birthdate calculation

Birthdate calculation involves determining an individual's date of birth based on known information, such as age or date of death. When the age is known, we subtract the age from the current date, accounting for whether the birthday has occurred this year, to find the birthdate. For historical figures or missing data, historians use records, events, or age estimates to approximate the birthdate. These calculations help organize personal, legal, or historical data accurately, ensuring proper identification, record-keeping, and chronological understanding of a person's life or historical timeline.
