About these dates
A henge day has the sun on the horizon, under 1.5° up, square to the wall. Golden is under 6°, low sun under 15°. A window of several days has a best day, when the sun is lowest, and that day's time. Every date and time here is computed from the building outline in OpenStreetMap and the position of the sun, never checked on the ground. An outline a degree off moves the head-on minute by about four minutes. Hills, trees and other buildings can block a low sun. Treat each date as a plan to confirm before you travel. See Terms and accuracy.
