Plan your light. Golden hour, blue hour, the twilights, which way the sun rises and sets, the moon, and when the sky goes truly dark — for any place, any date. Built for photographers, stargazers and anyone who loves a good sky.
Private. Your photos never leave your browser.
The warm, soft, low-contrast light just after sunrise and before sunset (sun roughly −4° to +6°). The most flattering light of the day.
The cool, even glow before sunrise and after sunset (sun −6° to −4°). Beautiful for cityscapes and calm water.
The sky darkening in stages as the sun sinks to −6°, −12°, then −18°. Past −18° it's as dark as it gets.
Where on the horizon the sun rises and sets — it swings north in summer and south in winter, which is why this matters for planning a shot.
All times and angles are computed from astronomical formulae entirely in your browser — no server, no API, nothing about your plans ever leaves this page. Times are shown in the selected place's local time zone.
