Asunción, Asuncion · 15 July 2026
Precise astronomical times. Sunrise, sunset and twilights are computed from the town’s coordinates (NOAA algorithm), with daylight saving included. Everything runs in your browser, no account, no data sent.

Due east and west only around the equinoxes. On the longest day it rises in the south-east (azimuth ~117°) and climbs to about 88° above the horizon at noon; on the shortest day it rises in the north-east (~64°) and peaks at just ~41°.
Because of longitude and latitude: more easterly towns see sunrise earlier, and latitude sets how much day length swings with the seasons. Times are computed from Asunción's exact coordinates.
Times use the America/Asuncion time zone (UTC-3 all year). The zone does not observe daylight saving time, so no clock changes apply.
They are how far the sun is below the horizon: civil (to −6°, still light enough to read), nautical (−6° to −12°) and astronomical (−12° to −18°, fully dark). All three are shown for Asunción.
