This statement is true. On the summer solstice, which occurs around June 21st, areas above the Arctic Circle (66.5 degrees North latitude) experience 24 hours of continuous daylight because the Earth's tilt in relation to the sun is at its maximum angle towards the North Pole. This means that the entire Arctic Circle is within the area of the Earth that is receiving sunlight (the circle of illumination), resulting in the phenomenon known as the "midnight sun."
