This is a list of Presidents of India by age. This table can be sorted to display the Presidents by name, order of office, date of birth, age at inauguration, length of retirement, or lifespan. Two measures of longevity are given; this is to allow for the differing number of leap days occurring within the life of each President. The first figure is the number of days between date of birth and date of death, allowing for leap days; in parentheses the same period given in yearsand days, with the years being the number of whole years the President lived, and the days being the remaining number of days after his last birthday. Where the president in question is still living, the longevity is calculated up to 9 February 2017.
