The Science Behind Summer
Seasons are driven by the tilt of Earth's axis — roughly 23.5 degrees — not by how close the planet is to the Sun. As Earth orbits, each hemisphere leans toward or away from the Sun, changing the angle of sunlight and the length of the day. The astronomical start of a season is pinned to a solstice or an equinox, the precise moment that geometry reaches a turning point.
That is why the start of Summer 2028 lands on a specific date and even a specific time, rather than the first of a month. Equinoxes bring near-equal day and night worldwide; solstices mark the longest or shortest day of the year. Knowing the exact changeover is useful for gardeners, photographers, and anyone tracking daylight hours.
