Why do we separate spring from the other seasons? Because spring serves a unique, non-negotiable role in the survival of the planet.
Many global holidays, festivals, and cultural traditions are tethered to the definition of spring. For example, Easter and Passover are intrinsically linked to the timing of the vernal equinox. Persian New Year, or Nowruz, marks the exact day of the equinox as a celebration of new beginnings. Holi, the Hindu festival of colors, celebrates the arrival of spring and the triumph of good over evil, while May Day traditionally honors the fertility of the Earth as the season reaches its peak. Environmental Dynamics and Climate Shifts
In the modern era, the definition of spring is facing a major disruption due to global climate change. Scientists observe that "false springs" are becoming more common, and the biological markers of spring are arriving earlier than they did decades ago.
