The yearly seasons are more than just a change in the calendar; they are a fundamental driver of the planet's ecological and biological systems. Whether it's the timing of a medical treatment or the migration of a protected species, the "when" of our world is almost always dictated by the season.

Research suggests that seasonal changes in sunlight and UV radiation can affect our immune systems. For example, studies in Northern Israel found that children's antibody levels following certain vaccinations were higher when administered in winter compared to summer. The yearly seasons are more than just a
Every year, mid- and high-latitude regions experience a predictable sequence of temperature shifts, daylight length changes, and biological transformations. While many cultures associate seasons with calendar dates, the underlying cause is not Earth’s distance from the Sun but the (approximately 23.5°) relative to the plane of its orbit (the ecliptic). This paper explains how axial tilt creates seasons, why seasonal contrasts vary by latitude, and how seasonal changes propagate through natural and human systems. Research suggests that seasonal changes in sunlight and
