What are suffixes AD and BC?

                              What are suffixes  AD and BC?

We have studied in history that the years are often referred as respective year then BC or AD. For example this year can be written as 2012 AD. But what these suffixes actually refer to?
Anno Domini (AD) and Before Christ (BC) are designations used to label or number years used with the Gregorian calender. This calender era is based on the birth of Jesus , with AD counting the years after the birth of Jesus and BC, denoting the years before.
There is no year zero in this scheme, so the year AD1 starts immediately after BC1. BC countdown starts backwardly like 99 BC, 98 BC.....1 AD, 2 AD .Since 1856, the alternative abbreviations CE and BCE are sometimes used in the place of AD and BC.
