Estimate sunrise, sunset, solar noon, day length, and twilight times from date, latitude, longitude, and time zone. This calculator is useful for hiking, backpacking, camping, photography, hunting, fishing, and outdoor trip planning.
Date:
Enter the date you want to calculate. Day length changes throughout the year.
Coordinates:
Enter latitude and longitude in decimal degrees. North latitude is positive, south latitude is negative, east longitude is positive, and west longitude is negative.
Time zone:
Enter the standard UTC offset for the location. For example, Central Standard Time is -6 and Eastern Standard Time is -5.
A sunrise sunset calculator helps plan hiking start times, camping schedules, trail turnaround times, photography sessions, fishing trips, hunting windows, and safe daylight travel.
Always leave extra time before dark when hiking or backpacking. Terrain, weather, navigation, and group pace can make travel take longer than expected.
This calculator estimates sun times using solar position math:
Solar noon, hour angle, solar declination, and equation of time are used to estimate sunrise and sunset.
Solar noon is the time when the sun is highest in the sky for that location. It is not always exactly 12:00 PM on the clock.
Civil twilight is the brighter twilight period when the sun is just below the horizon. It is often useful for outdoor visibility before sunrise or after sunset.
Sunrise and sunset depend on date, latitude, longitude, time zone, and Earth’s tilt. Locations farther north or south can have much longer or shorter days depending on season.
This calculator gives a practical estimate. Local horizon height, elevation, mountains, clouds, trees, atmospheric refraction, and calculation assumptions can create small differences.
