46 × 365 = 16,790, plus 11 or 12 leap days

How to work out 46 years in days

Multiply the years by 365, then add one day for every February 29 between the birth date and the 46th birthday. Leap years come every four years, except century years not divisible by 400, so a 46-year span covers 11 or 12 of them.
