Sun Calculator

The Sun Calculator is a handy tool designed to help you determine the exact times of sunrise, solar noon, sunset, and the duration of daylight for any location and date. Whether you’re planning a hike, photography session, or just want to know how much daylight you’ll have, this calculator will give you precise information based on your latitude, longitude, and timezone.

How Does the Sun Calculator Work?

The Sun Calculator uses your location’s latitude, longitude, date, and timezone offset to compute the solar data, providing you with:

  • Sunrise time: When the sun will first appear above the horizon.
  • Solar noon: The time when the sun is at its highest point in the sky.
  • Sunset time: When the sun will dip below the horizon.
  • Daylight duration: The total length of time from sunrise to sunset.

By inputting these values, the Sun Calculator will calculate and display the solar information for your chosen date and location.

Step-by-Step Guide to Using the Sun Calculator

1. Enter Latitude

The first input required is latitude, which tells the calculator where you are on the Earth’s surface from north to south.

  • The latitude range is from -90 (South Pole) to +90 (North Pole).

Example: If you’re in New York, enter 40.7128 (Latitude of New York City).

2. Enter Longitude

The next input is longitude, which specifies the position from east to west on the Earth.

  • The longitude range is from -180 to +180.

Example: For New York, the longitude is -74.0060.

3. Select Date

Choose a specific date to find the solar times. The calculator will give results based on that exact day.

Example: Select April 30, 2026, for your desired solar times.

4. Choose Timezone Offset

The timezone offset indicates your time zone relative to UTC (Coordinated Universal Time).

  • Select the correct UTC offset for your location. For instance, New York uses UTC-5 (Eastern Standard Time) or UTC-4 during daylight saving time.

Example: Select UTC-5 if you’re in New York during standard time.

5. Click “Calculate”

After filling out the form, click Calculate. The tool will process the data and calculate the following:

  • Sunrise time
  • Solar noon time
  • Sunset time
  • Daylight duration

6. Review Results

Once calculated, you’ll see the following details:

  • Sunrise: The time the sun rises.
  • Solar Noon: The time when the sun reaches its highest point.
  • Sunset: The time the sun sets.
  • Daylight Duration: The total hours and minutes of sunlight.

Example Calculation:

For New York (latitude 40.7128, longitude -74.0060) on April 30, 2026, with UTC-5:

  • Sunrise: 6:00 AM
  • Solar Noon: 12:00 PM
  • Sunset: 7:45 PM
  • Daylight Duration: 13 hours, 45 minutes

  5. Simple and Easy to Use:
    The tool is user-friendly and requires only basic geographic and temporal data (latitude, longitude, date, and timezone offset).

FAQs

  1. What is Solar Noon?
    Solar noon is the time when the sun reaches its highest point in the sky. It’s not necessarily at 12:00 PM but depends on your location and time zone.
  2. Why do sunrise and sunset times change daily?
    The Earth’s tilt and orbit around the sun cause the times of sunrise and sunset to shift slightly each day. This variation is more noticeable near the equinoxes.
  3. What if I’m at the poles?
    Near the poles, the sun does not set or rise for extended periods during certain seasons, which is why the calculator will display “No sunrise” or “No sunset” during those times.
  4. Can I use this for different locations?
    Yes, the Sun Calculator works anywhere on Earth as long as you provide accurate latitude, longitude, and timezone information.
  5. How does the calculator handle daylight saving time?
    The calculator adjusts for daylight saving time based on the timezone offset you select. For example, if your region is on daylight saving time, select the correct UTC offset (usually UTC-4 for regions like New York in daylight saving time).

With the Sun Calculator, you can easily determine solar events for any location on Earth. This is particularly helpful for activities like outdoor planning, photography, or simply understanding how much daylight you can expect on a specific day.
