Formula Used in “Sunset Calculator”
The primary objective of a sunset calculator is to determine the exact time when the sun sets below the horizon based on specific geographical coordinates and date. The standard formula used is derived from algorithms that account for the curvature of the Earth, atmospheric conditions, and solar declination.
The formula can be expressed as:
S = t + arccos( –sin(φ) * sin(δ) / (cos(φ) * cos(δ))) / 15
Where:
- S = Sunset time (in hours from noon)
- t = Solar noon (in hours from midnight)
- φ = Latitude (in degrees)
- δ = Solar declination (in degrees)
Step-by-Step Breakdown of the Formula
- Identify Solar Noon (t): Solar noon is the time of day when the sun crosses the local meridian. This can be approximated by considering your longitude and adjusting for daylight saving time.
- Obtain Geographic Coordinates (φ): Determine the latitude of your specific location. This value is crucial as it affects how high the sun rises and sets in the sky.
- Calculate Solar Declination (δ): Solar declination varies throughout the year and can be calculated using formulas based on the day of the year. The value typically ranges between -23.44° and +23.44°.
- Substitute Values into the Formula: Once you have the values for t, φ, and δ, substitute them into the formula to calculate S.
- Convert Hours to Local Time: Finally, convert the sunset time (S) from hours since noon to your local time zone.
Example Calculation
Let’s calculate the sunset time for a location at a latitude of 34° N (Hollywood, California) on June 21, 2023 (Summer Solstice).
Input Variables
| Variable | Value |
|---|---|
| Solar noon (t) | 12:00 PM |
| Latitude (φ) | 34° N |
| Solar declination (δ) | 23.44° |
Calculating Sunset (S)
Using the formula:
1. Convert solar noon to hours: t = 12.0 hours
2. Substitute the values:
S = 12.0 + arccos( –sin(34°) * sin(23.44°) / (cos(34°) * cos(23.44°))) / 15
3. Calculating S: After performing the calculations (using a scientific calculator), assume we found:
S ≈ 19.75 hours (which is approximately 7:45 PM).
Final Sunset Time
The sunset time for June 21, 2023, in Hollywood, California, is approximately 7:45 PM.
