Atmospheric Twilight Schedule in Delhi

Sun angles relative to horizon: Civil (0° to 6°), Nautical (6° to 12°), Astronomical (12° to 18°).

Civil Twilight
Dawn: 05:42Dusk: 18:52

Sufficient natural light for outdoor activities without artificial lighting.

Nautical Twilight
Dawn: 05:14Dusk: 19:20

Horizon visible at sea; bright navigational stars can be sighted.

Astronomical Twilight
Dawn: 04:46Dusk: 19:48

Threshold between twilight and complete optical night sky darkness.

Track the Sun's Path for Any City on Earth

Whether you are an outdoor runner trying to beat the dark, a photographer planning a sunset shoot, or a camper who needs to know exactly when to pitch a tent, knowing the exact time the sun goes down is critical. Our live solar calculator provides precise astronomical data for any location in the world. Simply search for your city to instantly see today's exact sunrise and sunset times, the precise moment of solar noon (when the sun reaches its highest point in the sky), and a live countdown showing exactly how much daylight you have left.

Sunset isn't just a single moment; it is a gradual transition divided into three distinct phases of twilight. Immediately after the sun dips below the horizon, you enter Civil Twilight, where the sky is still bright enough to read a book outside. As the sun drops further, you enter Nautical Twilight, where city lights begin to pop and the first stars appear. Finally, Astronomical Twilight takes over, fading the sky into complete darkness. Our tool breaks down the exact start and end times for each of these phases, so you know exactly when the sky will change.

If you travel frequently, you will notice that the length of a day changes drastically depending on how far you are from the equator. While cities like Quito or Nairobi enjoy a steady 12 hours of sunlight year-round, places like London or Seattle experience wild swings—enjoying up to 16 hours of blazing sunlight in the summer, but suffering through barely 8 hours of light in the dead of winter. This calculator tracks those seasonal shifts daily, giving you a perfect breakdown of your local solar schedule.

We use the official NOAA Solar Position Algorithm. By taking your exact latitude and longitude, along with the specific day of the year, the algorithm calculates the sun's position. It even factors in the tilt of the Earth and the way our atmosphere bends light to give you flawless accuracy.
