A method for determining the duration between two dates, typically a birthdate and a specified reference date (often the current date), within a spreadsheet application. This process uses built-in functions to subtract the starting date from the ending date and express the result in years, months, or days. An illustration involves subtracting an individual’s date of birth from today’s date to ascertain their current age.
Employing these techniques offers efficiency in managing data involving lifespans. It provides a crucial utility for demographic analysis, human resources management, and actuarial science, where precise determination of temporal differences is required. Historically, these calculations were performed manually, introducing the potential for error and inefficiency; however, spreadsheet software has automated and streamlined the process, enhancing accuracy and saving time.
