Dusk is usually the twilight that occurs right before the sunsets. However, dusk appears at different times in the world. In this article, we will discuss when dusk occurs in different regions worldwide and other queries related to the topic.

What Time does Dusk occur in the world?

Unfortunately, there is no universal time for dusk to occur. The time for dusk varies significantly in different parts of the world. Dusk is the twilight stage that occurs before the sun sets on the horizon.

Civil Dusk

This stage of dusk occurs when the sun’s disc goes six degrees under the horizon. This stage is the end of the Civil twilight, which starts when the sunsets. At this stage, the sunlight is still being reflected by the atmosphere, and the sky is colored with different shades of red and orange.

This is also a great time for photographers to capture the soft glow of the sunlight and the sky. Once this stage ends, you need artificial lighting to do activities outdoors. The brightest planets, such as Venus and Jupiter, are typically visible in the night sky during Civil Dusk.  Check Out  Antenna Gain – All you need to Know and 5 Best Mobile Ham Radio Antenna Mounts

Nautical Dusk

During this stage, the sun is twelve degrees under the horizon. When this happens, the nautical twilight is at its end. It becomes increasingly difficult to differentiate water, sky, or land at this stage. Sailors use this stage as a reference point when navigating with the help of stars. During this stage, most constellations and stars are visible.

Astronomical Dusk

This is the stage when night officially begins. The sun is approximately eighteen degrees under the horizon, and the last sunray has left the sky. Even before the stage of Astronomical Dusk, during Astronomical Twilight, the sky generally looks dark. However, there is still a bit of sunlight scattered around the sky. This sunlight can hinder the observation of galaxies and stars. Please check these links out: What are Special Event Stations and What Impacts the Range on Two Way Radios?

Dusk at the Poles?

Around the poles, the day and night cycle lasts a full year. In the summer period, the North and South poles experience the Midnight Sun or Polar Day. The sun is present in the sky for several months

during this stage.

The poles experience Polar Night in the winter period when the sun is nowhere to be seen for months. The transitions between Polar Night and Day are marked by lengthy periods of twilight. Once the sun falls below the horizon, it starts sinking every day, culminating in a fortnight of Civil Twilight.

The Civil Twilight is followed by the Nautical and Astronomical Twilight stages that last about 13 to 14 days. In the spring, the opposite takes place; as Polar Night arrives, the sun stays in the atmosphere for several weeks before it rises to the horizon.

Is Dusk Shorter near the Equator?

The length of twilight or dusk depends on the latitude. Tropical and Equatorial regions have shorter dusk periods than higher latitude locations. There is typically no difference between Astronomical Twilight in summer at high latitude locations before sunrise and after sunset.

This occurs when the sun doesn’t go more than eighteen degrees under the horizon at night. High latitude locations may even experience longer periods of Civil or Nautical twilights.  Please go through these links: 5 Best Police Digital Scanners and What is Antenna Theory?

Dusk in the United States?

The country’s Northern position generally influences the time of dusk in the United States in the Hemisphere. Here are a few cities, along with the time dusk occurs:

  • Dallas: 08:01 Pm
  • Indianapolis: 08: 28 Pm
  • Philadelphia: 07:44 Pm
  • New York City: 07:40 Pm
  • Columbus: 08:15 Pm
  • Denver: 07:43 Pm
  • San Jose: 07:47 Pm
  • San Frisco: 07:50 Pm
  • Los Angeles: 07: 28 Pm
  • Seattle: 08:06 Pm
  • Chicago: 07:37 Pm
  • Houston: 07:52 Pm

According to the statistics given above, dusk appears the earliest in Los Angeles and the latest in Indianapolis. Dusk time by month in the United States:

  • January: 05:11 Pm (Average)
  • February: 05:46 Pm (Average)
  • March: 07:16 Pm (Average)
  • April: 07:46 Pm (Average)
  • May: 08:15 Pm (Average)
  • June: 08:36 Pm (Average)
  • July: 08:34 Pm (Average)
  • August: 08:04 Pm (Average)
  • September: 07:18 Pm (Average)
  • October: 06:31 Pm (Average)
  • November: 04:55 Pm (Average)
  • December: 04:48 Pm (Average)

These statistics show that dusk generally occurs early in winters. Whereas in the summer months, it takes a while for dusk to appear, as it generally appears after 7:15 Pm.
