Sunset Calculator
Using our sunset calculator, you will never miss the best moment of the day ever again.
What Sunset Calculator does
The Omni Calculator sunset calculator determines the exact time the sun will set for any location on Earth. Users input their latitude, longitude, and time zone, then choose between standard sunset or different dusk types—civil, nautical, or astronomical. The result provides a precise local time, helping users plan evening activities or observations. The tool also offers brief explanations of the physics involved, such as atmospheric refraction and the sun's apparent path, making the calculations accessible without requiring prior astronomical knowledge.

Best for
Travelers, photographers, and outdoor enthusiasts who need accurate local sunset times to plan activities or capture lighting conditions.
Limitations
- Results depend on accurate location and time zone input
- No unit switching between metric and imperial measurements
- Atmospheric conditions are not factored into the astronomical calculations
Sunset Calculator FAQ
- Can the calculator account for local obstacles like mountains or buildings?
- The calculator offers four dusk types—Sunset, Civil, Nautical, and Astronomical—each representing how far the sun is below the horizon, with Sunset being the standard point when the upper limb disappears.
- What is the difference between the sunset types offered?
- Sunset marks when the sun's upper limb touches the horizon; Civil dusk is when the sun is 6 degrees below, allowing some natural light; Nautical dusk is at 12 degrees, when the horizon is still visible; Astronomical dusk is at 18 degrees, when the sky is completely dark.
- Does the tool consider atmospheric refraction?
- Yes, the underlying physics computations include a refraction correction to provide accurate time stamps for when the sun dips below the horizon line at the specified location.
