The Sun passes directly overhead (i.e., through the zenith) at some point during the year in locations within the tropics, which are the latitudes approximately between +/- 23.5° of the equator. This phenomenon is due to the Earth's tilt and rotation, which causes the Sun's position in the sky to change throughout the year. At other latitudes outside of the tropics, the Sun's path across the sky is lower and more angled, so it never passes through the zenith.
