How do you calculate a how old something with a date of BC? ie 2,600 BC is that 4,607 years old? 2,600 + 2007?

Answer 1

Yes

Answer 2

Yes, a date of 2600 would mean as you say, but how to calculate how old something is, is different. For example if we need to know how old a tree is, the rings is what we use, or if we found a skull or something, the scientists would use a different method. It is more complicated than the space her would allow.

Answer 3

You're right.

Some people use BCE (Before the Current Era) or CE (In the Current Era) as a replacement for BC and AD in order to be considerate of others' feelings.
