The equinoxes, about March 21 and September 21, mark the two days a year when the sun appears over the equator. Check this site for a lot more information.

Even in the summer in the Arctic, the tilt of the earth is such that the sun only appears above the Tropic of Cancer -- a long way from the Arctic.
