What Does "AD 121" Mean?
"AD 121" stands for Anno Domini 121, which is Latin for "in the year of the Lord 121". This is a way of dating events in the Julian calendar, a system of timekeeping that was used in Europe for many centuries.
Here's a breakdown of what the components mean:
- AD: This abbreviation stands for Anno Domini, which is Latin for "in the year of the Lord". It is used to indicate years after the traditional year of Jesus Christ's birth.
- 121: This number represents the specific year in question.
Therefore, AD 121 refers to the year 121 years after the traditional year of Jesus Christ's birth according to the Julian calendar.
Note: The Julian calendar is no longer the primary calendar used in most parts of the world. It has been replaced by the Gregorian calendar, which is more accurate and accounts for the difference between the solar year and the calendar year.
The Gregorian calendar uses the same system of dating years as the Julian calendar, using "AD" to indicate years after the traditional year of Jesus Christ's birth. However, the years themselves are different due to the different calendar systems. For example, the year AD 121 in the Julian calendar corresponds to the year AD 121 in the Gregorian calendar.
