    Correct.  It takes almost 365.25 days for the earth to make one complete
    revolution around the sun.  The extra 0.25 day would be a bit much to handle
    time wise, so we stop at 365.  Which leaves us a bit more shy of completing
    a full revolution each year after leap year.  The extra day in a leap year
    every 4 years gets us back on track (mostly).  Since the time to orbit the
    sun is not precisely 365.25 days, we have have the exceptions where there is
    no leap year to even things out.
