Why do sunrise times depend on location?

Sunrise and sunset are determined by latitude, longitude, date, time zone and the Sun's apparent position.

Solar noon is the time when the Sun is highest in the sky for the selected location.

Does this handle polar day or polar night?

Yes. When the Sun does not cross the ordinary sunrise or sunset threshold, the tool shows a polar-condition note.

Sunrise and sunset times by location

English sunrise and sunset SERPs expect a location-first tool: choose a city or coordinates, select a date, and see local sun times with daylight and twilight context.

cos h_{0} = \frac{sin a - sin φ sin δ}{cos φ cos δ}

h0 is the sunrise or sunset hour angle, a is the solar altitude threshold, phi is latitude and delta is solar declination.

What affects the result

Latitude, longitude, date and time zone determine the displayed local times.
Civil, nautical and astronomical twilight use different solar-altitude thresholds.
High-latitude locations can have midnight sun or polar night on some dates.
The result is a calculator estimate and may differ from official almanacs by small amounts.
