The Holocene calender is a calender which deals with problems such as Year 0 and also with the problems of having a year system based on a religion.

In this calender, we are currently in the year 12,009 H.E. (Holocene or Human Era). The staring point is c. 10,000 B.C. as this is believed to be the start of human civilization.

In order to convert a year to H.E., you add 10,000 to an A.D. year, or subtract 10,001 for a B.C. year.

One advantage to this system is that if all computers convert to this system, it will solve the forthcoming Y10K problem centuries in advance.

It does seem to fall pretty much on simply guesstimating a round figure of 10,000 years before a date based on a religious calendar. I'd probably give it more credence if it was based on an archaelogical finding that can be dated.

How about having a calendar based on observed sky events; such as Haley's Comet; which have been recorded in contemporary documents. Best known example is Haleys Comet depicted on Bayeux Tapestry (except it is neither a document nor a tapestry - but Hey!). Novae can be backdated pretty accurately.

It is based on dateable finds, of a sort. The Holocene is defined as beginning at the end of the last Ice Age, so there are various bits of geological and environmental evidence with which that starting point may be dated. But, it not being a neat, single event, any neat single date used for calendrical purposes will necessarily be something of an approximation, certainly.

But it still uses the Christian calendar to give an exact date though.

The point CB27 makes is one that I have to agree with - yes, you're using a start point that you can date more effectively, but since that start date is in turn defined by referring to the existing calendar, what is the point?
And surely the point of a calendar is to give a methodical way of measuring time - which makes the idea of using as a starting point something which we're unable to give a precise date under our existing calendar seem odd. At least, that is what it feels like to me.

Can't we just stick with the one we have? It's worked for two thousand and nine years!

There are probably far more people in the world who use other calendars than "the one we have" though.

Oh, and if we're being absolutely correct, it can be argued that the international calendar based on the Christian calendar has only been around for a little over 400 years.

That's still longer than this one. And I'll be buggered if I'm going to write 12,009.

Time didn't exist before I was born, time won't exist after I die.

Why don't we just adopt "this year" as year zero permenantly - and then have every other year as the difference from this year.

The book industry would have a great time, reprinting everything each year to correct the dates.

We could push the envelope and always have today as the 1st of January Year zero?

The printing presses would simply go mad!!

I'm sorry if this is a stupid question but do all computers work on the "christian" calendar?
I wondered about this when watching some repeat programme or other where comments were made about the "millenium bug" Do countries and cultures with different calendars use them on their computers?

Nope - I think year zero is 1 Jan 1900 or something. I guess it depends on the application you're using at the time.

In my head now China will have a problem when they go through a thousand cycles of their animals. It could be called the millenium cat.
