The continent that would never have the sun directly overhead at any time during the year is Antarctica.

Here's why:

* Earth's Tilt: The Earth is tilted on its axis at approximately 23.5 degrees. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year.

* The Tropics: The area between the Tropic of Cancer (23.5 degrees North) and the Tropic of Capricorn (23.5 degrees South) is where the sun can be directly overhead at some point during the year.

* Antarctica's Location: Antarctica is located entirely south of the Antarctic Circle (66.5 degrees South latitude). Because of this, the sun never reaches a point directly overhead.

Instead, during the summer in the Southern Hemisphere, the sun circles around the horizon for 24 hours, resulting in a phenomenon known as "midnight sun." During the Southern Hemisphere winter, Antarctica experiences 24 hours of darkness.
