What time does the sun rise in Boston?
Today sunrise in Boston, United States is at 06:21, and daylight lasts 10 hours and 12 minutes until sunset at 16:33. The day actually begins earlier: civil twilight starts at 05:52, when the sky brightens while the sun is still below the horizon. Solar noon, when the sun is at its highest, falls at 11:27. 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.

Civil twilight reaches 6 degrees: in Boston it ends at 17:02 today, the hour when you can no longer read outdoors without artificial light. Nautical twilight extends to 12 degrees, today until 17:36: while it lasts, the sea horizon stays visible and sextant navigation works. Astronomical twilight ends at 18 degrees, today at 18:09: from then the sky is fully dark and even faint stars appear. In the morning the sequence runs in reverse, starting at 04:46.
