Twice a year, the Earth reaches a point where day and night are nearly equal.
This year the first point falls today, Friday March 20th at 14.46 GMT. This is the equinox, the moment when the Sun crosses the celestial equator (Earth’s equator continued as an imaginary line into the sky).
At this precise instant, light and dark almost stand in balance, marking a natural threshold and the beginning of spring in the Northern Hemisphere.
For thousands of years, humans noticed this moment and built monuments to honour this event:
In Egypt, the Temple of Amun-Ra at Karnak was designed so sunlight would pe*****te deep into hidden inner chambers at key times of the year, illuminating spaces normally shrouded in darkness.
In Mexico, the pyramid of El Castillo at Chichen Itza casts shadows at Equinox sunset down its staircase meeting carved snake heads at the bottom steps, forming the illusion of a serpent descending. This is an incredibly precise convergence of astronomy, geometry and ritual.
In Ireland, 5000 year old passage tombs at Knowth and Loughcrew align with the rising and setting Equinox sun, reflecting a sophisticated awareness of solar cycles and the rhythms of nature.
Callanish Stones on the Isle of Lewis in Scotland track lunar standstills, reminding us that not all cycles are immediate, some unfold over decades, demanding careful observation and patience.
These sites weren’t mere calendars, they were instruments of awareness, blending precise observation with ritual and reflection.
Across continents, humans recognised the same cosmic patterns and marked them in stone, in order to stand the test of time.
The equinox is a reminder that cycles surround us: light grows, darkness recedes and subtle transitions shape both nature and life. By observing these moments, ancient peoples lived in tune with the sky and we can still recognise this today, whether by watching or simply pausing to acknowledge the balance of the moment.
The celestial equator, the Sun, the stones, the shadows, they all point to one thing: we are part of a greater rhythm, and today is a moment to notice, reflect, and honour the cycles that connect Earth, sky and ourselves.
