How to work out 79 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 79th birthday. Leap years come every four years, except century years not divisible by 400, so a 79-year span covers 19 or 20 of them.
79 years in days
79 × 365 = 28,835 days
+ 19 or 20 leap days
= 28,854 or 28,855 days
+ 19 or 20 leap days
= 28,854 or 28,855 days
