How to work out 63 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 63rd birthday. Leap years come every four years, except century years not divisible by 400, so a 63-year span covers 15 or 16 of them.
+ 15 or 16 leap days
= 23,010 or 23,011 days
