What does the "c." mean in c.2500 b.c.?

In my son's history books when they refer to B.C. dates they add a "c." before the date. And I've seen the B.C. sometimes left our altogether. What does c. mean?

What does the "c." mean in c.2500 b.c.?
b.c means before christ





a.d means anno domini





b.c.e means before common era





c.e means common era
Reply:c in that context means "circa," or about--the exact date is not known.
Reply:It means circa or around. They do that because they don't know the exact year.
Reply:circa
Reply:B.C. MEANS BEFORE CHRIST
Reply:The c. means "circa" means "about" or around. It is used when the dates are approximately known.





So c.2500B.C.





Means approx 2500 years before Christ.





Hope This Helped ;)
Reply:The "c" stands for "circa" -- it's Latin for "around".
Reply:The letters that have CC mean the comin era.
Reply:circa which means "roughly"





it's used when the precise date isn't known.





the "c" in "b.c.", of course, means "Christ"
Reply:Christ
