Daily Ancestoraetatis
Aetatis is Latin for "of age" or "aged": aetatis 63 on a gravestone or in a burial entry gives the person's age at death.
Aetatis is a form of the Latin word for age. On gravestones and in burial entries it introduces the age at death, often shortened to aet. or aetat. Longer forms include aetatis suae, of his or her age.
Some inscriptions say anno aetatis suae followed by a number, in the year of his or her age. Strictly, anno aetatis 63 means in the 63rd year, that is, aged 62, but carvers did not always use it strictly, so check birth or baptism records before calculating a birth year.
