What Is the Sunrise and Sunset Time Calculator?
The Sunrise and Sunset Time Calculator is a tool designed to help users calculate the sunrise and sunset times for a specific date and geographic location. By entering the date, longitude, and latitude, you can quickly obtain accurate results. Whether you're planning a trip, organizing outdoor activities, or simply interested in astronomical events, this tool provides precise sunrise and sunset times.
What Are Sunrise and Sunset?
- Sunrise: Sunrise refers to the moment when the upper edge of the sun first appears above the horizon. It marks the beginning of daylight. In astronomical terms, sunrise is the time when the center of the sun begins to rise above the horizon.
- Sunset: Sunset is the moment when the upper edge of the sun completely disappears below the horizon, marking the end of daylight and the start of nighttime. Astronomically, sunset occurs when the center of the sun is fully below the horizon.
It's important to note that atmospheric refraction affects the precise timing of sunrise and sunset. Due to refraction, sunlight bends, causing the sun to appear slightly above the horizon during sunrise and delaying its disappearance during sunset.
