Sun Position Calculator
Sun Position Results
The Sun Position Calculator is a powerful tool designed for anyone who needs to know the position of the sun at any given time and location. Whether you’re an astronomer, a photographer, or just curious about the sun’s path, this tool allows you to calculate essential sun parameters like the sun’s elevation and azimuth for a specific place and time. This step-by-step guide will explain how the Sun Position Calculator works, how to use it, and highlight its benefits and features.
What Is the Sun Position Calculator?
The Sun Position Calculator helps users determine the angle at which the sun is located in the sky at a given date and time. It takes into account factors like latitude, longitude, date, and time in UTC (Coordinated Universal Time). Using this tool, you can easily calculate two key sun parameters:
- Sun Elevation: The angle of the sun above the horizon.
- Sun Azimuth: The compass direction where the sun is located.
This tool is ideal for activities like photography (for golden hour calculations), solar panel installations, and more.
How to Use the Sun Position Calculator
The Sun Position Calculator is simple to use. Just follow these steps:
Step 1: Enter Your Location
First, you’ll need to input the latitude and longitude of your location.
- Latitude: This is the angular distance north or south of the equator. Example: New York has a latitude of 40.7128°.
- Longitude: This is the angular distance east or west of the prime meridian. Example: New York has a longitude of -74.0060°.
These values will help the calculator determine the sun’s position relative to your exact location.
Step 2: Set the Date
The date field allows you to choose the specific day for which you want to calculate the sun’s position. Simply select a date from the calendar.
Step 3: Set the Time (in UTC)
The time input field allows you to specify the time of day (in UTC). You can enter the time in hours and minutes. For example, 12:00 (noon) will show the sun’s position at midday.
Step 4: Calculate the Sun’s Position
Click the “Calculate” button to begin the sun position calculation. While the results are being calculated, you will see a progress bar that fills up. This gives you an idea of how long the calculation process will take.
Step 5: View the Results
Once the calculation is complete, the results will be displayed. You will see:
- Sun Elevation: The sun’s height above the horizon in degrees.
- Sun Azimuth: The compass direction (0° to 360°) of where the sun is located.
You can easily copy or share these results via the Copy Results or Share Results buttons.
Step 6: Reset the Calculator
If you need to start over, click the “Reset” button to clear all inputs and reset the form to default values.
Practical Example
Let’s consider a practical example: you’re a photographer and want to know the position of the sun in New York City on February 15, 2026, at 12:00 PM UTC.
Steps:
- Enter Latitude: 40.7128 (New York City).
- Enter Longitude: -74.0060 (New York City).
- Choose the Date: February 15, 2026.
- Enter the Time: 12:00 UTC.
After clicking Calculate, the Sun Position Calculator will show you the sun elevation and sun azimuth at that exact time and location.
Result Example:
- Sun Elevation: 55.26°
- Sun Azimuth: 180° (South)
This information helps you determine how high in the sky the sun will be and the direction it will be facing. In this case, the sun is about 55 degrees above the horizon and directly to the south.

FAQ Section
1. What is sun elevation?
Sun elevation refers to the angle of the sun above the horizon. A value of 90° means the sun is directly overhead, while 0° means it is at the horizon.
2. What is sun azimuth?
Sun azimuth is the compass direction where the sun is located at a given time, measured in degrees from the north (0°).
3. Why do I need the Sun Position Calculator?
The calculator helps you determine the sun’s position for any location and time, which is valuable for activities like photography, solar panel installation, and astronomical observation.
4. What units are used for sun elevation and azimuth?
Both are measured in degrees (°). Sun elevation is from 0° (horizon) to 90° (directly overhead), and azimuth ranges from 0° to 360°.
5. Can I use the calculator for any location?
Yes, as long as you know the latitude and longitude of your location, the calculator can provide the sun’s position anywhere on Earth.
6. What is the difference between UTC and local time?
UTC (Coordinated Universal Time) is the time standard used worldwide, while local time is specific to your timezone.
7. How accurate is the sun position calculation?
The tool provides accurate sun position calculations based on latitude, longitude, date, and time.
8. Can I use the calculator for past dates?
Yes, you can input past dates to find out the sun’s position on any given day.
9. Can I use this tool for sunrise or sunset calculations?
While the tool does not directly calculate sunrise or sunset, the sun’s elevation value can help you determine when these events occur.
10. What does the “Reset” button do?
It clears all inputs and resets the form to its default values.
11. Can I share the results with others?
