Jesus, is simply a counting to see just how long that takes because that Jesus to come back.

Thats a pretty explanation the i've heard prior to but it simply feels so childish to me, there has to be some other hypothesis.
