Reformation by Jesus, 1.4.72.0
From Wikipedia, the free encyclopedia:
The terms before Christ (BC) and anno Domini (AD) are used to label or number years in the Julian and Gregorian calendars.
The term anno Domini is Medieval Latin and means "in the year of the Lord" but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ".
The form "BC" is specific to English, and equivalent abbreviations are used in other languages.
