A live Zulu clock, plus sunrise, sunset and civil twilight for any airport and date — handy for night-currency planning.
Sunrise, sunset & civil twilight
Airport
Pick an airport to compute sun times (shown in UTC).
How this works
Times come from the standard sunrise equation using the airport’s latitude and longitude, and are shown in UTC.
Sunrise/sunset use the official 90.833° zenith; civil twilight uses 96° (sun 6° below the horizon). Night currency and the definition of night vary by jurisdiction — check your own rules.
