as the time line was splitted into two halves known as: B.C. (before christ) and A.D. (anno Domini) there was a confusion lead by some wrong calculation as to when was Jesus the Christ born. A.D. 1 started about a week later the Christ was born, and that was about 2000 years ago. there is no certain date to tell which was the actuall year when the Christ was born. To avoid this confusion, astronomers considered a point in the time line as a zero "0", referred to as the time when the christ was born. and started counting as A.D. 1, A.D. 2..as the years followed. and before that they counted as -1 B.C., -2 B.C... as we've studied in maths in number lines chapter. this counting down is done just to make calculations easier for the astronomers and others uses. there is no zero "0" year as such.

All times dating before AD are circa times; meaning that it is all ball park figures... it counts down to 1 AD which transitions to our present calendar 9 which also has had many adjustments). so basically... when we read time periods that are 5,000 BC means that whatever occured at that time it was approx. 5,000 years before actual collection of time... add that to our current year and that should give you an approximate age of when it existed...

In terms of "BC" years, 750 BC is 50 years after 800 BC because BC years count down from the year before, instead of up like we currendly do in AD. For example, if this year were 2009 BC, next year would be 2008 BC.

How do you count BC time?

To count BC time, you start from the specified year and count backwards to 1. For example, to count 5 BC years, you start from 5 BC and count down year by year until you reach 1 BC. Note that there is no year 0, so the progression goes from 1 BC directly to 1 AD.

In 2457 BC work gangs began quarrying at Tura For the next 14 years they ferried stone across the flooded valley In what year was the process completed?

BC means Before Christ. Intead of counting up the years like you do in AD (AD is what we count in now, e.g. 2001, 2002, 2003), you count backwards till you get 0 BC, which is when Christ was born. After 0 BC starts 1 AD then 2 AD etc. So basically, if you started in 2457 BC, and finished 14 years later, you would finish in 2443 BC.
