How to work out 54 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 54th birthday. Leap years come every four years, except century years not divisible by 400, so a 54-year span covers 13 or 14 of them.
+ 13 or 14 leap days
= 19,723 or 19,724 days
