How to use the sunrise & sunset by location
Solar times for a specific location
Sunrise and sunset can differ substantially within one country, so this tool uses geographic coordinates rather than a country alone. The place search supplies latitude, longitude and the associated IANA time zone for the selected result.
The solar events are then calculated locally using PHP’s astronomical sun-position function. Output uses the location time zone and therefore applies the correct daylight-saving or standard time for that date.
What sunrise and sunset represent
The times represent standardized geometric sunrise and sunset. Mountains, buildings, observer elevation and atmospheric conditions can make the Sun visibly appear later or disappear earlier. Weather does not change the astronomical instant but can prevent observation.
Day length is the interval between sunrise and sunset. At high latitudes the Sun may not set or rise on certain dates. Those polar-day and polar-night conditions are reported without inventing a clock time.
Suitable uses and accuracy limits
Solar times support photography, outdoor activities, travel, gardening and daylight planning. Nautical navigation, aviation and safety-critical operations require specialized official or professional sources.
Use a specific place name with country or postal code. When several places share a name, the first result is used and its country, coordinates and zone are shown. Refine the query if those details do not match the intended location.
