Sunrise and Sunset Calculator by Coordinates — Times from Latitude & Longitude

Have coordinates but no city name? This calculator works from pure numbers. Enter a latitude and longitude — from a GPS unit, a pin dropped in a maps app, a trailhead listing or a photo’s location data — and get today’s sunrise and sunset times for that exact spot on Earth. It is the version built for photographers chasing first light, hikers timing a descent, campers planning around dark, and drone pilots who fly inside daylight hours.

How to use the sunrise and sunset calculator by coordinates

Find the latitude and longitude of your spot — the next section shows four easy ways.
Type the latitude into the first box. Places south of the equator take a minus sign.
Type the longitude into the second box. Places west of Greenwich (the Americas) take a minus sign.
Click “Calculate Sunrise & Sunset”.
Read today’s sunrise and sunset times for those exact coordinates.

How to get the coordinates of any place

Coordinates look technical, but you are never more than a few taps from them:

A pin in a maps app. Open Google Maps or Apple Maps, press and hold on the spot until a pin drops. The coordinates appear with the pin’s details — copy both numbers exactly as shown.
A photo you already took. Most phones store GPS data in every picture. Open the photo, tap Details or Info, and you will see where it was taken — perfect for returning to a viewpoint you found by luck.
A GPS unit or sports watch. Handheld GPS devices and hiking watches show your current latitude and longitude on their position screen, live, even with no phone signal.
A trail or campsite listing. Trail guides, park websites and campsite listings often print trailhead coordinates so drivers can navigate to the start. Paste them in here before you set off.

One rule covers the signs: north and east are positive, south and west are negative. If your sunset comes out looking like a sunrise, a missing minus sign is almost always the reason.

Golden hour and blue hour: why these two times run a photographer’s day

Sunrise and sunset are not just the edges of the day — they anchor the two windows photographers plan whole trips around. Golden hour is roughly the first hour after sunrise and the last hour before sunset, when the sun sits low and the light turns warm and soft. Blue hour is the short stretch of deep blue twilight just before sunrise and just after sunset, made for city lights, harbours and quiet landscapes.

So the two numbers this calculator gives you are a complete plan: arrive in the dark for blue hour, shoot golden hour as the sun clears the horizon, and know exactly when the light is gone. The same pair of times serves everyone else outdoors. Hikers use sunset to set a turnaround time and be off the ridge before dark. Campers pitch the tent and cook before the light fails. Drone pilots use sunrise and sunset to stay inside the daylight hours their local rules allow.

Searching by city name instead?

If you have a place name rather than numbers, use our sister tool: Sunrise and Sunset Times by city — type any town or city, pick a date, and get sunrise, sunset, solar noon and day length in that place’s own local time. Bookmark this page instead when your location arrives as coordinates: a dropped pin, a GPS reading or a trailhead.

Sunrise and sunset by coordinates – frequently asked questions

How do I find the latitude and longitude of a place?

Open Google Maps or Apple Maps, press and hold on the exact spot until a pin drops, and read the two numbers shown for that pin. You can also open a photo taken there and check its details — most phones save GPS coordinates with every picture — or read the position screen of a GPS unit or sports watch.

What numbers do I enter for places south of the equator or in the Americas?

Use a minus sign. Latitudes south of the equator are negative and longitudes west of Greenwich — the Americas, for example — are negative too. New York is latitude 40.7128, longitude -74.0060. Sydney is latitude -33.8688, longitude 151.2093. Latitude runs from -90 to 90 and longitude from -180 to 180.

Which day does the calculator work out?

Always today. The calculator combines the coordinates you enter with today’s date, so bookmark the page and re-run it on the morning of your shoot, hike or flight to get that day’s times.

How accurate are the times?

The calculator uses the standard sunrise equation (the official 90.833° zenith), so for most places the result lands within a few minutes of the official time — plenty for planning a shoot or a walk. Times are shown in your own device’s time zone, and mountains, deep valleys and places very far north or south can shift the real, visible sunrise and sunset, so treat close calls with care.
