Sunrise – UDP & Sun Times

Sunrise, sunset & twilight

Free

Know exactly when the day starts and ends. Sunrise, sunset and UDP (civil twilight) for your position, in local time or UTC. Sunrise shows when the sun rises and sets where you are — and the times that matter for flying. Built for pilots, student pilots and flight school operations, and beautiful enough for everyone. WHAT YOU SEE • Sunrise and sunset for your current location • UDP start and UDP end (BMCT / EECT: civil twilight, sun 6° below the horizon) • Solar noon and total daylight • A countdown to the next event: "Sunset in 1h 12m" • Local time or UTC in aviation style (0542Z) with one tap ANY DATE Scroll the date wheel, tap the arrows or swipe across the sun's path to plan a flight days or months ahead. A SKY THAT FOLLOWS THE SUN The whole screen follows the real position of the sun: deep blue night with stars, pink dawn, bright day, golden evening. The sun — or the moon at night — travels along today's arc. PRIVATE BY DESIGN Everything is calculated on your device with the NOAA solar algorithm. No account, no sign-in, and your location is never shared with us or with advertisers. Works on iPhone and iPad. Free, supported by a single small banner. For planning and information only. Not for operational use: always check official sources such as the AIP.
