Good to know

From the east end of the Mall, under Admiralty Arch. On ceremony days the Mall is closed.

London has no regular grid: this alignment is computed from the real geometry of the street. The Mall’s trees and haze over the Thames can hide the sun even on the right days.

Dates for 2026–2030, worked out by Duskbox’s own astronomy engine: the sun from NREL’s SPA, the moon topocentric, both with atmospheric refraction.
