Excel Solution: Age Calculation Before 1900

A special structure has been created to reduce age calculation errors in birth dates before 1900. Correction steps have been defined in accordance with the limitations arising from Excel's date system. Basic control mechanisms have been added to detect incorrect date entries. It is intended that the results can be used safely in archive and family tree studies.
