Sun & Moon Almanac
A full sky almanac for any coordinates and date: sunrise and sunset with compass bearings, civil, nautical and astronomical twilight, golden hour for photography, solar noon with maximum altitude, plus moonrise, moonset, the current moon phase, illumination percentage, age and distance — all drawn on an altitude chart of the whole day.

Notes
- Positions come from compact Meeus-style ephemeris formulas, good to a couple of arc-minutes; rise and set times are typically within a minute or two.
- Golden hour is shown as the span where the sun sits between −4° and +6° above the horizon — the soft, warm light photographers chase.
- The moon rises on average about 50 minutes later each day; roughly once a month a calendar day has no moonrise at all — the tool reports those days explicitly.
- Everything runs locally in your browser; nothing you enter is sent to any server.
