Normally, an individual can be president for two terms, which would be 8 years. But when a president takes office following the incapacitation of the previous president, and if the new president serves less than half of the previous president's term, then the new president can still have two terms of her/his own, bringing the longest possible current tenure to 10 years minus a day. No president has had a time in office that long under these conditions. FDR had a very long tenure in office because during his time there were no limits to the number of terms a president could serve. After his death the limits were changed by way of a Constitutional Amendment.
