Anno Domini (abbreviated as AD or A.D.) and Before Christ (abbreviated as BC or B.C.) are designations used to label or number years used with the Julian and Gregorian calendars. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus of Nazareth, with AD counting years after the start of this epoch, and BC denoting years before the start of the epoch. There is no year zero in this scheme, so the year AD 1 immediately follows the year 1 BC. This dating system was devised in 525, but was not widely used until after 800.
Alternative names for this era include vulgaris aerae (found 1615 in Latin), "Vulgar Era" (in English, as early as 1635), "Christian Era" (in English, in 1652), "Common Era" (in English, 1708), and "Current Era". Since 1856, the alternative abbreviations CE and BCE are sometimes used in place of AD and BC.
The Gregorian calendar is the most widely used calendar in the world today. For decades, it has been the unofficial global standard, adopted for pragmatic interests of international communication, transportation and commercial integration and recognized by international institutions such as the United Nations and the Universal Postal Union.
Dropped from the sky.
Came to earth.
To clean your minds.
And serve your hate.
Say your prayers.
Bring your child.
Save your souls.
I know what you've done.
You try to rule our lives.
You want to gain control.
You use a son of God.
To bring this hate.
You blind us with his name.
You treat us like a game.
