How to work out 37 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 37th birthday. Leap years come every four years, except century years not divisible by 400, so a 37-year span covers 9 or 10 of them.
+ 9 or 10 leap days
= 13,514 or 13,515 days
