List of British monarchs by longevity
To maintain consistency within the table, the dates of birth and death for each monarch are given in New Style.
Two measures of the longevity are given—this is to allow for the differing number of leap days occurring within the life of each monarch. The first column is the number of days between date of birth and date of death, allowing for leap days; the second column breaks this number down into years, and days, with the years being the number of whole years the monarch lived, and then days after his or her last birthday.
