Life and activity dates

Life dates are given after the entry name and title (if any). Dates are given wherever possible as years of birth and death. Where a date of birth is unknown, a year of baptism may be given instead, prefixed 'bap.'. If only a year of birth or of death is known, this is given alone, prefixed 'b.' or 'd.'. Years may be qualified by the addition of a question mark (meaning 'probably in the year given') or the prefix 'c.' (Latin circa: 'about', meaning 'about the year given: perhaps before and perhaps after'). Dates before the common era are labelled bc, and thereafter dates up to the year 100 are labelled ad. Other qualifiers (such as 'in or before') are self-explanatory.
A person's birth or death may not be datable to a single year. A solidus ('/') indicates alternative years: Ballantine, James (1807/8–1877). This form commonly occurs where there is evidence only of the subject's age at the time of another datable life event (for example, matriculation at university, marriage, or death). A multiplication sign indicates a range of years during which the subject may have been born or may have died: Baartman, Sara (1777x88–1815/16). Where a birth or death date cannot be more precisely fixed a decade date (late 1070s, early 1780s) may be provided.

Where neither a birth nor death date is known, dates are given of a person's known activity, prefixed by fl. (Latin floruit: 'flourished'). 'Flourished' dates may relate to activity in a single year or over a range of years. The same qualifications of year values may be used with 'flourished' dates as with birth and death dates: Smith, Theodore (fl. c.1765–c.1810x23). Where the person's activities cannot be dated more precisely, a century date is given. For a subject whose existence is highly doubtful or who is proven not to have existed, dates are prefixed by supp. ('supposedly').
