If you care only about the sun's gravitational pull on the planet and want to ignore other celestial bodies, you may also use Kepler's laws of planetary motion (http://en.wikipedia.org/wiki/Kepler%27s_laws_of_planetary_motion#Computing_position_as_a_function_of_time) to analytically calculate the planets position at a given time.
