Features

Is it dark yet? is a real-time sunset and darkness tracker that tells you instantly whether it is dark outside at your exact location. Here's everything you can do with it:

◐

Real-time darkness status

Instantly see whether it is dark, in twilight, or still daylight at your exact GPS location. The threshold for "dark" is the sun being more than 6° below the horizon — the end of civil twilight.

↑

Sunrise and sunset times

Precise sunrise and sunset times calculated from your latitude, longitude, and the current date using standard astronomical solar position algorithms.

⇆

Civil dawn and civil dusk

Know exactly when first light appears in the morning (civil dawn) and when true darkness begins in the evening (civil dusk) — the moments photographers and astronomers care about.

○

Moon phase and illumination

See the current moon phase and illumination percentage, so you know how much moonlight to expect tonight.

▬

Day progress bar

A visual progress bar shows where you are between first light and last light, with a "Now" marker indicating the current time of day.

⌕

City search worldwide

Search for any city in the world to check its darkness status, sunrise, sunset, and twilight times without sharing your location.

About Is it dark yet?

Is it dark yet? gives you an instant, real-time answer based on your exact location. The sky simulation updates every second, reflecting whether the sun is above the horizon, dipping through civil twilight (−6°), or well below it — the threshold astronomers and photographers use to define true darkness.

Alongside the live sky, you'll find precise sunrise and sunset times, civil dawn and dusk, current sun altitude, moon phase and illumination, and a day-progress bar showing where you are between first light and last light. Search any city to compare times side by side, or check darkness status for major cities around the world.

The site considers it "dark" only after the sun's center drops more than 6 degrees below the horizon — the end of civil twilight. Before that, during civil twilight, there is still enough natural light for most outdoor activities. The sky takes on deep blue and orange hues during this transitional period.

Frequently asked questions

What does "is it dark yet" mean?

The site answers whether the sun has set far enough below the horizon that it is genuinely dark outside — specifically, when the sun is more than 6 degrees below the horizon, which marks the end of civil twilight and the beginning of true nighttime darkness.

What is civil twilight?

Civil twilight is the period when the sun is between 0 and 6 degrees below the horizon. During civil twilight, there is still enough natural light for most outdoor activities without artificial illumination. The sky takes on deep blue and orange hues. Civil twilight begins at civil dawn and ends at civil dusk.

What is the difference between sunset and dusk?

Sunset is the moment the upper edge of the sun disappears below the horizon. Dusk, or civil dusk, occurs when the sun's center is 6 degrees below the horizon — several minutes after sunset. Between sunset and dusk, the sky gradually darkens through civil twilight. The site considers it "dark" only after civil dusk has passed.

What is the difference between dawn and sunrise?

Dawn, or civil dawn, is the moment when the sun's center reaches 6 degrees below the horizon on its way up — the first detectable light of day. Sunrise occurs a few minutes later when the upper edge of the sun first appears above the horizon. Between civil dawn and sunrise, the sky brightens through morning civil twilight.

How does the site calculate sunrise and sunset times?

The site uses the SunCalc JavaScript library, which implements standard astronomical algorithms for solar position. Calculations are based on your exact latitude, longitude, and the current date and time, producing precise sunrise, sunset, civil dawn, and civil dusk values for your location.

What is sun altitude?

Sun altitude is the angular height of the sun above or below the horizon, measured in degrees. A positive altitude means the sun is above the horizon (daytime). Zero degrees means the sun is exactly at the horizon (sunrise or sunset). A negative altitude means the sun is below the horizon — between 0 and -6 degrees is civil twilight, and below -6 degrees is considered dark.

What is the day progress bar?

The day progress bar shows your position between sunrise and sunset. It fills from left (sunrise) to right (sunset) as the day advances, with a "Now" marker indicating the current time. This gives a visual sense of how much daylight remains before the sun sets.

Does the site store my location?

No. Your GPS coordinates are used only within your browser to calculate solar position. They are never transmitted to a server, stored in a database, or shared with third parties. You can also search for any city instead of sharing your location.

