Presidents by time in office The length of time given below is based on the difference between dates. Many presidents were elected multiple times, and to terms that were, in several instances, not consecutive; the length of time given for each president measures their cumulative length of incumbency as president (even if they were elected as acting president). The time after adjournment of one Congress but before the convening of the next Congress is also counted. References Presidents Congress Lists of political office-holders in Spain
