What is the spring equinox and why has it mattered to humans for thousands of years?

In this episode of Modern Bodies, we explore the science, history, and meaning behind the spring equinox 

Why does the equinox happen?

How did early humans track time long before calendars or clocks existed. 

What does the equinox represent and why these seasonal turning points still matter, even in a modern world where we no longer rely on them for survival.

From ancient sites like Stonehenge and Chichén Itzá to early monumental structures like Göbekli Tepe, humans have been observing and marking seasonal changes for over 10,000 years. This episode is an invitation to step outside, look up, and reconnect with the rhythms that have shaped human life for millennia.
