How to work out 43 years in days
Multiply the years by 365, then add one day for every February 29 between the birth date and the 43rd birthday. Leap years come every four years, except century years not divisible by 400, so a 43-year span covers 10 or 11 of them.
43 years in days
43 × 365 = 15,695 days
+ 10 or 11 leap days
= 15,705 or 15,706 days
+ 10 or 11 leap days
= 15,705 or 15,706 days
