- AD (Anno Domini):
- Meaning: Latin for “in the year of our Lord.”
- Usage: Refers to years after the birth of Jesus Christ.
Example: The year 2023 AD indicates 2023 years after Christ’s birth.
BC (Before Christ):
- Meaning: Indicates the years before the birth of Jesus Christ.
- Usage: Counts backwards from 1 BC, with no year 0.

Key Points to Remember:
– The Gregorian calendar uses AD and BC to denote time.
– AD is used for years following Christ’s birth, while BC is for years prior.
– The system was developed in the 6th century by Dionysius Exiguus, a monk.
Modern Alternatives:
– CE (Common Era): Equivalent to AD; used in secular contexts.
– BCE (Before Common Era): Equivalent to BC; provides a non-religious nomenclature.
This understanding of AD and BC is crucial for historical studies, timelines, and chronological references in various fields.
