Please explain my confused me like I’m 5 (0r 4 or 6).
Yes. They skipped right over. It confused many people at the time: a whole year of their lives, gone. Many centuries later when zero was invented, an explanation was finally offered as to why that happened.
😂
Nope. 1 BC/BCE -> 1 AD/CE. That’s just how it was designed.
https://en.wikipedia.org/wiki/Year_zero
The year of Jesus’ supposed birth was counted as year 1 AD/CE. The year before that is considered year 1 BC/BCE. It’s worth noting that the concept of zero didn’t yet exist back then. https://en.wikipedia.org/wiki/0#History
Probably worth noting that the Gregorian Calendar was an invention of the 16th Century. It was invented to deal with the problems of the Julian Calendar and the creators would have had a firm understanding of the concept of zero. The AD/BC split was all about the assumed year of the birth of Jesus of Nazareth (according to Christian mythology). The year of his birth was set as the first year Anno Domini or “The year of the Lord”. Or the first year where Jesus was kicking about. The year prior to that would therefore be the first year before “Before Christ” was alive, and therefore the year 1 BC.
The switch to the current system of using the theoretical birth of Jesus as the start of our calendar occurred in the 6th century, 500 years after the fact. They picked a year based on what evidence they had for when the birth of Jesus occurred with a margin of error of about ~30 years.
When this occurred and we started observing years in Anno Domini, whatever local calendar was being used was immediately replaced by the year 525, and retroactively everything before that was assigned it’s proper year. This ends with AD 1 and directly starts with BC 1 going the other direction. No year 0 was observed in this switch.Also note that before this switch, years were often designated in relation to the founding of a city or by the start of a ruler’s reign. There were always ordinal numbers, so the first year of a reign would be year 1, and there was never a zero, because it was year X of a previous reign.
Arbitrary decision is arbitrary.
The anno domini (AD) dating system started in 525. The concept of zero did not make it to Europe until the 11th century.
No, in our calendar system there was year 1 BC followed by year 1 AD. So no zero. It’s just how they set it up, they’re human made ideas anyway. Many countries do not even use this system, for example it is currently year 2567 in Thailand and year 113 in North Korea.
They left out 0 from the list. It basically jumps from -1 to 1.

Okay then.
Before dawn of technology advancements that we have today, people did stuff in a very different manner, for the sake of this explanation, I will call it “primitive”
As brilliant as human beings are, they often forget little things (little because may not have higher priority at that particular time) and dates is one of them.
Even now, if you happen to forget today’s date, and do not have means for referring that (like looking at your smartphone or watch, some digital billboards and whatnot),
what you would naturally do is refer back/forward, to the closest (recent/upcoming) date and day where a memorable event occurred/will occur. Events like your cousin’s birthday, trump impeachment, the coming football derby or the coming elections date. then you start counting with your fingers towards/backwards to the current day. This is “primitive”
These variations of calendars that currently exist today have their own sort of “memorable event”.
The most widely used today is AFTER CHRIST (AD). (Of which, to go back past that, they should have used count backwards tactic, i.e. -1, -2, -3, -4; Eg: -4AD; but instead, -4AD becomes 4BC which is BEFORE CHRIST. That is why counting forwards in BC, number decreases 😏 )
To answer your question;
“Year zero” is the year where that particular memorable event occurred.
But as I demonstrated above, we use that year as a reference to count forward/backwards the following/past years.
