Sunset Calculator
Sunrise & Sunset Calculator
Planning an evening walk, outdoor event, or photography session? Knowing the exact sunset time helps you make the most of daylight. The Sunset Calculator provides accurate sunset times for any city or location worldwide, helping you plan your day or evening activities with precision.
This easy-to-use calculator shows the exact time of sunset, based on your date, location, and time zone — whether you’re checking today’s sunset or planning for a future date.
What Is a Sunset Calculator?
A Sunset Calculator determines the exact local time the sun sets below the horizon for any date and place on Earth.
It factors in:
- Your latitude and longitude
- The date and time zone
- The Earth’s tilt and orbit
With these parameters, the calculator provides accurate results for sunset, sunrise, and even twilight phases.
How the Sunset Calculator Works
The Sunset Calculator uses astronomical equations based on the position of the sun relative to the Earth’s rotation.
Core Formula (Simplified)
The calculation is derived from: cos(ω)=−tan(ϕ)×tan(δ)\cos(\omega) = -\tan(\phi) \times \tan(\delta)cos(ω)=−tan(ϕ)×tan(δ)
Where:
- ω (omega) = hour angle of the sun
- φ (phi) = observer’s latitude
- δ (delta) = solar declination
Once the hour angle is known, the sunset time is calculated by converting it to local time using longitude and time zone data.
Don’t worry — the calculator handles all this complex math for you instantly!

Twilight continues for 20–40 minutes after the sun sets.
🧭 3. Your Longitude Affects Sunset Time:
Cities to the west experience later sunsets within the same time zone.
🌍 4. Near the Poles, the Sun May Not Set at All:
During summer, polar regions experience midnight sun — 24 hours of daylight.
