What Time Is Twilight Today?
Today's twilight windows for your location are shown above with a live countdown to the next one. Twilight comes twice a day — before sunrise and after sunset — and the indigo bands at both ends of the animated sun path show exactly where they fall today.
The Three Types of Twilight
Twilight is graded by how far the sun sits below the horizon:
- Civil twilight (0° to −6°) — what this page tracks. Bright enough to walk, read, and work outdoors; streetlights come on as it ends. Also the legal definition of "daylight" in many traffic and aviation rules.
- Nautical twilight (−6° to −12°) — dark on the ground, but the sea horizon is still visible, which once let sailors take star sights with a sextant.
- Astronomical twilight (−12° to −18°) — looks like night to most people, but the sky still glows faintly for telescopes. Past −18° is true astronomical night.
White Nights and Polar Twilight
At latitudes above about 60°, midsummer twilight never finishes: the sun dips below the horizon but never reaches 18° (or even 6°) below before rising again — the "white nights" of St Petersburg, Helsinki, and Anchorage. The opposite happens in polar winter, when the sun never rises and twilight is all the daylight there is.
FAQ
What time does twilight end tonight?
Evening civil twilight ends when the sun drops 6° below the horizon — tonight's exact time is in the cards above, with a live countdown.
Is twilight the same as dusk and dawn?
Morning twilight is the period whose end is sunrise — commonly called dawn. Evening twilight follows sunset and ends at dusk. Same windows, different names for the period versus its boundary.
How is twilight calculated?
