How to work out 65 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 65th birthday. Leap years come every four years, except century years not divisible by 400, so a 65-year span covers 16 or 17 of them.
65 years in days
65 × 365 = 23,725 days
+ 16 or 17 leap days
= 23,741 or 23,742 days
+ 16 or 17 leap days
= 23,741 or 23,742 days
