AD

Alternative forms

 * (annō Dominī) A. D.
 * (annō Dominī) A. D.

Adverb

 * 1)   ; in the year of our Lord.

Usage notes

 * The initialism is used to specify numbered years counting from the once estimated birth of Christ in year 1.
 * The, as well as most house styles, requires placing AD before the number of the year and BC after, although in casual use either abbreviation can be found in either place. It is placed after centuries. It is often printed in small caps.
 * Some use CE, for "Common Era", which is more secular in nature, to avoid potential Christian bias.
 * "AD" is not normally used in expressions like "in the year AD 1990", since in such a year it is taken for granted (and it is also redundant, literally meaning "in the year in the year of our Lord 1990"). In "Vesuvius erupted in AD 79", it is expected.
