Sunrise Sunset & Day Length

Know exactly when the sun rises, when it sets, and when the light turns gold — anywhere in the world. Daylight gives you precise sunrise, sunset and day-length times, plus the golden hour and blue hour windows that photographers plan their day around.

Most sun apps stop at a rise and set time. Daylight goes further: it maps the full arc of the day — every twilight phase, the exact warm and cool light windows morning and evening, the sun's height through the day, and how much your daylight is growing or shrinking. Every number is computed on your device with the NOAA solar-position algorithm. No account, no sign-in, nothing sent to a server.

WHAT YOU GET
- Precise sunrise, sunset and solar noon for your location, updated for the day
- Golden hour and blue hour windows for both morning and evening, so you can be in position before the light arrives
- Civil, nautical and astronomical twilight times for planning the edges of the day
- Day length plus a day-over-day figure showing how many minutes you are gaining or losing
- A timeline of the sun's elevation across the whole day, and a year chart marking the solstices and equinoxes
- Optional reminders that nudge you before sunrise and before golden hour

PERFECT FOR
- Photographers and filmmakers chasing the best natural light
- Hikers, runners and cyclists planning around dawn and dusk
- Anyone tracking the lengthening or shortening days through the seasons
- Travellers who want the sun times for any city they are heading to

WHY NOT JUST SEARCH ONLINE?
A quick search gives you one sunrise and one sunset for today. It won't tell you the golden hour window, the blue hour before it, the twilight phases, how the sun climbs through the day, or how fast your days are changing — and it can't remind you before the light is right. Daylight keeps all of that in one place and works even with no signal.

PRIVACY
All calculations run locally on your device. There is no account and no tracking. Your location is used only to compute sun times and never leaves your phone.
