List of current heads of government by time in office

The following list of current heads of government is ordered by the date of taking office. (If a person has served the role more than once, then only the most recent period is noted.) In the somewhat rare situation that two people (such as a president and a prime minister) both have functional (rather than just ceremonial) powers, then both are listed. (Ceremonial leaders are not listed.) Persons who have maintained continuous effective leadership under more than one title are listed from when leadership began, and their current titles are noted. (This is done to make this list a quick reference on how long world leaders have been "in charge.") Abbreviation: Y means years in office.
