- Title: Chronological birthyear estimator
Abbrev: chronological estimator
Chronological age estimator based on child's birthdate minus 20-25 years (for females), minus 30-35 years (for males) or minus a set # of years in those cases where an ancestor's birth date is known & a descendants' birth date is known (i.e. if five generations are known to have elapsed in a 150 year time interval, then the estimator is used for each generation, every 30 years). Also used for societies where children generally did not accede to kingships, etc., ascension date minus 30 years. Also used based on a known spousal birthdate, i.e. -2-4 years for females, +2-4 years for males.
