Understanding Twilight Times: A Quick Guide

Twilight—the period between sunset and night or between night and sunrise—is divided into three phases: civil, nautical, and astronomical. Each phase has distinct characteristics and durations, influenced by your geographical location and the time of year.

What Are the Phases of Twilight?

• Civil Twilight: Occurs when the sun is just below the horizon, providing enough light for most outdoor activities without artificial lighting.

• Nautical Twilight: Happens when the sun is between 6 and 12 degrees below the horizon, allowing sailors to take reliable star sightings for navigation.

• Astronomical Twilight: Takes place when the sun is between 12 and 18 degrees below the horizon, offering dark skies suitable for astronomical observations.

How Do Twilight Times Vary Across the United States?

Twilight times differ based on your location and the date. For example:

• Los Angeles, CA: On June 17, 2026, civil twilight ends at 8:56 PM, nautical twilight ends at 9:36 PM, and astronomical twilight ends at 10:22 PM. (timeanddate.com)
