Example Calculation

Let’s understand how the Sunrise Sunset Calculator works with a real example.

Example:

Latitude: 31.5204
Longitude: 74.3587
Date: 15 June 2026

Result:

Sunrise: 05:12 AM (approx.)
Sunset: 07:18 PM (approx.)

Interpretation:

On this date, the day is long due to summer season, resulting in early sunrise and late sunset. This helps users understand seasonal daylight variations.

How the Sunrise Sunset Calculation Works (Simple Explanation)

Without going into technical complexity, the tool works based on Earth’s rotation and tilt.

Earth rotates once every 24 hours
The tilt of Earth changes sunlight angle throughout the year
Latitude affects how much sunlight a location receives
Longitude helps adjust local time differences

By combining these factors, the calculator estimates when the sun will appear and disappear from the horizon.

Sunrise vs Sunset – Understanding the Difference

Sunrise: The moment the sun appears on the horizon in the morning
Sunset: The moment the sun disappears below the horizon in the evening

These times change daily due to Earth’s tilt and orbit around the sun.

Seasonal Impact on Sunrise and Sunset

Sunrise and sunset times vary throughout the year:

Summer: Early sunrise, late sunset (long days)
Winter: Late sunrise, early sunset (short days)
Equinox: Nearly equal day and night

This tool helps you track these seasonal changes accurately.
