The three twilights are just how far the sun is below the horizon: civil to −6° (bright enough to read outside), nautical to −12° (the horizon is still visible at sea), astronomical to −18° (true darkness for stargazing). Golden hour is the warm, low-angle light photographers love, when the sun sits between −4° and +6°; blue hour is the deep-blue band just beyond it, from −6° to −4°. A dash means the sun never gets that low here on this date.

What time is sunrise in Buenos Aires today?

The card above computes it live in your browser for today's date, using Buenos Aires's coordinates — along with sunset, solar noon, first light and last light, all in Buenos Aires's own time zone.

What are first light and last light?

Civil twilight — when the sun is less than 6° below the horizon. It's bright enough for most outdoor activities before sunrise and after sunset.

Why do the times change every day?

Earth's tilted axis means the sun's path moves through the seasons — days lengthen toward the summer solstice and shorten toward the winter solstice, so sunrise and sunset shift a little every day.
