Sunrise & Sunset at Airport

Calculate sunrise, sunset, and golden hour times for any airport on any date. Plan your arrival or departure around daylight.

Frequently Asked Questions

What is the difference between civil, nautical, and astronomical twilight?
Civil twilight (sun 0-6 degrees below horizon) provides enough light for outdoor activities without artificial lighting. Nautical twilight (6-12 degrees) allows the horizon to be visible at sea for navigation. Astronomical twilight (12-18 degrees) is when the sky is dark enough for astronomical observations. For planespotting, civil twilight provides the best photography light.
Why are sunset times important for airport operations?
Airport lighting systems switch between day and night configurations based on ambient light conditions. Runway approach lighting, taxiway edge lights, and PAPI/VASI systems activate during twilight. Noise curfews at many airports are also tied to specific evening and morning hours.
When is the best time for planespotting photography?
The golden hour (the first and last hour of sunlight each day) produces warm, directional light that is ideal for aviation photography. Use this tool to find exact golden hour times at your chosen airport. Overcast days provide even, diffuse lighting that can also work well.

Methodology

Sunrise and sunset times are calculated using standard solar position algorithms based on the airport's latitude, longitude, and the selected date. The calculation accounts for atmospheric refraction (approximately 0.833 degrees), which causes the sun to appear above the horizon slightly before it geometrically rises. Civil twilight (sun 6 degrees below horizon), nautical twilight (12 degrees), and astronomical twilight (18 degrees) are also computed. All times are displayed in the airport's local timezone.
