Sunrise and Sunset Times for Any Location

Calculator Use

Find sunrise and sunset times for any location on planet Earth. Enter latitude and longitude and select the time zone for your location.

This sunrise sunset calculator finds the time of day for sunrise, sunset, dawn and dusk given latitude, longitude and UTC offset.

You can also find solar noon or dawn/dusk twilight in terms of civil, nautical or astronomical twilight. Learn more about the different types of twilight below.

How to Enter Latitude and Longitude

Enter degrees and minutes as whole numbers, or degrees and minutes as a decimal number. If you enter degrees as a decimal number you should leave the minutes field blank.

If your location is west of the Prime Meridian you should enter a negative longitude. If your location is south of the equator you should enter a negative latitude.

Examples of Lat Long Coordinates

Using the geographical coordinates for Portland, Oregon in the US, enter them into the Sunrise Sunset Calculator like this:

Find Coordinates for any Geographical Location

Use Google Maps to find your location, for example, Portland, Oregon.

Right click a specific point on the Google map and you will see the latitude and longitude coordinates displayed, for example 45.51421, -122.68462.
This stands for latitude 45.51421 (north of the equator) and longitude -122.68462. The negative longitude means the location is west of the Prime Meridian which is at 0° longitude.

For Portland, OR be sure to set the time offset to UTC -08:00 when in Pacific Standard Time PST. If you're in a location that is in daylight savings time be sure to add an hour to the offset. So in Pacific Daylight Time PDT, Portland's UTC offset will be one hour ahead at UTC -07:00.

Astronomy Definitions for Sunrise Sunset Times

Sunrise

Sunrise is defined as the moment in the morning when the upper edge of the sun is in line with the horizon at zero degrees (0°).

Sunset

Sunset is defined as the moment in the evening when the upper edge of the sun is in line with the horizon at 0°.

The Three Types of Twilight

Twilight is the time when the sky is somewhat light but the sun is not above the horizon. You can see twilight in the morning at dawn, and in the evening at dusk. There are three types of twilight: civil, nautical, and astronomical.

Civil Twilight, Dawn and Dusk

Twilight occurs twice a day, once at dawn and once at dusk. Civil twilight is defined as the moment when the center of the sun is 6° below the horizon, up until sunrise. This is what people generally mean when they say "dawn" or "dusk".

Dawn

The moment in the morning when the center of the sun is at a depression angle of six degrees 6° below the horizon. Morning civil twilight occurs from civil dawn until sunrise.

Dusk

The moment in the evening when the center of the sun is at a depression angle of six degrees 6° below the horizon. Evening civil twilight occurs from the point of sunset through civil dusk.

Nautical Twilight, Dawn and Dusk

Nautical twilight occurs when the center of the sun is 12° below the horizon.

Nautical Dawn

Nautical dawn is defined as the moment in the morning when the center of the sun is at a depression angle of twelve degrees 12° below the horizon. Nautical twilight occurs from nautical dawn until the point of civil dawn.

Nautical Dusk

Nautical dusk is defined as the moment in the evening when the center of the sun is at a depression angle of twelve degrees 12° below the horizon. Nautical twilight occurs from the point of civil dusk until nautical dusk.

Astronomical Twilight, Dawn and Dusk

Astronomical twilight occurs when the center of the sun is 18° below the horizon.

Astronomical Dawn

Astronomical dawn is defined as the moment in the morning when the center of the sun is at a depression angle of eighteen degrees 18° below the horizon. Astronomical twilight occurs from astronomical dawn until the point of nautical dawn.

Astronomical Dusk

Astronomical dusk is defined as the moment in the evening when the center of the sun is at a depression angle of eighteen degrees 18° below the horizon. Astronomical twilight occurs from the point of nautical dusk until astronomical dusk.

Solar Noon or Transit

Solar noon is defined as peak of the sun's transit, which is the moment when the sun is halfway between sunrise and sunset. Solar noon is not necessarily the same as noon time of the day.
