Bce Bc Difference. Web common era (ce) and before the common era (bce) are year notations for the gregorian calendar (and its predecessor, the julian calendar), the world's most widely used. While bc will be written after.
This is the same as the year ad 1 ( anno domini );. For example, allama iqbal was born in ad 1877. Ce stands for “common (or current) era”, while bce stands for “before the common (or current) era”.

While bc will be written after. The ad/bc notation does not use a year. Ad is awkward to use with centuries as opposed to specific dates—12th. 200 bc but ad 200.