Is it dark yet?

Is it dark yet? is a free, real-time tool that tells you instantly whether it is genuinely dark outside at your location. Open the page and allow location access, or search for any city worldwide, and the app calculates the sun's current position to answer the question with a simple “Yes,” “Almost,” or “Not yet.” Alongside the answer, you get live sunrise and sunset times, civil dawn and civil dusk times, a real-time sky simulation, a moon phase indicator, and darkness status for 16 major world cities.

How to use it

When you visit the page your browser prompts for location permission. Grant it and the app uses your GPS coordinates to run the solar calculation immediately. If you decline or are on a device without geolocation, you can search for any city by name. The main display shows a large status word — Yes, Almost, or Not yet — with a live countdown to the next event such as sunset or sunrise. Below that, cards display exact sunrise, sunset, civil dawn, and civil dusk times, the sun's current altitude and azimuth, a day-progress bar, and the current moon phase.

Twilight explained: civil, nautical, and astronomical

Twilight is the period of partial light after the sun dips below the horizon but before the sky goes fully dark. Astronomers divide it into three phases based on how far the sun sits beneath the horizon, measured as its “altitude” in degrees.

Civil twilight

Civil twilight lasts from sunset until the sun's center reaches 6 degrees below the horizon, and again from that point until sunrise in the morning. During civil twilight there is still enough natural light for most outdoor activities without artificial lighting. The sky takes on deep blue and orange tones, and streetlights begin to switch on. The app considers it “almost dark” during this phase and “dark” only after civil twilight ends.

Nautical twilight

Nautical twilight runs from 6 to 12 degrees below the horizon. The horizon is still visible at sea level, which historically allowed sailors to take star sights for navigation, hence the name. To the casual observer the sky appears quite dark, though a faint glow remains near the western horizon after sunset.

Astronomical twilight

Astronomical twilight spans 12 to 18 degrees below the horizon. The sky is dark enough for most purposes, but a very faint residual glow can still interfere with deep-sky astrophotography. Once the sun passes 18 degrees below the horizon, astronomical twilight ends and the sky reaches maximum darkness — the condition the app labels as fully dark.

Why sunset and “dark” are not the same moment

Sunset is the instant the upper edge of the sun disappears below the horizon. At that moment the sun's center is only about 0.3 degrees below the horizon, and the sky is still bright with civil twilight. It takes several more minutes — longer at higher latitudes — for the sun to sink to 6 degrees and end civil twilight. Only then is it genuinely dark by the standard the app uses. So “the sun has set” and “it is dark” describe two different points in time, and the gap between them varies by latitude, season, and your position within your time zone.

How the sunrise and sunset calculation works

The app computes solar position using well-established astronomical algorithms that model the Earth's orbit, axial tilt, and rotation. The inputs are your latitude, your longitude, and the current date and time. From these the algorithm derives the sun's altitude (its angle above or below the horizon) and azimuth (its compass direction) at any given instant. Sunrise is the moment altitude crosses zero going upward; sunset is the same crossing going downward. Civil dawn and civil dusk correspond to the altitude crossing 6 degrees below the horizon. Because the calculation is based on exact coordinates rather than a time-zone average, the results are precise to the minute for your specific location.

Moon phase information

The app displays the current moon phase alongside its illumination percentage — the fraction of the moon's visible face lit by the sun. Phases progress from new moon through waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent before returning to new. The calculation uses the same solar-position library to determine the angular separation between the sun and moon as seen from Earth, which determines how much of the lunar surface appears illuminated to you right now.

Golden hour and blue hour times

Want to know exactly when the light turns golden for photography? The companion Golden Hour Tracker page shows precise golden hour and blue hour start and end times for your location, along with how long each window lasts. Golden hour is when the sun sits between −4° and +6° of elevation — the warm, soft light photographers prize. Blue hour is the deep twilight between −6° and −4°, when the sky turns saturated blue with no direct sunlight.
