What Time is it Going to Get Dark Today?

The question of when it’s going to get dark is a common one, especially during the summer months when people want to spend time outdoors. Whether you’re planning a picnic or a barbecue, knowing when the sun will set can help you plan your activities accordingly. In this article, we’ll explore some of the factors that influence when it gets dark and how you can determine what time to expect sunset in your area.

Factors that Affect When it Gets Dark

There are several factors that influence when it gets dark, including:

  • Time of year
  • Latitude
  • Longitude
  • Altitude
  • Weather conditions

Time of Year

The time of year is one of the most significant factors that influence when it gets dark. During the summer months, there are more daylight hours than during the winter months. This is due to the tilt of the earth’s axis, which causes some areas of the planet to receive more direct sunlight than others. The closer you are to the equator, the less variation you’ll see in the length of daylight throughout the year.

Latitude and Longitude

Latitude and longitude also play a role in when it gets dark. Areas closer to the equator experience roughly the same amount of daylight throughout the year, while areas closer to the poles experience significant variation in the length of daylight. For example, in parts of Alaska, the sun doesn’t set at all during the summer months, while in the winter, there may be only a few hours of daylight.


Altitude can also affect when it gets dark. At higher altitudes, the atmosphere is less dense, which means that the sun’s rays have to travel farther to reach the ground. This can result in the sun appearing to set later than it does at lower elevations.

Weather Conditions

Finally, weather conditions can also influence when it gets dark. Cloud cover can cause the sky to darken earlier than it would on a clear day, while haze or pollution in the air can make it appear as though the sun has set before it actually has.

How to Determine When it Gets Dark in Your Area

Now that we’ve explored some of the factors that influence when it gets dark, let’s look at how you can determine what time to expect sunset in your area.

Consult a Sunrise/Sunset Calculator

One of the easiest ways to determine when it gets dark in your area is to consult a sunrise/sunset calculator. These tools take into account your location and the time of year to provide an accurate estimate of when the sun will rise and set each day. Most weather websites and apps have this feature built-in, or you can use an online calculator.

Check Your Local Weather Forecast

Another option is to check your local weather forecast. Many forecasts include information about the expected sunrise and sunset times for your area, which can help you plan your activities accordingly.

Use a Sun Calculator

If you want to get more in-depth information about the movement of the sun throughout the day, you can use a sun calculator. These tools allow you to input your location and the time of year to see how the sun’s position will change throughout the day. You can also see when the sun will be at its highest point in the sky, which can help you plan activities that require direct sunlight.


Knowing when it’s going to get dark can help you plan your day and make the most of your time outdoors. By taking into account factors like time of year, latitude and longitude, altitude, and weather conditions, you can get a better idea of when to expect sunset in your area. By using the tools and resources we’ve outlined in this article, you can always stay on top of the changing seasons and enjoy your outdoor activities to the fullest.
