The exact length, in days, of Earth's true sidereal orbital period is 365.256366 (364 and 1/4 ) days or 1.0000175 years.
As this is not a whole number of days, our Earth calender is arranged to have normal years and leap years. We make a normal year have 365 days and a leap year have 366 days. We arrange it so that a leap year happens every 4th year so that extra day makes up for the four 1/4 days we need make the orbit position the same over time.
