Annotation:

The calculated time for sunrise, sunset, moonrise, is accurate to + - 1 minute. The actual times depend on unpredictable atmospheric conditions that affect the amount of refraction at the horizon. Local topography (e.g., mountains on the horizon) and the height of the observer can affect the times of rise or set even more.

The times of dawn and dusk relate to the beginning of the so-called "nautical twilight" (ie when the sun is 12 degrees below the horizon). All calculations are for sea level.

Calculation of sunset and sunrise times for cities apart of the list of predefined cities are dependent on the exact latitude and longitude coordinates and the time zone you entered.
