when does the sun set

The time of sunset varies depending on the location and the date. Sunset generally occurs once every 24 hours, except near the poles where phenomena like polar day or night can occur. The exact time of sunset depends on the viewer's position on Earth (latitude and longitude), altitude, and time zone. Throughout the year, sunset times shift due to the Earth's axial tilt, rotation, and orbit around the Sun. For example, on September 27, 2025, in Berlin, Germany, the sun set at approximately 6:55 PM local time. To find the precise sunset time for a specific place and date, it is best to consult a local astronomical calendar or a dedicated sun position calculator.
