AD (CE) and BC (BCE)

1. BC means before Christ, means before Jesus was born.
2. AD means Anno Domini, year of our Lord in Latin.
3. BCE means before the common era, its the same as BC, for non-Christians.
4. CE means common era, its the same as the AD, for non-Christians.
5. From 1st January 1BC to 1st January AD1 is exactly 1 year.
6. We put BC after the year, like 2000 BC and we put an AD before the year, as in AD 2000.
