1. What is Daylight Calculation?

Daylight calculation determines the duration between sunrise and sunset, providing the total hours of daylight for a given day. This measurement is important for various applications including agriculture, astronomy, and daily planning.

2. How Does the Calculator Work?

The calculator uses a simple time difference formula:

Where:

• \( \text{Sunrise} \) — Time when the sun appears above the horizon (24-hour format)
• \( \text{Sunset} \) — Time when the sun disappears below the horizon (24-hour format)

Explanation: The calculator computes the exact time difference between the two input times and converts it to decimal hours.

3. Importance of Daylight Calculation

Details: Knowing daylight hours helps in planning outdoor activities, agricultural operations, energy management, and understanding seasonal changes. It's also crucial for photographers and astronomers.

4. Using the Calculator

Tips: Enter sunrise and sunset times in 24-hour format (HH:MM). Ensure sunset time is later than sunrise time for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What time format should I use?
A: Use 24-hour format (e.g., 06:30 for 6:30 AM, 18:45 for 6:45 PM).

Q2: Can I calculate daylight across midnight?
A: No, this calculator assumes sunset occurs on the same calendar day as sunrise.

Q3: How precise is the calculation?
A: Results are precise to two decimal places (about 1 minute resolution).

Q4: Does this account for daylight saving time?
A: The calculator works with whatever times you input. Ensure consistency in your time references.

Q5: Why is daylight duration important?
A: Daylight affects human circadian rhythms, plant growth cycles, solar energy production, and many ecological processes.
