Sunrise Sunset Calculator
Get sunrise, sunset, solar noon, day length, all three twilights and golden-hour windows for any place on Earth and any date — shown in the location's local time.
Twilight
| Civil | 06:38 → 18:47 | Bright enough to read outside |
| Nautical | 06:06 → 19:19 | Horizon visible at sea |
| Astronomical | 05:34 → 19:50 | Sky fully dark for astronomy |
Golden hour
Formula: NOAA solar algorithm with the standard 90.833° zenith for sunrise/sunset (accounts for refraction and the Sun's apparent radius). Near the poles some events do not occur — shown as — during polar day/night.
How to use this tool
Search a city or type latitude/longitude directly.
Pick a date (defaults to today).
Read sunrise, sunset, twilight and golden-hour times in local time.

How it's calculated
Computed with the NOAA solar algorithm: solar declination and the equation of time from the Julian date, then hour angles for the standard 90.833° sunrise/sunset zenith (accounting for refraction and the Sun's apparent radius), 96°/102°/108° for civil/nautical/astronomical twilight, and 84° for the 6° golden-hour edge. Near the poles some events do not occur and are shown as unavailable during polar day or night.

Frequently asked questions
How accurate are the times?
Within about a minute for most locations — the NOAA algorithm is the standard reference used by almanacs.
What is the difference between the three twilights?
Civil (sun 0–6° down): bright enough to read outside. Nautical (6–12°): the horizon is still visible at sea. Astronomical (12–18°): the sky is fully dark.
What is golden hour?
The period when the sun sits 0–6° above the horizon, giving warm directional light — shown as morning and evening windows.
Why are some values missing?
Inside the polar circles the sun may not rise or set for days at a time; those events are then genuinely undefined.
Are times shown in my time zone or the place's?
The place's local time, resolved from its coordinates — so you can plan for a trip abroad.
Does it account for mountains or buildings?
No — times assume an ideal flat horizon. Terrain can shift visible sunrise/sunset by minutes.
What is solar noon?
The moment the sun crosses the local meridian at its highest elevation — not always 12:00 on the clock.
Why does day length change through the year?
Earth's 23.4° axial tilt makes the sun's path longer and higher in summer, shorter and lower in winter.
