Sunrise – UDP & Sun Times

Know exactly when the day starts and ends. Sunrise, sunset, civil twilight and the Dutch UDP in local time or UTC, now also on Apple Watch.

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 • Civil twilight: BMCT and EECT (sun 6° below the horizon), the EASA / SERA day/night boundary • In the Netherlands: UDP start and end (uniform daylight period, 15 minutes before sunrise to 15 minutes after sunset, as in AIP GEN 2.7) • 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 • An optional reminder before UDP ends, also on your Apple Watch

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.

APPLE WATCH The next event, today's sun times and the pilot times on your wrist, plus a UDP complication for your watch face.
