The summer solstice will occur on Thursday, June 20, 2024, at 4:51 PM. You may have some questions. Well, I have the answers for you. What is the summer solstice? The summer solstice marks the point when the Earth is tilted toward the sun at its maximum angle. As a result, the sun appears at its highest elevation in the sky. This elevation changes very little for several days before and after the summer solstice, as these changes occur in very small increments. Source: NASA T
