Frequently Asked Questions

What is the difference between sunrise and civil dawn?

Sunrise is the moment the upper edge of the Sun appears above the horizon. Civil dawn (civil twilight) begins when the Sun is 6° below the horizon — it's bright enough for most outdoor activities without artificial light, but the Sun hasn't risen yet. Civil dawn typically occurs about 20–30 minutes before sunrise.

What are the three types of twilight?

Civil twilight occurs when the Sun is 0°–6° below the horizon — enough light for most activities. Nautical twilight is when the Sun is 6°–12° below the horizon, dim enough that the horizon is barely visible at sea. Astronomical twilight is when the Sun is 12°–18° below the horizon, after which the sky is fully dark for stargazing.

How do I find my latitude and longitude?

You can find your coordinates by searching your city name in Google Maps and right-clicking on your location, which displays latitude and longitude. Alternatively, search 'my coordinates' in your browser, or use GPS on your phone. Latitude ranges from -90° (South Pole) to +90° (North Pole); longitude from -180° (West) to +180° (East).

How do I determine my UTC offset?

Your UTC offset is the number of hours your local time zone is ahead of or behind Coordinated Universal Time (UTC). For example, US Eastern Standard Time is UTC-5, Pacific Standard Time is UTC-8, and India Standard Time is UTC+5.5. During daylight saving time, add 1 hour to your standard offset.

What is solar noon?

Solar noon is the moment when the Sun reaches its highest point in the sky for the day — directly due south in the Northern Hemisphere and due north in the Southern Hemisphere. It is not necessarily 12:00 PM clock time; it depends on your longitude within your time zone and the equation of time.

Why does day length change throughout the year?

Day length changes because Earth is tilted on its axis at about 23.5°. As Earth orbits the Sun, different hemispheres receive more or less direct sunlight. Days are longest around the summer solstice (around June 21 in the Northern Hemisphere) and shortest around the winter solstice (around December 21). At the equinoxes (March and September), day and night are approximately equal everywhere.

Does sunrise and sunset time depend only on latitude, or also on longitude?

Both matter. Latitude determines how long the day is and how high the Sun gets. Longitude determines the precise clock time of sunrise and sunset relative to your time zone — locations further east within the same time zone see the Sun rise earlier by the clock. Both coordinates together give accurate local sunrise and sunset times.

What happens at extreme latitudes near the poles?

Near the poles, the Sun can remain above the horizon for 24 hours during summer (midnight sun) or below the horizon for 24 hours during winter (polar night). The calculator handles these cases by reporting 'Sun does not rise' or 'Sun does not set' for days when the Sun stays fully above or below the horizon.
