    Taylor, you are probably just taking 65-7 and get 58
    , but that would not count day 7,
    So there are 59 days.

    Looks at a simpler case:
    How many days from June 1 to june 5
    obviously there are 5 days, but ...
    when I take 5-1 I get only 4.
    so that is why I had to add 1 to the subtraction answer.
