Figures are for calendar 2027 unless a heading says otherwise, worked out with NOAA's solar equations and the IANA time zone database (version 2026e) at each place's coordinates from GeoNames. Sunrise and sunset put the sun's center 0.833° below a flat horizon, so hills move a real place by minutes. Download the figures.
