Definition

1. Adverb:
   • In the Christian era; used before dates after the supposed year Christ was born: "A.D." is an abbreviation for the Latin phrase "Anno Domini," which means "in the year of the Lord." It is used to label or number years in the Julian and Gregorian calendars following the traditional year of the birth of Jesus Christ.

Usage

• Placement: "A.D." is traditionally placed the year number (e.g., A.D. 1066), though modern usage increasingly accepts it the year (e.g., 1066 A.D.).
• Context: It is used specifically for dates in the era after the calculated birth of Jesus. It is often contrasted with "B.C." (Before Christ).
• Style: It is typically written with periods (A.D.), though the form "AD" without periods is also common.

Examples

• Adverb:
  • The Roman Empire fell in A.D. 476.
  • This manuscript dates from around A.D. 800.
  • The tradition began in A.D. 33.

Advanced Usage

  • The city was founded in A.D. 1009.
• With Centuries: "A.D." can be used when referring to centuries within the Common Era.
