Question

why instead of BC or AS we add circa with some dates?​

Answer 1

Answer:

Often dates will be preceded with a "c." or a "ca." These are abbreviations of the Latin word "circa" which means around, or approximately. We use this before a date to indicate that we do not know exactly when something happened, so c. 400 B.C.E. means approximately 400 years Before the Common Era.
