1. What is Daylight Calculation?

Daylight calculation determines the duration between sunrise and sunset at a specific location. This measurement is important for various applications including agriculture, solar energy planning, and outdoor activity scheduling.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Sunrise Time — Local time when the sun appears above the horizon
• Sunset Time — Local time when the sun disappears below the horizon

Explanation: The calculator computes the difference between the two times to determine total daylight duration.

3. Importance of Daylight Calculation

Details: Knowing daylight hours helps farmers plan work schedules, assists architects in daylighting design, informs solar energy production estimates, and helps travelers plan outdoor activities.

4. Using the Calculator

Tips: Enter sunrise and sunset times in 24-hour format. Times should be from the same date and location for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why does daylight duration change throughout the year?
A: Daylight varies due to Earth's axial tilt and orbit around the sun, causing seasons with different day lengths.

Q2: What's the difference between civil twilight and daylight?
A: Daylight is when the sun is above the horizon. Civil twilight occurs slightly before sunrise and after sunset when there's still enough light for most outdoor activities.

Q3: How does latitude affect daylight hours?
A: Near the equator, day length remains relatively constant year-round. At higher latitudes, daylight varies dramatically between summer and winter.

Q4: Does daylight saving time affect these calculations?
A: No, the actual daylight duration is unaffected by clock changes, but local time representations will differ.

Q5: Where can I find accurate sunrise/sunset times for my location?
A: Many weather services and astronomy websites provide location-specific sunrise/sunset times based on latitude and longitude.
