How to work out 59 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 59th birthday. Leap years come every four years, except century years not divisible by 400, so a 59-year span covers 14 or 15 of them.
59 years in days
59 × 365 = 21,535 days
+ 14 or 15 leap days
= 21,549 or 21,550 days
+ 14 or 15 leap days
= 21,549 or 21,550 days
