How to work out 71 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 71st birthday. Leap years come every four years, except century years not divisible by 400, so a 71-year span covers 17 or 18 of them.
71 years in days
71 × 365 = 25,915 days
+ 17 or 18 leap days
= 25,932 or 25,933 days
+ 17 or 18 leap days
= 25,932 or 25,933 days
