How many days are there in 57 years?
it depends on when the leap year will begin. I am going to assume that the leap year will start on the fourth year in your 57 year span.a total of 20,805 days in 57 years without counting the leap year every fourth yeara total of 20,819 days in 57 years if the leap year occurs in the fourth year of your 57 year time span.
