Sunrise and sunset in Dallas

Today the sun sets at 19:42 in Dallas, United States, after 12 hours and 36 minutes of daylight that began with sunrise at 07:06. Darkness does not fall at once: civil twilight lasts until 20:07, and until then you can still read outdoors without artificial light. Sunset shifts by a minute or two each day because of the tilt of the Earth's axis: this page has the calendar for the whole year, with sunrise and sunset on the 1st and 15th of each month. Times are computed with the NOAA solar algorithm from the city coordinates and shown in its local time zone.

Today sunrise in Dallas, United States is at 07:06, and daylight lasts 12 hours and 36 minutes until sunset at 19:42. The day actually begins earlier: civil twilight starts at 06:41, when the sky brightens while the sun is still below the horizon. Solar noon, when the sun is at its highest, falls at 13:24. Sunrise is the moment the upper edge of the sun appears on the horizon, accounting for atmospheric refraction: the same definition used by astronomical observatories.

The three twilights differ by how far the sun has dropped below the horizon.
