Depends on what you mean by sunrise/sunset. “The relative position of the sun’s edge drops below/rises above the tangent of the average surface at sea level” is pretty easy to calculate many years out; the complications are deviations in Earth’s orbit. “I can/can’t see the sun anymore” depends on local weather, good luck.
