How to work out 27 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 27th birthday. Leap years come every four years, except century years not divisible by 400, so a 27-year span covers 6 or 7 of them.
+ 6 or 7 leap days
= 9,861 or 9,862 days
