Times are calculated, not measured, and are typically accurate to within about a minute. Actual sunrise/sunset can shift slightly with elevation and local horizon obstructions.
What time is dawn?
What time is dawn? Dawn happens in three stages before sunrise: astronomical dawn (sky first begins to lighten, sun 18° below the horizon), nautical dawn (12° below), and civil dawn (6° below, when there is enough light for most outdoor activity). Choose a location and date above to see all three.
