How to work out 36 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 36th birthday. Leap years come every four years, except century years not divisible by 400, so a 36-year span covers exactly 9 of them.
36 years in days
36 × 365 = 13,140 days
+ 9 leap days
= 13,149 days
+ 9 leap days
= 13,149 days
