If ISO stands for International Organization for Standardization shouldn't it be IOS?
Not in French.
A year zero makes absolutely no sense.
Yes it does. What doesn't make any sense is not having a year zero. And everyone who has to calculate with dates before and after the Common Era.
How many years are there between Jan 1, 1980 and Jan 1, 2000? 20 of course.
How many years are there between Jan 1, 100 BCE and Jan 1, 70 BCE? 30 of course.
Now how many years are there between Jan 1, 10 BCE and Jan 1, 10 CE?
Not having a year zero messes up calculations in astronomy and history.
Year 0 *doesn't* make sense though. The first year should be "Year 1"
Just because we have years before "the first year" doesn't mean the first year should be Year 0 for some reason. If anything it makes more sense to make Year 0 the year BEFORE the first year... but then that would mess up the whole B.C. scale
The BCE scale is already messed up, precisely because we don't have a year zero. That's why I propose we simply move all BCE dates one year back and include a year 0 before 1 CE.
Might as well just renumber the whole chronology from some point before the beginning of recorded history.
Yeah, sure. Or current years are just by tradition when Jesus was born, and are mislabeled as "Before Christ" and "Anno Domino", even though most scholars agree Jesus was probably born about 5 years before tradition.
As such labels are thus wrong, I prefer using "Before Common Era" and "Common Era" to address the years. And we need to include a year zero. E.g. Jesus was probably born in 4 BCE, and died in 30 CE, which means he was 35 years old at the time of his death.
As there is no point in holding with a tradition just because it is tradition - especially when tradition is most likely wrong - I am all for deciding on a new event to set as year zero.
Ideally, such an event should be old enough that most dates humans like to use are included in the positive range, but not so old as to make it useless (If we knew the exact year of the Big Bang, it should still not be used as writing todays year as 17,000,002,010 is quite ridiculous).
Somewhere at the beginning of human civilisation would be ideal I think, as that would bring all human history within the positive range. However, I don't know of any good event upon to declare the "start of human civilization".
I have been fiddling with ideas such as the first agriculture, or the construction of Stonehenge, or the founding of Jericho, etc. But none of those are a very distinct temporal event, and we don't have the exact dates for any of them.
We could of course say that we set year zero 15,000 years back, something that will allow us to include all of human history, but that is a very ugly hack, as it basically defines year zero as 15,000 years from some arbitrary year of today.
