Sunrise-Sunset Calculator
Sunrise and sunset times depend on your latitude, longitude and the date, because the Sun follows a different path across the sky through the year. This Sunrise-Sunset Calculator gives you the exact sunrise, sunset and day length for any location and any date.

Usefull information about the Sunrise Sunset Calculator
How does the Sunrise – Sunset Calculator work?
Sunrise and sunset are determined by precise geographical coordinates (latitude and longitude) and date. The calculator uses the US Navy Observatory’s algorithm to determine the exact time of sunrise and sunset at the given geographical location.
My place of residence is not on the list, what should I do?
Don’t worry, you still have two options. You can select My location in the Location dropdown to fetch your geolocation. If it’s not supported by your browser, you can still choose the option called ‘Other Location’ in The Sunrise – Sunset calculator and enter the exact latitude and longitude coordinates of the location.
Why are the location and the date are important when calculating sunrise and sunset time?
The place is because the earth is spherical, so the sun reaches / leaves at different times in different places. The date takes into account because of the angle at which the sun hits the earth, which is also important in determining the exact time of sunrise and sunset.
Why is the sunset so beautiful?
The sun initially emits white light, but it is scattered through the air molecules so it changes the final color of the beam the viewer sees. This is because the shorter wavelength components (for example blue and green) scatter more strongly, so these colors are preferentially removed from the beam resulting the warm ‘romantic’ color of the sunset.
Does the sunrise have the same effect?
Yes, but the sunset is more beautiful than the sunrise, because the air is more polluted in the evening, so the effect is stronger.
Frequently asked questions
How are sunrise and sunset times calculated?
They are computed from your latitude and longitude and the position of the Sun on the chosen date, allowing for the tilt of the Earth and atmospheric refraction.
Why do sunrise times change through the year?
Because the axis of the Earth is tilted, day length and the rising point of the Sun shift with the seasons, giving long days in summer and short days in winter.
What is twilight?
Twilight is the period before sunrise and after sunset when the sky is partly lit. Civil, nautical and astronomical twilight mark how far the Sun is below the horizon.
How long is a day at my location?
Day length is the time between sunrise and sunset, which the calculator shows for your chosen date and location, ranging from a few hours to 24 near the poles.
Does the calculator account for my time zone?
Yes. Results are given in the local time for the location you enter, so the sunrise and sunset times match your clock.
