How to work out 50 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 50th birthday. Leap years come every four years, except century years not divisible by 400, so a 50-year span covers 12 or 13 of them.
50 years in days
50 × 365 = 18,250 days
+ 12 or 13 leap days
= 18,262 or 18,263 days
+ 12 or 13 leap days
= 18,262 or 18,263 days
