# Henge days for a building

This page computes its dates in the browser when it is opened, and keeps a summary for 60 days afterwards so that links to it can show them. Nobody has opened this one recently, so there is nothing stored to tell yet. Open https://hengedays.com/at/33.77392,-84.32773?q=Fernbank+Museum+of+Natural+History%2C+767+Clifton+Road%2C+Atlanta%2C+GA in a browser, then ask again.

Every date and time is computed from a building outline in OpenStreetMap and the position of the sun, never checked on the ground. Hills, trees and other buildings can block a low sun. Treat each date as a plan to confirm. See https://hengedays.com/terms.md.
