Daylight

Know exactly when the sun rises, when the light turns golden, and when it's safe to breathe deep — all in one place.

Daylight gives you a complete picture of the sky and air for any location on Earth: precise solar and lunar timing, a full year of daylight at a glance, and real-time air quality, all built around a single, fast, no-clutter interface.

☀️ Complete Solar Timing
Get every event that matters for your day, not just sunrise and sunset:

Sunrise & sunset
Dawn & dusk (civil twilight)
First light & last light (astronomical twilight)
Solar noon
Golden hour
Current solar angle (elevation), updated in real time for your location
Total daylight duration
Local time zone for your chosen location

🌙 Moon Phases & Moonlight
Track the moon right alongside the sun — moonrise & moonset, current phase, and illumination percentage, so you always know how much moonlight you'll have for a night hike, a late drive home, or a bit of stargazing.

📅 A Full Year of Daylight, Visualized
See how daylight shifts across the entire year in one interactive bar chart — pick a starting date, then tap anywhere on the chart to instantly compare two days side by side. Sunrise, sunset, daylight length, UV index, and every twilight phase are laid out with the exact difference between your two dates, so you can see at a glance how much earlier the sun will rise next month, or how many extra minutes of daylight you'll gain by the solstice.

Works correctly everywhere on the planet — including the Arctic and Antarctic Circles, where the sun can stay up (or stay down) for weeks at a time.

🔆 UV Index
See an estimated peak UV index for any day based on solar elevation and altitude, so you know how much sun protection you'll need before you head out.

🌍 Air Quality (AQI)
A 24-hour, hour-by-hour air quality chart for your location, color-coded to the EPA's Good–Hazardous scale, plus a live current reading pulled from the nearest monitoring station. Check today, or look ahead a few days before you plan an outdoor workout, a hike, or a day with the kids outside.

📍 Any Location, Instantly
Search any city or drop a pin — Daylight pulls up sun, moon, UV, and air quality for wherever you need it, whether that's home, your next trip, or somewhere you're just curious about.

Why people use Daylight:

📷 Photographers — never miss golden hour or blue hour again
🥾 Hikers & outdoor athletes — plan around daylight, moonlight, and air quality
✈️ Travelers — check sunrise/sunset and time zone before you land
🌤️ Anyone sensitive to UV or air quality — know before you go
🌱 Gardeners & early risers — track how daylight shifts through the seasons
🌙 Stargazers & night owls — know exactly how much moonlight to expect
🎣 Anglers & hunters — plan around moon phase, solar timing, and legal shooting light

A note on the data: Solar and lunar positions, angles, and timing are all calculated astronomically on your device — the math happens right in the app, so almost no data ever needs to be pulled from the network to show you sun and moon info. UV index is a clear-sky estimate based on sun position and elevation, and doesn't account for cloud cover. Air quality forecasts come from modeled atmospheric data, supplemented with a live reading from the nearest monitoring station when available — actual conditions can vary.

Simple, fast, and built for anyone who wants to know what the sky is doing today — and every day this year.
