So, when are the seasons? The most physically accurate answer is: That moment—the solstice or equinox—can occur at any hour of any day in March, June, September, or December. The date varies by a day or two because the tropical year (365.2422 days) doesn't align perfectly with our calendar's 365 days, necessitating leap years to recalibrate.
The main reason for the seasons is the Earth's axial tilt, which is approximately 23.5 degrees. As the Earth orbits the Sun, different parts of the planet are tilted towards or away from the Sun, resulting in varying amounts of solar energy reaching the Earth's surface. when are the seasons
A deeper layer of complexity comes from —a slow, 26,000-year wobble of Earth’s rotational axis, like a spinning top. This means the orientation of the tilt changes relative to the stars and relative to the point of perihelion. Over thousands of years, the date of the solstices relative to Earth's orbit shifts. So, when are the seasons
These are defined by the of Earth's orbit. They begin and end at specific "seasonal points": The main reason for the seasons is the
