To understand the dates of the seasons, one must first understand their cause. The seasons are not caused by the Earth's distance from the Sun—a common misconception—but rather by the axial tilt of the Earth. Our planet is tilted at an angle of approximately 23.5 degrees relative to its orbital plane. As the Earth orbits the Sun, this tilt causes different parts of the planet to receive varying amounts of solar radiation at different times of the year.
Global warming has led to an expansion of the thermal summer season. Studies indicate that summers are lengthening while winters are shrinking in duration. In many temperate zones, the onset of spring-like temperatures is occurring weeks earlier than the historical average. This creates a dissonance between the calendar and the environment; the astronomical calendar states it is still winter (March 1st), but the flowering trees have already bloomed. four seasons dates
This system aligns more closely with the "felt" experience of the seasons in many mid-latitude regions, where June, July, and August are generally the warmest months, regardless of the exact date of the solstice. To understand the dates of the seasons, one
Before the advent of modern meteorology, the dates of the seasons were inextricably linked to phenology—the study of cyclic and seasonal natural phenomena, especially in relation to climate and plant and animal life. As the Earth orbits the Sun, this tilt
