Dawn and dusk are not instant. Today in Rio Grande do Sul, civil twilight begins 24 minutes before sunrise, so it is already light enough to walk outdoors at 05:37, and it fades about 24 minutes after sunset. At this latitude the Sun sinks at a shallower angle, so twilight lasts longer than in the tropics. Photographers often plan around the hour after sunrise and the hour before sunset, when the light is warm and soft, and drivers, cyclists and runners can use these times to know when to switch on lights.

Where these times come from
All times are calculated astronomically for Porto Alegre (30.03° S, 51.22° W) and shown in the local time zone (America/Sao_Paulo, UTC-3). Sunrise and sunset refer to the moment the upper edge of the Sun touches the horizon, already counting atmospheric refraction. They refer to the state capital; elsewhere in Rio Grande do Sul the times differ. Each degree of longitude to the east or west moves solar time by about 4 minutes, so inland towns can see the Sun rise noticeably earlier or later than the capital, and a place at a different latitude has a slightly different day length. Values are accurate to within about a minute.
