Every Winter Since — PA Réalt tee

This design shows the direction of the midwinter sunrise at Newgrange's latitude (53.7° N) every century from 3200 BC to AD 2026. Over those five thousand years the sunrise point drifts by about 1.27° as Earth's axial tilt slowly changes. 2026 is marked in gold.

Computed design. Sun-centre sunrise direction at 53.7° N, flat horizon, no refraction; mean axial tilt model (Laskar 1986). Illustrative, not a record of observed sunrises or of light in the Newgrange chamber. Data v0.2.
