Reference

The sunrise and sunset times are calculated using the SunCalc library, which applies algorithms based on the geometric relationships between the Earth, Sun, and the observer's location. It accounts for factors like latitude, longitude, date, and time zone to determine the precise timings of sunrise and sunset for a given location. The day length is derived by calculating the difference between the sunrise and sunset times, providing the total duration of daylight hours on a specific date and location.

Calculation

The day length calculation involves:
1. Obtaining the sunrise and sunset times from the SunCalc library for the user's location.
2. Calculating the time difference in milliseconds between the sunset and sunrise times.
3. Converting the time difference from milliseconds to seconds.
4. Formatting the total seconds into hours, minutes, and remaining seconds for a more readable representation.
The formatted day length is displayed to the user, showing the total duration of daylight hours in an easily understandable format.
